SRAM DUB crank axles 28.99 mm:

SRAM has developed its own axle standard for DUB cranks. SRAM DUB cranks have an axle diameter of 28.99 mm and are only compatible with bottom brackets designed for DUB cranks. MTB DUB cranks have a longer axle (112 mm) than road bike DUB cranks (106 mm). This means that 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, at 112 mm, corresponds to the standard MTB axle.

Standard MTB cranks and Boost MTB cranks have the same axle length, 112 mm. The MTB Wide cranks have a 118 mm axle and the Super Boost+ cranks a 121 mm axle, and each requires different bottom brackets or additional spacers.
