So I recently purchased a compact crankset, but had trouble upshifting. The HL screw was as loose as possible so it was a reach issue. I'd already lowered the FD to the right height angle. In a moment of frustration I tried to crank up the cable tension to try and get it to shift up, and stripped the FD nut when tightening the cable clamp bolt too hard
I presume my bottom bracket is too long. Is that a fair assumption? Anyway, i was wondering if I shimmed on a 31.8 onto my 28.6 seat tube would that enable the FD to reach further.
Your thoughts would be appreciated
