Notice this every single time since the weather has turned.
after some mud, when the whole driveline is covered in clay/chalk/dog eggs i get a knocking sensation...
First time it happened i thought i had a loose pedal, dodgy BB or my casette was loose on the flywheel.
turns out, after a few minutes of riding it sorts itself out again, and when the bike is clean, its all fine...
wondering is its worse when the jockey wheels are all built up with crap? and maybe the chain kinda hops over them more? anyway, if i can prevent it that would be awesome, driveline as follows:
snail 32T oval
Sunrace CSMX80 11-50 cassette
KMC 11 speed chain
XT 8000 derailleur (clutch on)
Any thoughts on what/why this happens and ideas to prevent? or just get on with it 😛
just get on with it
or buy a gearbox
Is it worse in some gears?
I recon the angle of the chain onto my snail narrow wide ring causes grinding as the chain goes onto every "wide" tooth when it's muddy and I am at either end of the cassette.
I've never used another narrow wide ring enough to know if it's a snail "thing"
good point, i only notice it in the easier gears.... but thats after descending and having some time to pedal back up before the next
