What bars have you used and liked on the felt ia? I have hydralic brakes and the di2 single buttons. I just tried to swap to a alpha one, i haven't seen it yet but the mechanic said the bento won't fit and he crushed the base bar clamping the brakes to the bar...
I probably should have left the stock one on, it just seemed cheap...
