Sram DUB crank axles 28.99 mm:

SRAM has developed its own axle standard for DUB cranksets. SRAM DUB cranksets have an axle diameter of 28.99 mm and are only compatible with bottom brackets designed for DUB cranksets. The MTB DUB cranks have a longer axle, 112 mm, than the road bike DUB cranks, which are 106 mm. This means the MTB cranks can also be fitted to frames with wider bottom bracket shells. There are also Wide Road and Wide MTB cranks. These axles are also longer than standard axles, although the Road Wide axle corresponds to the standard MTB axle.

Standard MTB cranks and Boost MTB cranks have the same axle lengths. The Superboost and Wide MTB cranks have longer axles and each require different bottom brackets or additional spacers.
