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. 

The G30 uses White Industries M30 mountain crank arms mounted to their 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.

Note: Spindle, crank bolts, extractors, adjusting collar, and chainring lockring included.  Chainrings and bottom bracket sold separately.
