5DEV Offers Standard Boost Cranks 68/73mm BB with 2 Spindle Sizes and SuperBoost+ Spindles for select crank lengths.
- SRAM DUB 29mm (28.99mm) If you have SRAM Cranks on your bike, you need the 29mm spindle option.
- 30mm Spindle for 30mm Bottom Brackets. 30mm is a standard bearing size, and most aftermarket BB’s use this size. CaneCreek, Chris King, EuroBearing, Kogel etc. If you have an aftermarket BB. It’s probably 30mm.
- Shimano: If you have Shimano Cranks, you have a 24mm BB from Shimano. You must determine if your BB is a Press Fit or a BSA Style (Threaded). Then you will need to replace your BB with either a SRAM DUB or an Aftermarket Brand with 30mm Bearings.
- If you have SuperBoost+ the same applies. Determine if you have SRAM or 30mm BB.
