Post by: Gary72 on October 16, 2010, 10:31 PM: I had this with some Redline cranks. I put a allen bolt in the end and spun it on a drill and filed it down to fit 19mm bearings both sides >:D

Post by: Spen69 on November 05, 2010, 11:45 PM: Russ, if you have a set of 20mm bearings in USA cups then sell them to me bud or I'll buy you a 19mm USA set and swap you.

I need 20mm and can't find them about, but plenty of places sell the 19mm standard sort, like this fella :daumenhoch:
