White Industries M30 Mountain Cranks

White Industries M30 Mountain Cranks

The M30 is part of our 30mm spindle line of cranks which also includes the A30, R30 and G30 models. The “M” stands for mountain and the “30” is for the 30mm spindle. Made here in our shop, the M30 draws on over 30 years of crank manufacturing experience with a focus on all the White Industries hallmarks; functionality, durability, and clean design.

The best way to describe this model is, “It’s a White Industries mountain bike crank”. Simple. The M30 is a direct replacement for most mountain cranks from the big “S” companies, but with a lot more options: two crank arm colors, eight extractor cap colors, three 1x chainlines, a 2x chainring option, and seven crank arm lengths. Like we said, options! Check out the comprehensive information below for all the details you’ll need to help navigate to the correct set up for your bike.
