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.

FAQ

What is MTB SuperBoost+ and why does it need a specific bottom bracket?: SuperBoost+ is a 157mm rear axle spacing standard used by some MTB frames to allow wider tire clearance and improved chainline geometry. It requires a specific bottom bracket that positions the crankset outboard for the correct 56mm chainline.

Can I use this bottom bracket in a standard 73mm MTB frame?: No. A SuperBoost+ bottom bracket provides a 56mm chainline suited for SuperBoost+ frames. Installing it in a standard 73mm frame will shift the crankset too far outboard and compromise chainline geometry.

How do I confirm compatibility before ordering?: Confirm your frame uses English/BSA threading with a 73mm shell width and that your crankset is a SRAM DUB model rated for SuperBoost+ chainline before ordering.

Best For

Mountain bikers on SuperBoost+ frames (157mm rear axle spacing) running SRAM DUB SuperBoost+ cranksets who need the correct bottom bracket for the wider chainline.
