At A Glance
The 2XR Crankset was developed by framebuilder Matt Appleman to improve the interaction between body and bike.
Versatile and modular, these cranks offer up new fit options for a wide array of people and a full fleet of bikes.
100% Made in the USA. Designed and CNC machined in Minnesota out of high strength aluminum.
Why Crank Length Matters
The Key to a Better Bike
No other component controls so much of the riders motion. Your whole lower body constantly churning with every pedal stroke.
In search of optimizing fit, comfort and efficiency, Appleman’s approach to crank length challenges the archaic sizes commonly found.
After years of knee pain, Matt Appleman found shorter cranks vital to bike fit and has encouraged all his custom frame customers to ride appropriately sized cranks for the absolute best bike possible.

As a rule of thumb, use 20% of your inseam to find your crank length
Shorter Cranks for the Win and Comfort
- more aerodynamic position
- reduced pedal strike
- more comfortable
- less toe overlap
- better frame geometry
- less knee, hip and back pain
- reduce dead spot
What Cranks Work for My Bike?
Use ROAD SPINDLE + 110×5 SPIDER for road, gravel, CX type bikes or bikes with road drivetrains (like Ultegra, Force, Record, etc…)
Use as 1x or 2x chainring (1x use outside position).
For the track or fixie bikes, use the Road spindle with 144×5 Track spider.
Q-Factor = 150mm
Use ADVENTURE SPINDLE + 110×5 SPIDER if you’ve got a gravel bike using a widely spaced gravel or mountain drivetrain (like Shimano GRX or similar).
1x or 2x chainring compatible.
Use ADVENTURE SPINDLE + 104×4 SPIDER if you have a mountain bike that is designed for/accepts narrow Q-factor cranks. Measure your frame to ensure there’s enough clearance between the crank arms and chain stays.
Use the MOUNTAIN SPINDLE with a 104×4 SPIDER if you’ve got a mountain bike.
Mounting the chainring on the inner position provides standard/boost chain line while mounting on the outside position provides super-boost chain line.
Q-Factor = 168mm
Use the MID-FAT SPINDLE and 104×4 SPIDER if you’ve got a fat bike with a narrow q-factor (like the Otso Voytek or similar).
Mount the chainring on the outer position.
For some super-boost bikes, the MID-FAT SPINDLE would give you a wide q-factor. Use the 104×4 SPIDER with the chainring mounted on the inside position.
Q-Factor = 183mm
Use the FAT spindle with a 104×4 Mountain spider if you’ve got a fat bike, . Mounting the chainring on the inner portion provides a chainline for 177mm rear ends and mounting on the outside provides a chainline for197mm rear ends
Q-Factor = 201mm
