What is the SRAM DUB English Bottom Bracket 100mm MTB for?

The SRAM DUB English Bottom Bracket 100mm is designed for mountain bike frames with a 100mm English/BSA threaded shell, most commonly found on fat bikes and specific purpose-built frames requiring extra-wide bottom bracket spacing. The DUB system's oversized spindle standard delivers the crankarm compatibility and durability that these demanding applications require.

The 100mm shell is a specialized specification. Confirm your frame uses this shell width before ordering. Compatible with SRAM DUB cranksets designed for 100mm shell applications. Not interchangeable with standard 68mm, 73mm, or 83mm shells.
