Different attempts to save weight on the hill climb bike – with varying degrees of success and cost.

Originally posted in 2014, updated for 2015 season.

How much difference does weight make?

Firstly, how much difference does reducing weight make? As a rough rule of thumb, for a hill with 100m height gain, losing 1 kg, will save you 2 seconds. Jackson Bridge is 150m height gain over 0.9 miles. If you lost 2 kg, you could save 6 seconds. 6 seconds could be the difference of several places in a National hill climb championship.

Easy marginal gains

• Take off bottle cage / water bottle, bell, saddle pack. (I have done 2 hill climbs with water bottle still on bike)
• Buy lightweight carbon stem / saddle. Often give biggest weight saving for the money.
• Lightweight wheels. Often the easiest way to significantly reduce weight on an ordinary road bike
• Remove garmin.
• Remove any surplus clothes. choose lightweight clothes.
• Make sure your bowels are empty before the race. I find bottle of San Pellegrino mineral water the night before helps to keep you ‘regular’ so to speak.

These are some other ‘marginal gains’ I’ve tried over the years.

1. Cutting off fabric from saddle

This was motivated mainly because my Tune saddle looked a bit frayed. An expensive saddle – but the fabric was coming away. Rather than glue it back down, I thought the excess fabric needed cutting off. The hope was it would look neater and save weight into the bargain.

I was a bit disappointed with the result – Total weight saved – 0 grams. But, psychological advantage – incalculable.

2. Cutting the end off cables

My local bike maintenance shop Reg Taylor are very good, but they aren’t used to catering for the weight weenie hill climbers. The cables always come back with nice long bits of spare cable and neat cable tidies at the end. I kept looking at these for a couple of weeks, but I knew they were doomed – it’s just something asking to be cut. I got great joy getting out the cable cutters and snipping off free weight. Zero cost, no power lost, possibly even a fractional aero gain.

• Weight saving 1 gram – Just 1g down, 5,999 grams to go.  All that metal for a measly 1 gram! It’s harder than you think.

Cutting skinsuit

In 2014 I got a National Champions skinsuit by Impsport. I made the mistake of getting the cheaper version. When I put it on, it was less skinsuit more inflatable parachute. I had it sent to a tailor (Alex Laycock) to make it more suited to a stick thin hill climber, rather than your average cyclist. But, even then the arms were too long and these end cuffs – although they look quite good – stuck out in the wind quite a bit. It didn’t look very aero or very smart. Eventually I got out the scissors and cut these offending bits off – a shame really. The motivation was to make it look better, but as an added bonus the operation saved a whole 11 grams.

The weight of clothes can easily add up. When I rode 2013 national champs, I just wore two pair of thermal socks, (pic) which I later weighed at over 100grams. I think some kind soul took pity and next year sent me a pair of socks weighing just 20 grams.

Saddle – Tune saddle

The Tune saddle at 83 grams is definitely less than your average saddle. But, perhaps not the best. It has quite a bit of flex (which makes it comfortable, but I’m worried about power loss from a flexy saddle.

AX lightness saddle

Despite having an 83 gram saddle with fabric cut off. I still couldn’t resist an even lighter saddle. This AX Lightness Sprint saddle is a mere 69 grams. On the positive side, I do find it very comfortable for a thin sliver of carbon fibre, and have ridden on it all year, including 5 hour + rides.

Single chainring

For most hill climbs, you don’t need an outer 53 ring. If I do need a 53 ring for climbs like Long Hill, I’m probably on TT bike anyway.

The big temptation is take take off the front dérailleur too – it doesn’t do anything with only one chainring. But – and this is a big but –  Do you want to take the 5-10 % risk of your chain falling off for the sake of another 100 grams? Even the keenest weight weenie knows that saving 100 grams isn’t much use, if you don’t have a chain to pedal. It can happen, and usually when you least want it to.

They do make Narrow / wide single chainring – with deeper teeth to prevent chain jumping off. This is often geared at the Cyclo Cross market. Unfortunately, I couldn’t find any ‘narrow/wide’ chanrings compatible with four bolt Shimano Dura Ace 9000. I’ve got a chain catcher, but it’s not very good.

