Q & A


XX1 Crank. King Of The Ring.

When you reach this level, the best is no longer good enough, you want better. The XX1 crank is that superlative.

Each X-Sync chain ring fits a single, universal spider - allowing you to change rings without the hassle of removing the ultra-light carbon crank arms.


Beside serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.


GXP's Gutter seal design cuts friction, durability and weight - improving both feel and performance.

XX1 Chainrings - Available Separately

Developed for maximum chain control, each tooth's thickness is precisely CNC-machined to support the chain's inner and outer links perfectly. Creating a stronger contact point, more drive and more fun!

NB: Chainrings and GXP/BB30 Cups Not Included - Cranks Only

To determine which Q-factor (width) you require, you need to measure up your frame.  The Q156 is 64.5mm and the Q168 is 70.5mm from centre of frame to the inside of the end of each crank (where it would hit the chainstay if too narrow).  To get a good idea, double this measurement (129mm Q156.  141mm Q168) and measure the width of your chainstays, outside to outside, to see if there is clearance.  You'd need to leave around 5mm+ on each side for crank clearance.
