What is the SRAM DUB Crank Arm Bolt Kit M18/M30?

The SRAM DUB Crank Arm Bolt Kit contains the self-extracting bolts used to secure DUB cranksets to the spindle. It includes both M18 and M30 size bolts to cover the full range of DUB crankset configurations. These bolts are designed for tool-based installation and removal and are the correct hardware for all SRAM DUB cranksets. Replace if bolts are stripped, damaged, or lost during service.

Confirm your DUB crankset's bolt size requirement before ordering. Having a spare bolt kit on hand is a simple way to keep DUB cranks serviceable in the shop or on the road.
