Best road tyres

March 26, 2022April 25, 2014 by tejvan

Now the winter is officially and very firmly behind us (cue return of rain, sleet and snow) it’s time to take off the winter road tyres and choose the best summer road tyres for all the upcoming halcyon days of riding on dry smooth tarmac in temperatures approaching the mid 30s.

Depending on the tyre you choose, there can be a big difference in terms of rolling resistance – up to 30 watts worth between best and worse performing. Also, The faster you go, the more you will notice the difference.

Over the years I’ve tested quite a few different road tyres. To some extent it becomes hard to choose between different models. But, the good news is that I feel the technology of tyres has improved in recent years, giving cyclists a really good choice of tyres. Because I have so many sets of wheels, I’m often riding several different types of tyres / tubulars at the same time, which gives an idea of how different tyres compare.

I would say the golden rule of buying tyres is don’t penny pinch. It is invariably worth getting a relatively expensive tyre. The cheapest models of tyres tend to be poor value.

When choosing tyres, it is always a trade off between different factors

Low rolling resistance
Low weight
Puncture resistance
Aerodynamics
Grip on the road
Ease of maintenance – changing in case of puncture e.t.

Generally racing tyres will be light, low rolling resistance, but you sacrifice some puncture resistance. I’m often torn between using the lightest tyres and risk having to walk along a dual carriage way because of puncturing. It is only on hill climbs that I really throw caution to the wind and ride track tubulars which are ridiculously light. For my general road bike, I tend to go for a good all-rounder, like Continental Gatorskin / 4 season. For racing, I use tubulars – either Continental Competition (Good puncture protection, but definitely not best rolling resistance) or Corsa Crono Evo)

Fastest tyres

When buying tyres, it is hard to know the rolling resistance that the tyres offer. From trial and error and testing, you can notice a difference between different tyres – especially when doing time trials, but it is always tricky to measure exactly. The graph below shows the power required for different tyres, which were tested at Continental in Germany Link. If it was tested at Continental, it’s interesting that Continental tyres don’t come out so well on the rolling resistance.

The test shows the rolling performance at 7 bar (101psi) and the power needed to overcome rolling resistance of the tyre. This shows, there is over 20 watts difference between the worst performing tyre (Hutchinson Top Speed) and the best performing tyre. With a threshold power of 300 watts, 20 watts is a lot to give away to a slow tyre.

Vittoria Open Corsa Evo CX

I have used the Vittoria Open Corsa Evo, but I was probably put off re-buying by the relatively poor puncture protection. However, looking at the rolling resistance, it is a tyre which is really focused on performance, with very low rolling resistance. If you want one of the fastest tyres, this is a very good choice. The weight is just 210 grams for the 23″ option.

Energy bars for cycling

January 7, 2017April 4, 2014 by tejvan

Over the years, I’ve taken a huge variety of energy bars and food on rides. These are a quick review some of the bars I buy most often.

What to look for in an energy bar?

High level of carbohydrate / low fat.
Mostly complex carbohydrate, with some carbohydrate which sugars. Medium GI index.
High concentration of energy for size.
I tend to take a variety of energy bars. I’m not particularly fussy which brand. But, a bit of variety helps in various aspects – even if just making eating of the bike more palatable.

Specific Cycling energy bars vs non-Specific energy bars

For a specific energy bars developed for the cycling market, you will pay around £1 – £1.50. You can get a similar level of carbohydrate through much cheaper non-specific energy bars. For example Kellogg’s Nurti Grain contains around 35g of Carb, but only costs 40p. If you don’t want to pay £1.20 for 30 grams of carbohydrate, you don’t have to.

However, I still like to pay ‘through the nose’ for branded energy bars because:

Psychological habit. You just assume if it’s more expensive, it must be better. ( a common attribute of cycling shoppers)
The energy bars tend to be more concentrated, and relatively lower fat.
I would get bored of eating Kellogg’s Nutri Grain and the like all the time.
I always like to believe manufacturer’s claims that eating their energy products will make me go ‘15% faster’ – even if it is rather a dubious claim!
Proprietary energy bars often contain trace elements and electrolytes which may help in different aspects of nutrition and energy consumption. (even if I’m not entirely sure how)
It’s handy to buy a big box of 24 energy bars. You always have something in stock to take on long rides.

