What is the SRAM DUB English Bottom Bracket for?

The SRAM DUB English Bottom Bracket is designed for frames with a standard English/BSA threaded shell (68mm road or 73mm MTB width). The DUB system uses a single oversized spindle standard that works across every SRAM bottom bracket shell specification, delivering better crankarm compatibility, superior element protection, and longer-lasting performance than previous spindle designs. The threaded BSA design installs cleanly into English-threaded shells with standard bottom bracket tools, with left-hand threads on the drive side.

This is the go-to DUB bottom bracket for the most common frame shell standard in cycling. Compatible with all SRAM DUB cranksets across road, gravel, and mountain applications. Confirm your exact frame shell width (68mm or 73mm) and crankset DUB compatibility before ordering.
