G30 Cranks

Description |

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. This combo lives in that wide open world occupied by bikes that are neither road nor mountain and can be the perfect solution when more crankarm-to-chainstay clearance is needed, while keeping the road chainline of the R30 crank. Check out the table below and compare the specs of all four crank combinations to help decide which model would best suit your needs.

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