SRAM SPLINE chainring interface, 24mm crank spindle diameter (Shimano style). To see if this will work on your particular bike, we suggest identifying the bottom bracket Wheels Mfg 24mm Crank Bottom Bracket to see if these will fit your specific application or contact [email protected] directly. When you contact Wheelsmfg.com, tell them you need a 24mm (Shimano style) bottom bracket for your application.
Our direct mount crank arms system typically drops 150 grams or more off a traditional setup with a steel spindle, and our shorter sizes really allow for a dialed in ride quality - especially for shorter riders! These crank arms fit a 68/73mm bottom bracket shell, 168mm Q-Factor.
If you are buying these for a boost (148mm) spaced bike, our friends at Wolf Tooth offer nice 3mm offset chainrings for a 52mm chainline here - Direct Mount Chainrings for SRAM Cranks – Wolf Tooth Components.
DOES NOT INCLUDE CHAINRING OR BOTTOM BRACKET! If you need arms, chainring and bottom bracket, select our complete crankset option.Â

I love my short cranks! Comfy with my 28 inseam. Just swapped my cues 1x cranks and got a wolf tooth 42t direct mount chainring with 6mm offset which made it perfect to get my ~49-50mm chainline. Plug and play.

I bought these for myself, a 5 ft tall woman. Compared to my 170 mm cranks these are so much more comfortable! I’ve used them on a few rides and I’ve been a lot faster on the uphill already, and noticed less bouncing every time I pedal.
I bought them with the recommended Wolftooth chainring to fit my existing chainline. Super easy to install with the included instructions.
