Reducer to use 24mm cranks on Dub BBs.
This allows you to use your Shimano Hollowtech II cranks on Dub bottom brackets without changing BBs. Why? because Dub spindles are stupid and the Shimano 24mm spindle is better. Why? because of science, and bearings, and tolerances, and standardized spindle width, and ease of maintenance; but most importantly less proprietary bullish!t.
Just print the parts at 100% infill to reduce squish, and slide the spindle through. Will work half ass on GXP cranks, because that spindle has 2 diameters and is a disaster. So you will have to modify one reducer for the smaller side of the spindle.
If you are going to pound the pedals I recommend you print this on something substantial like nylon.
