I've had my road bike with SRAM Red for 3 months. All was well till Thursday when it began over shifting and dropping chain off cranks. I've followed the instructions and I can't for the life of me get it to work. Either doesn't shift up or when it does it over shifts. I'm afraid of expensive damage at this rate. Any tips?

i run sram red, the issue is the front mech. its got a ti cage. great for weight but flexy so has o be set up perfectly otherwise it is prone to over/under shifting. sounds odd but i downgraded to the force front mech which is steel and no issues (also sold the red front mech on ebay for silly money) i heard the pros do the same by the way as in run force front mechs but cannot verify this

Cheers. Going to get the bike looked at by a qualified mechanic, I've exhausted my skills now.

3 months sounds like too short a time frame, but worn chainrings are another reason why SRAM overshifts, in my experience

Thanks, I agree it's a short time will find out tomorrow. Frustrating taking it to workshop as I usually do my own spannering!
