White Industries

M30 Black Mountain Crank Arms (Extractor Colors)

When choosing a drivetrain system there aren't more important characteristics than consistency and durability, providing smooth power mile after mile. And like all of their componentry, White Industries'' M30 Mountain Crank Arms are built to last long after competing parts have failed. The MR30 crank is an evolution on the long-standing square taper drivetrain, providing more consistent contact throughout a pedal stroke. And using a 30mm aluminum spindle allows the crank to be light yet durable. 

You can pair the M30 Mountain Crank with a 1x, 1x Boost, or 2x chainring setup for the exact experience you are gearing up for. Compatible with BSA, T47, and Press Fit 30 bottom bracket systems. Crank arms available in both black and silver, with your choice of extractor bolt color. Upgrading your drivetrain system with White Industries'' MR30 Crankset will increase the efficiency and longevity of your bike while catching everyone''s eye.