Some of the best Energy bars I buy

Powerbar 55 gram- Energize

Contains slow release carbs, = brown rice, oats and maltodextrin for slow release energy.
Contains 2:1 Glucose / Fructose, which is claimed can increase total energy uptake
Some electrolyte (sodium) + vits and minerals, such as magnesium.
1.9g fat per bar
38 gram of carbohydrate (sugars 23g) , per 55 gram bar. Quite a high % of carbs which is sugar (from fructose)
Review: Quite concentrated energy source. Needs a bit of chewing and you need to take some water with it. I do like the taste of the chocolate variety. Not too sweat. Good for long rides, and very thin for slipping in back pocket. One of most expensive though. I wouldn’t use in a race, because it does slow you down a little chewing through the bar.
25 *55g Powerbar at Wiggle £29.99

Torq 45g Energy bar

Mixture of GI foods. usual maltodextrin, oats, plus fructose based energy
30 gram of carbohydrate per 45 gram bar 22g sugars)
Review: These are pretty enjoyable to eat. They are moist and tasty. This is important for long rides, where you often need something attractive to get you to eat. 30 gram of carb makes it easy to calculate – 2-3 an hour. I wouldn’t just rely on eating these on a very long ride, it becomes a bit too much fruit.

Faster by Michael Hutchinson Review

April 5, 2014March 28, 2014 by tejvan

‘Faster: The Obsession, Science and Luck behind the World’s fastest cyclists‘ by Michael Hutchinson is a look at what makes the world’s elite cyclists go faster. Is speed due to natural talent, genetics, training, diet, cutting edge technical equipment or a combination of all of these? During his investigation, Hutchinson reveals a lot about his own personal journey / obsession with going faster, which is both revealing and humorous. He also gets to interview some of the leading figures within the successful British Cycling / Team Sky set up.

I read it pretty fast, and enjoyed it because:

I share a similar obsession with trying to go faster on the bike (though realising I haven’t spent the past 10 years sleeping in an altitude tent does make me feel a bit like an amateur)
It is written well, with a good sense of humour. This is a big plus for another cycling book. Somehow Hutchinson can even make the law of turbulence seem entertaining (not that I really understood what he was saying about turbulence) If there is one criticism of his writing style, there is often one too many sub-clauses; the end of the sentence is quite divergent from the start – but since I’m quite prone to liberally adding sub-clauses myself – it’s a fault I’m happy to forgive.
Within the several chapters, there are a few nuggets of wisdom which actually might help me go faster (or at least save me thousands of pounds in spending money on things which aren’t worth the outlay.)
It’s a bit of a coup to get so many interviews with the hierarchy of Team Sky and British Cycling. There is often good advice from the Team Sky / British Cycling coaches. I like the fact pro-cyclists say they don’t mind sharing interval sessions. As they say it’s one thing to know what to do, it’s another thing to actually do it.

Personal journey

I never relate so well to general cycling ‘text’ books on how to go faster. But, I do enjoy reading the personal experiences of cyclists who have been there and done it, especially if they do similar races to myself. It is interesting to read the highs and lows of Hutchinson’s career from going too hard at the 2002 Manchester Commonwealth Games (finishing in 15th place – though Hutchinson says he could never bear to look where he finished) to a creditable 4th place in 2006 and 2010. Overall, you get the impression of someone enjoying the process of trying to go faster, even if it involves some crazy decisions. But, this ongoing effort seems to mean as much as the 50 domestic national titles. Important for those who don’t have 50 national titles.

Power figures and different types of riders

These days, there is always an interest in power figures (especially when you’ve just bought one and think it might be broken because the power output is much less than you would like to say). If I remember correctly, Hutchinson says he peaked at 470 watts for a 10 mile TT. His recovery rides are at an average power that I might struggle to do if I went all out in a 10 mile TT. Power figures are not dropped in just to boast about, there is usually a point, often self-deprecating as to why very big VO2 max and high power figures are not necessarily enough.

Just to prove the point, I can claim to be one of the very few people to beat Hutchinson in a time trial, when I wasn’t even riding a TT bike, but a humble road bike. (2012 National hill climb on Long Hill). That’s the beauty of cycling, Hutchinson can catch me for 16 minutes in the National 100 mile TT, but when the road goes uphill, it can favour a completely different kind of rider. From the likes of track sprinters like Chris Hoy to mountain goats like me, there is a huge range of disciplines which suit different riders. This is something the book explains quite well Hutchinson was built for endurance time trials. A near perfect physiology, but a cautionary reminder, even with 50 national titles, there is always someone more talented, more lucky in the genetic lottery, or better at training and all the rest.

