What is the SRAM DUB English Bottom Bracket MTB SuperBoost+ for?

The SRAM DUB English Bottom Bracket MTB SuperBoost+ is designed for mountain bike frames that use SuperBoost+ rear spacing (157mm) with an English/BSA threaded shell (73mm). The DUB system's oversized spindle standard delivers excellent crankarm compatibility and durability, with the SuperBoost+ version positioning the chainring further outboard to match the wider 157mm SuperBoost+ rear axle spacing and 56mm chainline standard.

SuperBoost+ is used on a select range of mountain bikes designed for maximum tire clearance and traction. If your frame uses 157mm rear spacing with BSA threading, this is the correct DUB bottom bracket. Compatible with SRAM DUB SuperBoost+ cranksets. Confirm your frame's rear axle spacing and shell width before ordering.