Chopping off the end of handlebars

I took a long time to work up the courage to buy an expensive set of handlebars just to be able to cut off the drops. But, this year, I’ve taken the plunge and bought some Zipp Sl handlebars. Straight away I got out the hacksaw and cut them off. The problem with buying such a lightweight handlebar is that when you cut off the drops, you only save a measly 50 grams. Still it’s 50 grams of weight saving, and perhaps it will be a better position for pulling on the handlebars.

Within two days  after doing cutting this (in Oct 2014) my coach Gordon Wright said I looked good climbing on my drops and I should try to do the whole climb on drops. I’ve never used them in a race yet. So it has to go down as the worst marginal gain I’ve tried.

Shortening the chain

12 grams from an Ultegra chain

With taking off the outer chain ring, I realised I could shorten the chain – saving weight and improving chain tension. Unfortunately, in my zeal to save weight, I took out five links and it became too short. I couldn’t use it because the rear dérailleur would have groaned in the biggest sprocket. I had to put some links back in. But, using a multi-tool chain splitter I managed to damage the chain. After using once up Leith Hill, I had to throw away and start again with a new chain. I think it has about 2 links less than usual, weight saving 12 grams.

Cost – more than it should have done. Moral of the story – never do bike maintenance yourself!

Not charging your Di2 Front derailleur fully

My knowledge of physics is limited to the fact an apple on a tree will tend to fall downwards because of gravity. For Bec HC, I heard a top rider saved weight by not fully charging his Di2. Is this the ultimate marginal gain? Does electricity have weight?

I had to admit I searched ‘Does electricity have weight?‘

Google.com answered mysteriously:

Yes and no, but mostly no.

So there you go, a marginal gain, even if only theoretically possible.

Removing bar tape

Brake pads cut in half

Hill climbs are run under CTT rules. You do need two working brakes. For 2005, I found some worn down brakes and cut them in half. I don’t bother with this any-more. I just use normal brake blocks.

Vittoria Crono Time Trial tubular

Vittoria Crono – 700*22 – has a claimed weight – 165 gram. I use both on front and rear.

Until 2012, I used Continental Competition in hill climbs, just because they were what I used for time trials. Continental Competition at 240 grams are a good workhorse, but not designed for hill climbs. I was throwing away 180 grams of rotational weight because I was riding nice thick puncture proof tubulars. On the positive side, I never punctured in a race or warming up.

I also bought a Vittoria Pista EV (track tub) which I only dared to use once (in 2014 national HC) It is 140 grams. It was an expensive 3 minutes.

Wheels

Zipp 202 Rear – 604 grams total: (rear Zipp – I got for £750). Expensive, but a good solid wheel, lightweight and strong.

Lightweight front

Lightweight wheel with Tune hub and AX lightness wheels – weight of wheel 345 grams (without tub). This wheel is really light, you can pick up with your little finger. Sometimes you test equipment and you can’t tell the difference, but replace a training wheel with a light wheel and you do notice the difference

Skewers Tune DC14

I bought a pair of lightweight skewers when I started hill climbing back in 2004. 11 years on, and technology has improved. My old pair were 55grams, so I looked around for some others. I nearly bought some U20 skewers for £163 at 21grams. But, right at the last minute – I thought I’m not spending £163 on a pair of wheel skewers – that’s obscene. Instead I bought some Tune DC14 for £93 – 35 grams. This was a rare failure of the marginal gain / spend money world. Buying the second best is always dangerous, because it gnaws away at you that you could have bought something better. Then one day, you may end up buying the most expensive after all – and having the second most expensive as well!

My tested weight was 35 grams

Smaller shoe size – Bont Zero

This is the ultimate marginal gain, which proves you are utterly bonkers. Buy a pair of shoes which is slightly too small, so you spend the whole season with squashed feet. But, on the positive side, you have saved the extra weight of a shoe which is o.5 sizes smaller than a good fitting size.

It wasn’t entirely intentional. See: review: Bont zero

Things you can pull off bike

I was cleaning bike the other day, and I realised this power tap plastic thing was unnecessary and could be pulled off bike. 4 grams in the bag. I will have to put some sellotape on hole in frame – so water doesn’t get in and negate the weight loss!

