SRAM DUB BB30 Road Wide

The SRAM DUB BB30 Road Wide Bottom Bracket is engineered to integrate SRAM’s DUB crank sets with road and gravel frames featuring a BB30 bottom bracket shell.

This bottom bracket is specifically designed to accommodate SRAM’s Wide crank sets, providing additional clearance for wider tyres, which is particularly beneficial in gravel and off-road applications.

Compatibility

Designed for frames with a 68mm and 73mm wide, 42mm inner diameter BB30 bottom bracket shell.

It pairs seamlessly with SRAM’s DUB Wide crank sets, which add 2.5mm of clearance on each side, facilitating the use of wider tyres for gravel and off-road riding.

Standard DUB crank sets may not be compatible due to the additional clearance provided by the Wide version.

Spindle Interface

Utilises SRAM’s DUB technology, featuring a 28.99mm spindle diameter that standardises crank and bottom bracket compatibility across various standards.

Bearings

Equipped with sealed cartridge bearings, available in both stainless steel and ceramic versions, ensuring smooth operation and durability.

Construction

Features an aluminium body that balances strength and weight, contributing to the overall durability and performance of the bottom bracket.