I read the book in two days, but, I’m already struggling to remember what I’ve read. It is definitely the kind of book which benefits from careful reading, and also reading a second time. There are some concepts which are more complicated than just ‘pedalare’ The irony of reading the book, is that I approached it very much with the same motivation as Hutchinson approaches cycling – what can I take out of this book which makes me go faster on the bike? I’m sure many cyclists will relate to that constant questioning of life decisions

– but, what will make me go faster?

It’s the question always at the back of your mind. The book helps to clarify how as athletes we carry this motive around with us. It’s not quite that we need to set up Aerodynamics and Speed Freaks Anonymous, but it is a humorously cautionary tale on the fine line between dedication and obsession.

Nuggets of Wisdom

After reading the book, some nuggets of wisdom which I remember:

The best skinsuit may make substantially more improvements in aerodynamics than upgrading your bike. Why spend £7,000 on a new time trial bike, when you can spend £1,000 on a cutting edge skin suit? (because the bike looks better?) If you really want to go faster for free, forget breaking into a bank to find £7,000 for a new bike. Try breaking into British Cycling headquarters and find those skinsuits put in a cardboard box after the UCI decided they were too fast. Somewhere in a Manchester cupboard is aerodynamic gold.

Quarq power meters review

March 27, 2014March 27, 2014 by tejvan

This is a review of Quarq power meters which I’ve been using for the past six months.

I bought the model Quarq Elsa. It weighs 735g. It was 85 grams lighter than the cheaper Riken model. The Riken has non hollow crank arms and a heavier spider. The Quarq Elsa cost me around £1,500 from local bike shop.

quark-elsa

How the Quarq works

The Quarq power meters work by measuring the torque (pressure) applied to the chainset and crank * cadence. Torque is measured by tiny strain gauges, which measure how much pressure is applied. The power readings are relayed by ANT to a suitable power device.

Much of the cost of the Quarq is the cranks themselves. If you already have a good crank, you are buying a surplus crank arm. It does make it quite an expensive power meter, especially with cheaper models coming on the market.

To swap between bikes, you need to remove the crank arm and fit to the bottom bracket. This job is OK, if you have the right tools. In theory, I should be swapping the Quarq power meter between my road bike and TT bike quite frequently. But, in practise, I don’t want even that 10-15 minute job. So I just end up leaving it on one time trial bike. I like riding with a power meter, but not enough to religiously change it every time I swap bikes.

Features of the Quarq Elsa

Power Balance. The Else features independent left-right leg power measurement. Quarq say that it measures total torque on left / right leg. It doesn’t just include the down-force, but also measures power from pulling up on the pedal. It displays the power balance as the % of work done with left / right, e.g. 45% / 55%. I haven’t yet used this feature, because left/right is not supported by a Garmin 500. However, it is a good feature to have given my past left-right leg imbalances. I would like to upgrade my Garmin, when it seems like there is money to justify thr expense.

Adamo saddle review

November 1, 2016February 21, 2014 by tejvan

Adamo saddles are a unique design of saddles by the company ISM. The basic principle is to cut out the ‘dead’ area on a saddle. Focus saddle and padding on your ‘sit’ bones which is the most important thing and avoid the ‘numbness’ associated with sitting on a conventional saddle.

adamo-ISM-break

It certainly looks distinctive. This is the ISM, Adamo ‘Breakaway’

Motivations for buying an Adamo

In early Feb, I was doing a 90 minute effort on the rollers on my time trial bike. After an hour, the pain and discomfort in crotch area was really bad. By the end of the session, I just couldn’t bear to be in the time trial position. It felt like everything was getting squashed and numb. I wanted to finish the 90 minutes on rollers, but I could only do it by getting out of the saddle (which on the rollers is tricky)

Also, in last years National 100 (5th in a time of 3.46) the last 10 miles were ruined by great pain in shoulders and groin. I was squirming all over the bike because of the numbness and lost substantial time.