Removing stem cap

The bike

Trek Emonda on Trooper Lane

Amidst all these marginal gains. I suppose the most important is the bike and frame you start off with. The Emonda is a good start

Why Do People Say Weight off Your Wheels Counts Double?

I think the reason  is to do with acceleration and the fact the top of your wheel travels twice as fast as your bicycle (Don’t quite understand this, obviously I didn’t pay any attention in GCSE Physics and had to google whether electricity has weight). To accelerate, the energy taken to push the wheel is greater than for the bike. Once you have maintained a constant speed, then the weight of your bike and wheels count for the same. But, if you slow down and then accelerate, the energy to move the mass of your wheels is greater than for the bike.

Failed weight saving

Jim Henderson told me he spent one hill climb season weighing up whether he should risk riding with 4 chainring bolts rather than the more traditional five. He knew he could probably get away with 4, but in the end – he played it safe. I know a top rider who did 2006 Nat HC, and his chain come off mid race.

I once bought an AX lightness stem (26.9) because it was super light weight. But, didn’t realise it was the old size (which is quite rare these days. This meant to use it, I had to get a standard handlebar, but I’d run out of money for AX lightness handlebar, so I got some other model which was 27.0 – the resulting combination tended to slip because of that 0.1mm difference – losing power.  I ended up selling both on ebay for a loss.

Drillium – drilling holes

You can’t mention marginal gains on a hill climb bike, without a nod to the art of drillium. Carbon fibre has diminished this avenue of weight saving. But, in the 60s and 70s, everyone was drilling holes in bits of equipment to save weight. The holes probably made you slower in time trials, but helped very marginally in hill climbs.

Weight and speed

A lighter bike is not necessarily faster. Rigidity and power can make more difference. As can aerodynamics. For example, I wish I’d ridden a heavier TT bike in 2011.

Fortunately or unfortunately, there is more to hill climbing that getting a lighter bike. When I won the national championship in 2013 – it was the only year in my whole career where I spent nothing on making a lighter bike. (in fact it was heavier (6.0kg) than the one I rode on Rake in 2012 and that year, I even made a profit from selling an AX lightness stem!)

• Hill climb technique

The Newbury R.C. hill climb on Walbury hill was the first time the club had made the climb an ‘open’ event. But, it still felt like the atmosphere of a local club event. Newbury CC were out in force with 30+ entries from the promoting club. It meant another good start sheet with 70 riders, including quite a few juniors and juveniles. When I got into hill climbing a few years ago, it was quite common to have entries of 10-20 people – entries were so low, you kind of thought hill climbs were a real ‘specialist’ / ‘nutcase’ type of cycling. But, in the past couple of years, entries have really been on the up. Perhaps it’s a combination of British cycling success, and the popularity of GPS tools like strava segments. These days, courtesy of Strava – everyone’s become hill climber;  so I guess it’s only natural to make the next step from virtual competition to real competition.

It was a good friendly event, with enthusiastic support. If you like chasing Strava records on your own, you will be surprised at how much more fun it is doing it with other people.

After just one short – but intense – effort yesterday at Leith Hill, I was relatively fresh, and I had the luxury of a short 45 minutes drive. It is one of the closest hill climbs to Oxford, and saves a drive up the M6. Although it’s fairly close, I haven’t been on these roads before, so I took an opportunity to ride Walbury hill, just before the race got underway. I did take some tribars after looking at the profile of climb. But, after a warm up on the climb I thought there was no point in using them.

There is a 7% gradient to start off with, then a very shallow gradient of just a couple of percent. As you turn left near the top, it starts to get properly steep, giving a hard test for the last minute or so to the top of the hill. The average gradient for the hill is 5.5%

Perhaps because of the shallow gradient, I again didn’t go too hard in the middle section, but as the hill became steeper I tried to give it everything. Unfortunately, my gears have been playing up. I had to put on a new chain last night, but it still gave a horrible change at the start of the steep bit – a bit of a knock to the momentum, but fortunately it stayed in place for the remainder. Just when you crested the hill – there was still a short flat bit before the line. I stopped the clock in 3.55 – beating the course record set by James Wilson VC St Raphael CC (4.09) just a few minutes before.

