White Industries G30 Gravel Cranks

White Industries G30 Gravel Cranks
The G30 is part of our 30mm spindle line of cranks which also includes the M30, A30 and R30 models. The G stands for gravel and the 30 is for the 30mm spindle. Made here in our shop, the G30 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, Its a White Industries road bike crank with a slightly wider Q factor.
The G30 uses our M30 mountain crank arms mounted to our R30 road spindle so you get road/gravel chainlines but with a bit wider Q factor as well as more room between your crank arms and chainstays. It is a direct replacement for most road and gravel 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 six crank arm lengths. Like we said, options!
