The braze on tab held on by 3 rivets is loose on my Felt F1 frame. There's enough movement where it pulls my front derailleur into my crankset when I try to shift into the big ring. Is there a fix for this or is the frame trashed? I bought it off ebay a year ago and therefore I know a warranty will not cover it, but I'd much rather pay to have it fix then spend a lot more to have to buy a new frame. Does anyone have any thoughts if a LBS will be able to fix this?
