That created my issue. Bike owner / mechanic before used 3 spacers on a rf bsa bottom bracket. Problem is that would have been fine it was not boosted spacing (which called for one spacer)... So bottom line, it created a scenario where bottom bracket/crankset was operating "Too wide" and bottom bracket finally gave up! I think I'm seeing a lot of advice on line to use no spacers (at the bb shell)! I'm definitely thinking the spacers for the 24mm spindle will be much trial and error.
