Chain problem

Paul Hunter

Recommended Posts

Hi All


Please could somebody explain to me why my chain seems to come off the big chain ring especially over rocky sections. This has become a pain now. Do I just need to adjust my FD?


Thanks in advance

I've even had a quick link disconnect on a rough downhill before but that happens once in 500 000km I guess ;-)


It's all about front der adjustment. What's great about SRAM gripshift is that you can fine tune the front der position and what I like to do on rough downhills where I won't pedal is tune the der one click down should be nearly rubbing the chain and the chain won't rattle off of the big ring.


Also change to #3 or #4 at the back to further increase the chain tension...


Or just get a clutch rear mech.


Also check how big the gap is between the front der cage and big chainring... cage should be 2-3mm higher than big ring.
