I currently have five different chain lubes on my shelf at the moment. I’m not sure why I have accumulated so many. But, it gives me something to review.
GT-85
You will find GT-85 in many bike shops and is one of the most popular thin water-displacers. It is excellent as a water displacer and thin lubricant. It is easy to spray on and will prevent rust. After a wet ride, I will give a good spray and spin the chain, allowing water to come off. GT-85 is quite economical, a large 400ml can last quite a long time. However, because it is quite thin, it doesn’t give too much ‘lube’ to chains and as a result, if you rely on it to lube your chain, you can wear through chains quite quick.
It is best not to use this as a lube, but it is good to have around for other purposes.
GT-85 is one of the best sprays for brakes and cables – It helps resist rust, keeps things moving and won’t attract too much dirt. It doesn’t leave much of a residue.
Also, GT-85 makes an excellent way to clean and polish your frame, spray some on, and give a quick polish. You will be pleasantly surprised at how clean it may get. Also, if you do spray on the bike and components, it makes it easier to clean next time.
Great for cleaning, water displacing and using on components, but don’t rely on for overall lubrication.

TF2 Lubricant
I bought this from Reg Taylor when they recommended as a better chain lube than GT-85 (which I was using at the time). It is a bit denser and stays on the chain well, making it better for long-distance cycling. The added ingredient of Teflon helps to prevent the accumulation of dirt. You can also get this lubricant in non spray form. It is a good all-rounder, if you wanted to get just one chain lube TF2 would fit many of your needs.
I was using this over a wet winter in England, and to be honest, it required quite frequent reapplications. The chain on my commuting bike would often get dry and rusty – despite using chain. On training bike, the chain also ended up quite dry and a little noisy. I’ve seen people claim one lube can last 400 miles, I couldn’t verify this over winter. I would have been better off with a heavier ‘wet ride’ chainlube. On the positive side the chain remains clean and easy to handle.
It will be fine for commuting bike except during very wet winter months.
