cross bb...
I have a quattro assi cross frame that was built as a proto. it was
designed for mtb cranks. But I run a road crank, with a 44t single chainring setup (44t on the inner, guard on the outer, seatpost mounted guide for the inside). All was good wehn I had a DA (square taper) crank on it, using a phil bb 119mm TI bb with +4mm drive side. This year, I can't stand to not have the data, and want to run my SRM Pro on the cross bike. It uses an octalink shimano bb. Noticing that the ultagra bb is a 110 or 118, is the 118's additional length symetric? or is it mostly on the drive side (I hope)? thanks, g |

Probably the best option for your application would be a 112.5 XTR BB. http://harriscyclery.net/site/page.c...=49&SKU=CR0973 Sheldon "Answers" Brown +------------------------------------------+ | Do, or do not.
