I recently purchased a replacement set of cranks (2004 Campagnolo Centaur) on ebay and question if they are compatible with my existing bottom bracket (Shimano, early 90's).
Both use a square taper spindle, but the new cranks only slide partway onto the spindle. The bearing suface inside the cranks is about 3/4 inch, but the spindle only slides in about half an inch.
The old cranks slid pretty much all the way around the spindle.
Should I be concerned about using these two together? Should I get a replacement bb?
Thanks for the input.
