FAQ

What does a self-extracting bolt do and what do M18 and M30 refer to?: Self-extracting bolts thread into the crankarm and simultaneously extract the arm from the spindle during removal, eliminating the need for a separate crank puller tool. The M18 and M30 sizes correspond to different DUB crankset generations.

Is this kit compatible with all SRAM DUB cranksets?: This kit is compatible with all SRAM DUB cranksets. The M18 and M30 sizes cover different DUB crankset generations. Check your existing bolt size to confirm which you need.

When should crank arm bolts be replaced?: Replace both bolts as a set when damage or stripping is found rather than replacing just one. Self-extracting bolts can strip if overtorqued or if the crankarm is forced onto the spindle without proper technique.
