Hello,

A friend of mine has an old klein frame that he wants to put a new XTR gruppo on. However, the Klein's BB shell fits pressed in cartridge bearings. Are there press in cartridge bearings that will work with the integrated XTR spindle cranks?

Thanks,
Richard

The only BB spindles available for that frame (that I'm aware of) are the old square taper type.
He could install an old M900 XTR crank, but that's as close as he's going to get AFAIK.