Since, I want to do a 12 hour time trial on the TT bike, I knew something had to change. Adamo saddles have been recommended to me by quite a few time triallists. Not everyone is convinced, but some people seem quite passionate – and it is rare for people to get passionate about a saddle (apart from maybe Brooks). Just looking at the Adamo Saddle made me think it was more comfortable. Like all great inventions and designs, once done, it seems so intuitive to put the padding where you need it and cut away where you just get numbness.

Adamo Time trial version

Adamo produce an almost bewildering array of variations on their original saddle. It would be hard to test them all. But, since I was buying for time trials, the obvious option was to buy the time trial saddle.

adamo-scale

Adamo TT weight 274 grams – lighter than most other versions.

Adamo also claim that for the time trial saddle:

‘The design allows for increased hip rotation, thus decreasing a rider’s aerodynamic drag and opens the diaphragm for easier breathing. Riders report an increase in wattage due to the more aggressive positioning. Sloped front arms provide extra relief to the superficial perineal space.”

This wasn’t my motivation for buying, but increased wattage seems a good thing.

Review of riding experience

The first ride was two hours on the rollers on the time trial bike. That’s quite an aggressive position and involved not stopping or getting out of the saddle.

It was a revelation. The improvement in comfort was very marked. I would say at the end of 90 minutes, there was 60% less pain, and after two hours I could still have kept going. That awful feeling of numbness just wasn’t there. This is the most important feature of the saddle, it really does work and makes long distance time trialling less painful.

Since that first roller session, I’ve done two four hour rides on the time trial bike. Again, it is remarkably comfortable for four hours in a race position. I will review after doing a 100 mile race and 12 hours. But, I’m confident that the saddle will make a significant difference and justify its price tag.

It is not to say it is a panacea. After two hours on the rollers, my seat bones (the bones which make most contact with saddle) were a little sore. You could tell they had absorbed a lot of weight. But, it is a very manageable ache, and more noticeable when you get off the bike. To be honest, if I was racing on an open road, I would have moved around more and given my backside more breathing space than two hours on the rollers.

Is there increased hip rotation? ISM claim increased hip rotation, and I when I spoke to Matt Bottril last year at the BDCA 50, he was saying he found the Adamo saddle helped his power.

But, to be honest, I was so absorbed in noticing the improved comfort, that I didn’t really notice much difference in actual power I was putting out. Maybe there is an advantage, I would have to retest.

Update after nine months use – One downside of Adamo is that I have had chaffing on the outside of the saddle – on the inmost thighs. You don’t notice whilst cycling, but after it has been raw and I’ve been putting on Sudocrem – it’s not a show stopper, just a bit irritating.

Custom cycle clothing alterations (cheap)

February 5, 2014 by tejvan

Recently, I sent a packet of cycle clothing to be altered by Alex Laycock. I had

baggy-arms

3 Impsport skinsuits (with baggy arms)- You spend £180 on an Impsport custom body suit and it comes back with baggy arms like this.
1 winter jacket (missing zip) back pockets getting worn
1 pair of shorts (expensive Assos variety, ripped in Portugal)

The repairs and alternations were done for £40, plus £11 postage. I think that includes the cost of a new zip which was £10.

Alex has done quite a few time trials herself, and is used to mending lycra. Alex Laycock at Yell.com

Make do and mend

A comment by a reader, reminded me to post about this:

I had this problem with my Night Vision jacket and I wrote to Altura – not to complain (as the jacket was just over 12 months old) but to ask if they could repair it or recommend someone who could. Their reply was unhelpful,to say the least, effectively , “well, you need to buy another as we don’t repair them and we don’t know anyone who can”. Great jacket – rubbish after sales service. Can’t recommend them!

I don’t know if waterproof jackets can be mended, but it’s worth finding out. I might even get a new zip for my Altura jacket.

There’s a lot to be said for make do and mend. Especially when tights / legwarmers get ripped falling off.

Review of leg warmers

February 4, 2014 by tejvan

I’ve accumulated quite a few leg warmers over the past 10 years. This is a review of the different models I’ve been using.

From left to right

Specialized
Altura ergofit
DHB Vaeon Roubaix
Castelli nanoflex
Blue ‘prorace’ – discontinued.

Not featured here, I’ve also tried on some Impsport custom legwarmers.

Features I look for in leg warmers:

Not too tight so when cycling you don’t feel they are restricting your movement.
Stay in position, don’t roll down your leg
Warm. – different degrees of warmth depending on conditions. I like to have a thin pair, and a warmer pair.
Zip is useful for taking off over cycling shoes

To a large degree, some of these features need picking the right size as much as the individual brand.