It was another great day for a hill climb. The weather was perfect and the view from the top of Walbury hill excellent. There was a good crowd of spectators at the top. I even got interviewed by a local radio station – I hope I was able to say something useful.

There was an excellent prize list with sponsorship from a variety of sources, including Newbury News, which gave a good first prize. I also won a copy of Mountain High for breaking the course record. I must admit to being doubly relieved not to end up with the Lantern Rouge prize. As a strict vegetarian I think I would have struggled to spend a £20 voucher for a local butchers.But, I don’t think I was ever favourite for Lantern Rouge. Maryka Sennemya (Kingston Wheelers) was first lady so it was the same result as yesterday.

It was good to chat to the Newbury locals, and great to see so much enthusiasm for a hill climb.

After the race I put on training wheels and went up Walbury hill a steeper way and over the top down into Hampshire. There was the longest gradual descent of 1% I’ve ever come across.

Combe Gibbet #25

A bit of an unexpected bonus was riding Combe Gibbet. I rode it before the race warming up and after the race. I didn’t realise it was one of the 100 climbs, until I got home. 100 Climbs

Kingston Wheelers hill climb on Leith hill.

It was  another balmy September day. 22+ degrees as I was warming up on the turbo. It was almost too hot and sweaty for the turbo – not usually a major problem of the hill climb season. As I was driving to Forest Green, I saw lots of cyclo sportive riders having a good time cycling up the Surrey hills. There was part of me slightly jealous of the sportive riders – it was definitely a good day for a five hour steady ride, instead I was facing the timekeeper and three and half minutes of hill climb hell.

The day before, I put on a new chain, I tried to take off outer chain ring, but you seem to need two of those hexaganol wrench things so I was unable to do it. The new chain wasn’t so good job either. Firstly, I made it too short, then I had to put some links back on. It was working well on training wheel, but when I put Zipp 202 racing wheel on, shortly before the start, it started to jump a little. I don’t know why because it has a fairly new cassette. Still the bike was quite stripped down and light for the time keeper. I saw my minute man go off with great gusto. He probably set off faster than I planned to start.

This is the third time I’ve done Leith hill climb. Previous times were 2012 (3.33), 2013 (3.33.1)

• Distance 0.9mi
• Avg Grade 8.0%
• Max Gradient – 18%
• Height gain 115m

I took the race quite seriously – because it’s a similar distance to the national on Pea Royd Lane, if not quite as steep.

I set off fairly steady, and seemed to hold back for quite a while. Then as you turn left the gradient increases a little and it was time to increase the effort. Round the corner there was a great crowd of people cheering you on. I just saw a sea of white and blue Kingston Wheelers jerseys.

By this point it was getting a bit of a blur, I was able to hold quite a good pace and speed all the way to the line. As I crossed the line I had quite a bit of momentum – it was here after the finish line, I caught my minute and two minute men who were rolling slowly over the line. I thought I hadn’t paced it so well, I wasn’t as dead as last year. I felt I should have tried to go faster earlier. I also thought the course record was 3.23 for some reason.

Anyway back at the HQ I found I had taken six seconds off course record with a 3.27. From being slightly miffed at not getting the pacing right, I was quite pleased. It was definitely a quick day – no tailwind, just warm and muggy which seemed to make it fast. It would have been really interesting to have power meter from last year. I paced it a bit differently, but perhaps this year was better strategy, I don’t know. Still the finish seemed to come along a bit quicker than expected.

Compared to last year, at half way point I was 8 seconds slower. In the last half I must have been 14 seconds quicker. Quite a different race.

Anyway it was a great event, and good to see a strong club like Kingston Wheelers encouraging so many to take part in a relatively minority cycling discipline. Markya Semenya (Kingston Wheelers) was first lady, so there were two national hill climb champions winning in the same race – not so common, I imagine – we both had a national jersey, which was good.

There were some good times from quite a few people, and quite a few novices to hill climbs having a go for first time.

Afterwards I rode up Coldharbour hill.
