68 x??? Shimano Octalink. Anyone know the correct spindle length? LX level crankset and FD. 113 is way too narrow and a 121 rubs the FD badly in the big ring or won't drop to the granny ring. My 2000 SL worked great with a 113. This one has me scratching my head. Found nothing at the SC website and LBS was no help when I was there. I can get a 118mm but would like another opinion. Would appreciate any help.