Specialized

I like the Specialized leg warmer because it has a soft and flexible fabric. When you put it on, it doesn’t appear too tight. They are also quite thin, which makes it good for those times when it’s warming up, but not quite ready for shorts.

I have size L. It is prone to slip down, but if you put it underneath a pair of shorts, then it stays fine. Because it is thin, it dries pretty quick.

I’ve had it for over 5 years and has lasted well. Simple, but effective. They seem to have discontinued this model, which is a shame because it has been a very good product. The new Specialized leg warmer is called the Specialized EZ, I haven’t tried it, and unfortunately, it’s a bit more expensive (up from £32 to £40). Specialized EZ at Evans

Altura Ergofit

This was one of the most expensive leg warmer. The idea is that it comes pre-cut in the shape of a leg. It doesn’t lie flat, but has the bend built into the knee. The idea is that anatomically designed for your leg, it stays in place whilst offering greater freedom of movement.

Initially I ordered a size L, but this proved too big for me. It wouldn’t stay up and was very long. I sent it back and got a size M. This definitely stayed up, but it was a real struggle to get the leg on. The end of the leg warmer is stiff and small, to get it over your foot you have to take off your socks and really give it a good yank. Also, after a few weeks, I developed a hole in the stitching. The leg warmer felt quite tight when riding.

This has been the most disappointing leg warmer, because it isn’t comfortable and is difficult to get on, causing the stitching to come loose. It may just be unlucky with the sizing, but large felt too big, and medium felt too small. It seems a good idea to have an anatomical fit for the shape of the leg, but somehow it didn’t work for me. If you look at other reviews, other people are more positive, so you might have a different experience.

Clip on SKS Mudguards review

November 22, 2015January 27, 2014 by tejvan

For the past four years, I’ve been using different types of SKS mudguards on my winter training bikes. Overall, I’m very pleased with the product. They do the main job of keeping the worst spray off your clothes. They are also quite easy to fit and adjust. They have also proved satisfactorily resilient.

Original SKS race blades.

I bought these original SKS race blades about four or five years ago. I can’t remember how many years, but they are still going strong.

After a few years, I once had a problem with the black supports coming away from the metal mudguard, but a bit of super-glue did the trick and they are still working on this Ribble.

SKS Race blade mudguard

This came out about two years ago. I was sent a free review copy. I was pleased to get a free review copy because I probably would have been willing to buy. They are an improved version of the original race blades. They have better adjust ability and a bit longer protection at the end, with those clip on flaps. They look pretty elegant with a smart carbon finish.

Advantages of SKS race blades

They are quick to fit on. No tools are needed. Just adjust with your hands. If they do rub, it is usually easy to fix by moving the different parts of the adjustable mudguards.
You don’t have to take off brakes to fit.
They are good for road bikes with narrow clearance between wheel and frame/brake
They are light only 250 grams, and are quite unobtrusive on the bike.
They are quiet with no rattle, like I used to get on the old fashioned mudguards.
They are like quick release wheels. It’s less than 30 seconds to take off, and perhaps a minute or two to fit on. Excellent if packing a bike up.
They have proved quite robust.
You can choose the wide road version or narrow road version depending on size of road tyres. The narrow are for 25″ and less.
With a bit of fiddling, they fitted my unusually shaped forks on this Ribble. There is also quite a narrow clearance between wheel and frame on this bike. Though whether they fit all bikes, I’m not sure.

Disadvantages

Unlike traditional mudguards they don’t offer all round wheel protection. You get even more water and mud flying out by the rear brake, so it needs a bit of cleaning.
They are not quite as solid as the more traditional muguards. If you lean your bike against wall with mudguards, they may get put out of shape, requiring adjustment.

Stages power meters

January 16, 2014 by tejvan

Stages power meter promise reliable power meter recording at a relatively cheap price. Whilst many SRMs can go for over £2,000. Stages power meters will be £599 (For Shimano 105) to £799 (Shimano Dura Ace 7900). Not only that but they are lightweight (20grams) and easy to switch between bikes.

This summer I spent quite a bit of time researching power meters and I came to the conclusion, I wanted to get the cheapest one. For me, this was Quark, I ended up spending £1,400 and it was a big hole in the cycling budget.

