While I was waiting for a reply from Middleburn, I thought I would post my question here to see if anyone has this setup.
I need to know the best isis bb spindle length for Middleburn Duo cranks (29/42) with a bb shell width 68mm (clamp front der. not e-type). If needed, my rear cassette and der. is SRAM 11-32 with X.O medium cage.
