At A Glance
Tired of creaky or clumsy adjustable cranks that don’t offer the lengths you need?
The 2XR FIT Crankset is our vision for what a variable length crank can be: simple, robust, and a range of useful crank lengths.
Made for professional fitters, studios, physical therapy (PT), medical offices and crank length enthusiasts.
Use them on a size-cycle, fit-bike, or outdoors on a real bike.
These cranks are designed for real world use and offer up the same quality and modularity and sizes as the original 2XR Crankset.
2XR Fit Crank Features
6 Crank Lengths: 175, 165, 155, 145, 135, 100mm
Covers a wide range of rider size, riding styles and physical peculiarities.
5 Q-Factors: 150, 156, 168, 183, 201mm for road, gravel, mountain and fat bikes.
Easily Swappable: Quickly change crank length simply by removing/installing the pedals (no proprietary tools)
Swap Q-Factors (spindles) on a fit-bike in a few minutes using only a 5mm allen wrench.
30mm Diameter Spindle: Common size that fits most bikes and size cycles. Note: most size-cycles use a square taper BB/crank so you may need a new 30mm BB when upgrading to 2XR FIT Crank.
Made in USA: designed, CNC machined and finished in Minnesota.
