On the weekend developed a problem after I shifted down to the small ring on the front of my road bike (SRAM Rival groupset). I couldn't shift the FD back into the bigger ring.
When I push the lever, the FD moves the chain onto the big ring. If I hold the lever in place and keep pedalling, the chain will 'catch' the teeth of the front ring whilst I am still pedaling. However, if I release the lever, the FD will then travel back to the small ring position. It is almost as if the FD isn't 'clicking' into that bigger ring position.
I tried loosening off the nut holding the cable in place, pulling the cable tight then retightening but still have the same issue.
Any suggestions on how to fix this?
