For a Rene Herse double crank (46-30) on a trad’ish randonneur (130mm rear spacing, 700x32mm tire clearance + fenders, straight chainstays not curved)… what actual BB spindle lengths have people had success with? I’m aware of the RH charts… one chart suggests 110mm and the other chart suggests 107mm - so I’m more curious about actual experience ‘from the field’.
Origin of my inquiry… poor FD shifts (FSA/IRD “compact double”, I’ve tried them both)… either it throws my chain beyond the big ring and onto the crank arm… or I limit its travel and it won’t shift big at all. The narrow Q on the RH crank arm minimizes any experimentation with FD cage angle. And my cage sits just a mm or two above the big ring, akin to Shimano’s alignment sticker. So now I’m wondering if my 113mm spindle puts the FD cage too far out in its swing. I could easily fit a 110mm spindle, and probably 107mm based on eyeballing clearance to the chainstays. Maybe shorter spindles would improve FD throw/alignment? Thanks in advance for any thoughts on this wandering missive. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
