Sram DUB crank axles 28.99 mm:

SRAM has developed its own axle standard for DUB cranks. The SRAM DUB cranks have an axle diameter of 28.99 mm and are only compatible with bottom brackets designed for DUB cranks. The MTB DUB cranks have a longer axle (112 mm) than the road bike DUB cranks (106 mm). This means that MTB cranks can also be fitted to frames with wider bottom bracket shells.
