CRANK FEATURES

- Aerodynamically designed to reduce turbulence and separation around the spider, chainring and crankarm.
- 144mm BCD for track and road with 6mm thick chainrings, improving power transfer by eliminating any chainring flex.

- Adjustable crankarm length between 145-160mm and 160-175mm at 2.5mm increments for each crank size. Also available in fixed crank length.

- Optional - track option comes with low friction additive infused 1/8” track chainring in 58/59/60/61/62/63/64/65/66T.
- Stepped chainring design keeps the chain outer plates flush with the chainring to reduce air-flow separation with paired with our crank specific chainrings.

- 1x retention bolt and washer

NOTE

Standard 58t or larger 144BCD 5 bolt chainrings can be used with the crank. If you want to utilise this option please select "N/A" under chainring options. We recommend the Pyramid 144BCD 5 bolt track and 1x chainrings as compatible options (both available through WattShop). However it is optimal to have a Cratus specific chainring.

This crank is only compatible with 58T or larger chainrings and it is currently single ring only design. Chainrings can be ordered separately.
