Is rust inevitable

jamienorton

so just cleaned my bike after being caked in mud in the monsoon like conditions yesterday (great fun btw) and noticed a small amount of rusting on the chain and teeth, is it unavoidable and will it start to affect shifting eventually, i use finish line wet lube btw.

It generally wipes off - its probably just surface rust. Its avoidable if you keep the drivetrain properly lubed and dry it / spray with gt85 / tf2 after its been wet to repel the water and avoid the rusting.

Clean with water + degreaser > wipe dryish > spray GT85 or WD40 > wipe clean > chain lube.

No, keep WD40 away from your chain. In fact keep it away from your bike.

Chain lubes are designed to bond to clean, grease free metal surfaces not WD40 or GT85.

Glad we all agree on that..............could have turned into a long thread.

I use wd40/gt85 on all our bikes, sprayed lightly on derailers after a wash (using the straw so it doesn't spray everywhere).

I also use it on chains after a wash, as it helps disperse water, a quick wipe to get most of it off, then run a bit of lube on the chain.

I have found that the wd40/gt85 seems to carry the lube into the chain internals quicker, the wd40 will evaporate leaving the lube where it is needed. I use less lube, the chains stay cleaner and don't rust.

wd 40 is the work of the devil . it destroys the seals around forks and bearings .

gt85 is good for dry weather and cables

Granted. not good for rubber.

Yes, but I was clearly not suggesting leaving it on the chain or using it instead of a lubricant, simply using it for its intended purpose: getting the water out of a chain.
