Thick thin ring on a hardtail – chain device necessary?
I have a thick thin chainring with a clutch mech but sometimes forget to switch the clutch on after taking the wheel out. I’ve not dropped the chain in six months that I’ve had thus system.Posted 3 years ago
How much riding have you put into the chaining? I guess they’re going to wear Out eventually.
Took the only spacer off driveside as chain was dropping all the time. Have removed one link at a time until I can’t remove any more. Dropping has reduced along the way until now it’s just once a ride at most.
Don’t have a clutch mech (bought a new XT shortly before the clutch ones started coming out). Same setup transferred over from FS and it never dropped on that bike.
Suspect ring could be wearing now. It’s about a year old (a Race Face).Posted 3 years agorobinlaidlawMember

Also, I strongly suspect its chain wear not ring wear that is the problem. The ring doesn’t actually grip the chain, it can’t, it’d chain suck something rotten if it did. All it does is make it hard for the chain to swing far enough sideways to drop off the side in the length of a single link, which means that even when the chain bounces, it has to land back on the ring as it’s lined up. If the chain gets worn and more flexible sideways, it’ll be easier for it to move over and fall off.
Chain has got plenty of life in it (nowhere near 0.75 wear indicator yet). Suspect I’ll invest in a clutch mech at some stage soon – seems to make even more sense on a HT.
Are they proven yet? Heard one or two reliability issues with the tension wearing out quicker than the normal life of a mech.Posted 3 years agorobinlaidlawMember

Oh, I’m sure there is, I simply mean that I don’t believe it’s predominantly the ring wear that causes the drop in performance. I could be wrong though.Posted 3 years ago
And yes, there’s been some issues with clutches breaking but in terms of wear, they can be tightened up on both brands.
With no chain growth from suspension action further tensioning the chain, I’m finding my thick thin ring drops the chain on my hardtail, even with the shortest chain length I’m able to run.
Is this the case generally, or could it be down to the fact my ring has worn?
Do hardtailers run at least an XC chain device all the time? Is there then, no need for a thick thin ring on a HT?Posted 3 years agoNobeerinthefridgeSubscriber
10 months now, and dropped the chain twice, both in the same really manky ride, about 2 months ago. Ring is starting to wear, particularly noticeable on the thin teeth, but still holding up great.
I reckon forty quid for 10 months solid use so far is not bad. Raceface 32T btw.Posted 3 years ago
