Which 5DEV spindle do I Need?

5DEV offers Standard Boost Cranks with 68/73mm BB and 2 spindle sizes, as well as SuperBoost+ spindles for specific crank lengths.

For SRAM Cranks on your bike, you will require the 29mm spindle option.

If you have 30mm Bottom Brackets, you will need the 30mm spindle, as this is a standard bearing size commonly used in aftermarket BBs such as CaneCreek, Chris King, EuroBearing, Kogel, etc.

For Shimano Cranks with a 24mm BB, you must first determine if your BB is a Press Fit or a BSA Style (Threaded). Following this, you will need to replace your BB with either a SRAM DUB or an aftermarket brand with 30mm Bearings.

The same applies if you have SuperBoost+ - determine if you have a SRAM or 30mm BB for compatibility.
