Ok I am a little confused and need a little help. I am rebuilding a mid 80's Pinarello CX bike with Italian BB threading. I have found a BB. It is a Shimano Octalink V2 with the 9MM spline grooves. I ordered a Ritchey crank that is octalink compatable. However it does not say V1 or V2 - does it matter? Are V1 and V2 crank compatablity interchangable?
