LTD Custom shop cranks are only available in the sizes shown. They are limited production runs with limited quantities available. 5DEV's goal is to develop cranks that can be manufactured in a short period of time. Utilizing 5 Axis CNC machines, they can produce products in days vs months or years. These cranks are engineered for aggressive trail, enduro/park and DH style riding. Ideal for charging steep technical chunk, ripping laps at your local park, or sessioning your favorite jump line. The low profile crank arm reduces pedal strike during technical punchy climbs, allowing you to clean more sections of trail and get back up to take another lap with less effort.

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.
