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.

Purple values are especially important to compare against your current crankset when determining compatibility. 2XR Cranks are designed to fit similar to many existing cranks, but not all setups are the same.