Quark Elsa

Firstly, the Quark experience has not been so good. A few weeks after buying (and after one race) it broke. We spent ages trying to fix the power meter reading, but the problem was in the crank arm itself so with help of Beeline we sent it back to the distributor. After a delay they sent it back saying it worked. But, it didn’t work, and they hadn’t even put a battery in it. Then we had to send back again. Eventually, four months after it stopped working (Sep 15) I’ve finally got it back in working condition yesterday (Jan 15). It would have been interesting, if not useful being able to use for the hill climb season. It was a lot of toing and froing between the bikeshop. Though in retrospective, I was glad I bought it from Beeline, as they were very helpful in dealing with the Quark distributor.

Whilst the Quark was in the workshop, getting returned , I came to hear about a new power meter called Stages which you just fit to a crank arm. I soon started to regret buying Quark and thought if I’d waited I could have saved £800 and the pain of my Quark not working. Stages seemed to give everything I want from a power meter.

Advantages of Stages

Very light 20 grams! (important for hill climbers)
Easy to put on – Even easier than Quark. Even I a self-confessed non bike mechanic could move Stages around without even having to drive bike to bikeshop (something I dislike having to do)
Much cheaper than other power meters.
You don’t have to worry about changing wheels / changing bikes. As long as you have same crank arm (which I do) it is quite easy to take off and put on another crank arm. This is a big bonus for me, because I have so many different bikes and wheels.
Reviews suggest consistent power meter readings.

Too good to be true?

I’ve already splashed out £1,400 on a Quark, but I plan to leave this on my time trial bike. Once you get used to riding power, you want to see what you do on your other bikes. Even though I only used it for four weeks, I would like to have power meter on road bike to measure hill climb interval efforts. The problem is that I often change from road bike to TT bike almost every day. If I was a pure time triallist one pm may be enough. But, I’m not. Stages seems the obvious choice for a second power meter. Only £700 or £800 so it’s pretty enticing because it doesn’t blow the budget completely.

Altura night vision flite jacket – long term review

January 7, 2017January 9, 2014 by tejvan

I’ve been using this Altura night vision jacket for over a year. I received it last year as a free product for review.

In summary: it is an excellent light weight / breathable jacket, that you can keep in back pocket or saddle bag. Even after consistent rain for an hour, you stay relatively dry and warm, yet you don’t sweat excessively.

The first downside to the jacket, is that in my case the zip didn’t work. I can’t undo it, without a long time of frustrating tugging and pulling. I have to leave zipped up, and just put over my head. On noting this flaw in the product, I mentioned to the Altura rep, who sent the jacket in the first place. He replied by saying, ‘OK, please don’t mention in your review.’ I never heard anything else, like perhaps a replacement jacket. It wasn’t exactly the most amazing piece of marketing strategy and customer care.

In fairness, I think I was unlucky. Looking at other online reviews, I’ve not noticed anyone else complain about a broken zip. Perhaps if you had bought a jacket, you would have got better after sales service. The bizarre thing is I keep thinking the jacket is so good, it’s worth buying one just to get one with a working zip, but in the end it doesn’t seem worth the £70 just for jacket with a working zip so I use this good jacket which needs unorthodox putting on. It means I have to stop to put it on, but to be honest I’m no good at putting on jackets whilst cycling – like the pros anyway.

Sizing

I chose a size L because I’m tall, (6ft 3″) and have long legs. I’m as thin as the proverbial hill climb whippet (36″ chest maybe) so it is inevitably baggy. But, it’s not too bad, I’ve usually got quite a few layers underneath anyway. It does make a difference having a waterproof jacket which goes down just past your wrists. Helps to keep your hands warm. I like it because it seems designed for the racing position. It’s a little on the short side when standing up, but quite good in position.

Waterproofing and breathability

When looking for a waterproof jacket, there seems to be a three way trade off

Price
Waterproofing
Breathability

To score highly on both 2 and 3, you need to pay a lot. At £70, this jacket is quite expensive for a small fold away jacket, but it offers an excellent combination of waterproofing and breathability. This is definitely a proper waterproof jacket (as opposed to ‘water resistant’) I’ve been out in some heavy rain, and feel securely protected from the worst of the weather. But, it’s never too hot, and you can go as hard as you like up hills without becoming excessively sweaty.
