BB92 bottom bracket shells:

The BB92 bottom bracket shells have a width of 89 to 92 mm and a press-fit depth of 41 mm. These bottom brackets are compatible with standard MTB cranksets, including Boost spacing. These bottom brackets are press-fit.

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 cranksets can also be fitted to frames with wider bottom bracket shells. There are also Wide Road and Wide MTB cranksets. These axles are also longer than standard axles, although the Road Wide axle, at 112 mm, corresponds to the standard MTB axle.

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