• Last night my bike wouldn't shift to the larger cogs on the rear derailleur. I pulled the shifter apart this morning and the pawl (circled green) won't engage the ratchet. It looks like the spring (circled yellow) has broken. Is it fixable, or do I need a new brifter?

    Current brifter is Shimano RS 505, and I've had the bike since new for almost exactly 4 years. I know it's well out of warranty, but am a bit gutted if it's broken in a way I can't repair!

  • No idea if this would help for your situation, but I had a (older) Ultegra brifter that jammed while shifting to bigger cogs. The shifter felt mechanicaly blocked, so you couldn't 'flap' it to the left. I solved it by removing the shifter from the bar and tightening the allen key bolt on the back (where shifter meets bar) to remove a slight amount of play. Had the same problem on a R8000 Ultegra shifter, but that one lacked the allen key bolt on the back so no chance to adjust. Sent in for waranty at LBS...
