- Chain riding up on casette, only 100 miles old!
Chain is riding up on casette and shifting inconsistently it’s winding me right up! I’ve tried adjusting the mech till I’m blue in the face. Tried taking the chain off and degreasing and checking for stiff links and twists of which there was none. Changed the mech hanger. Cleaned and lubed the mech. Swore at it, etc. It always seems to end up riding up on the top 2 rings, and also doesnt shift up or down well in the mid range. The cables are about 3 or 4 10 mile rides old and seem to move in and out fine.

Any clues?Posted 6 years agomrgollMember
Are the jockey wheels OK?
Is the chain correctly routed around them?
Are you sure the cable outer is not split or damaged?
Is the inner not freyed somewhere?
How much gump/debris is there floating around inside the shifter itself?
Are you sure the chain has zero defects and is the correct size (8/9/10 speed)?
I have seen similar funny side effects from bent hangar which looked perfectly straight… After inspecting and double-checking everything – get somebody with fresh eyes to look at it (LBS?).Posted 6 years ago
I think it must be the chain, it got jammed in the front rings on the ride, it must have twisted it. It didn’t look twisted when I took it off to inspect it though.
The jockey wheels are all moving freely as is the cable. Might have a look inside the shifter itself, hadn’t really thought of that.Posted 6 years agojamescoMember
My mate has reverse action on a Marin doing exactly the same, last week on trails I thought hanger was bent so we pulled it a bit and wound the low screw so he lost bottom gear and it was better , but LBS can’t cure it , I wonder if they realise its reverse action mech? We might just have to spend some time on it instead of ride an’ bodge.Posted 6 years agokarl1824Member
Try checking the stop screw which sets your rear mech tension/position front to rear.Posted 6 years ago
I have know this either be snapped off or badly adjusted, cuasing similar symptom to that which you describe. Should be able to spot as the top jockey wheel will look too far forward.
Think it might have been a few things, but the main part of it is the complicated cable routing on the lapierre and the weak spring on the SLX. I had a cable oiler in there so I replaced the whole outer and removed that and it seems to have solved it. I did take the shifter off my 224 and I have to say the saint stuff and the cable routing on the 224 made the SLX equipped lapierre look stupid and annoying.Posted 6 years ago
But the problem still exists to an extent, even with a brand new cable. The cable routing just has too many twists and turns. I’ve tried to leave it looser this time around the bottom bracket area but the cable still doesn’t move completely freely through the outer. Especially in comparison to the straight routing on the 224.Posted 6 years ago
