- Chain slip with new drivetrain. Anyone encountered this?
Whilst riding home tonight I managed to get thrown off my bike twice, thanks to sudden chainslip.
The cassette, chain and cranks are barely a month old and haven’t covered more than 150 miles, plus the chain slip occurred in both the large and middle chainrings, so I don’t think it’s the cranks. It seems to happen in one specific cog though.
What’s the prognosis, is it (another) new chain and cassette?Posted 5 years agodeadkennySubscriber
Cassette lockring done up to proper torque, or has it come undone and cogs are now loose? Usually needs about 30 to 40 Nm, but will say on the lockring. Basically needs to be done up quite tight.
14t I guess is the second or third smallest so at the top of the stack. I’ve had issues with an incompatibility with a certain cassette with a freehub where the top cogs don’t even slot onto the freehub splines and just rotate round until the lockring is fully tight.
Also, is it slipping on the cog or is it jumping or trying to jump off or onto it? Can seem like it’s slipping. If the latter it’s likely an indexing issue.Posted 5 years ago
It’s slipping on the cog – I’ve reset the indexing twice and the problem won’t go away, the hub itself is a Hope Pro 2, which has started making some noise, so I assume the freehub bearings could be ronnied in which case I’ve my suspect. I’m going to do a wheel swap today with another set of Pro2 wheels and that’ll hopefully give me my answer.Posted 5 years ago
