- Chainring & cassette wear – when?
What is the indicator of a chainring or cassette being worn? Chains are easy, I have a little guage by Par, but what am I looking for on the sprockets?
Currently the teeth are asymmetric and worn a little pointy on the granny ring, cassette looks more even. Surprized if it is worn out as all fitted new with a fresh chain, and the chain is still within the .75 wear limit.

Sailor, in 6 weeks of using rock n roll extreme dry lube, my chain went from well below 0.75 to 1.0.
While the dry lubes definitely keeps the exterior of the chain looking clean, my limited evidence suggests that its not that good as an actual chain lube.
Thinking about it, since the chain roller is a metal on metal drag, anything that sets up hard will be ground out/off the bearing surfaces fairly quickly – Surely one needs something with a low enough viscosity to flow back onto the metal after that roller has born the load?Posted 8 years ago
Science officer – hard to explain – a bit softer than candlewax, harder than ordinary grease similar to shoe polish / wax furniture polish???
On friday I did a 35 mile wet ride on gravel surfaces which normally strips lube out – the chains were still well lubed afterwards.
I am still measuring wear on the chains but it appears much less than previously and the lube lasts hundreds of miles rather than tens of miles
I am really impressed with itPosted 8 years ago
Science officer – no need – the molten wax does it for you. – the chains are fairly clean anyway as muck does not stick to the wax. When you put them into the bath of molten wax the stuff going into the spaces forces any muck out – the bottom of the tin gets all gritty but it does not stay in suspension in the wax.
