How many BB spacers on Shimano CUES conversion?

    Upgrading my Cannondale Quick 5 from a crap microshift to Shimano Cues via Chinese Amazon. Anyone know how many spacers to run on new shimano MT501 bottom bracket? Small and large on each side? Factory bb is 68 threaded going from the 2x to 1x Shimano cues crank.

    1. Every bike is different. I’d start with none. If you can’t shift or hit frame, add spacers til it’s good.

    2. Shimano is usually pretty good with this information. A quick google should be get you the information needed.

      Edit: didn’t see you said it’s a 68mm shell. That crank is probably designed around a 73mm bb shell so you’ll need 5mm ish of spacers, I usually split that between bb spacers and crank spindle spacers
