Welcome to the new and improved Proflex / K2 Tech Forum!
Welcome! I've just done a similar thing and built up my OZ as a modern build. The OZ/4500 takes the same size BB as the 957. I used a Shimano XT770 Hollow Tech 2 crank. It comes with spacers for different width fitments. Here it is again Nice collection by the way!Chris
Cheers Col . I laughed for two reasons. One is that I have been guilty of criticising Proflexs in the past for not having vector/Crosslinks, so it's seems only fair that my bike should be criticised now. Two because he has totally missed the point of this thread and why I built my bike. The thread is about building up a 957 with modern bits as was the reason behind my OZ. I build bikes to ride and not just look at, so having the luxury of four other Proflexs with vector/crosslink, I think this one will pass. Chris
I am now only waiting on XTR v-brakes and XT levers, and I will have everything to complete the bike, except maybe cables/housing. I was trying to decide on a tire, and came across Velociraptors, perfect! I still run Dart/Smokes on my Cdale.After a good polishing of the frame, I can start assembling.
