I'm considering upgrading my crankset on my tandem to new Shimano Ultegra. The rear wheel is 145 and
the chainstays are straight. I currently have a tapered BB UN72 68 X 122 with a Ritchey Logic
crankset. Will the octalink 118.5 Ultegra triple BB be wide enough for the cranks to clear the chain
stays? Thanks.
