What Our Gearhead® Experts Are Saying: "I’ve used this bottom bracket on a couple of long-travel trail and enduro bikes with 83mm shells. The wider DUB setup keeps the chainline clean for Boost cranksets, and the sealed bearings hold up great in wet conditions. Super easy install and nearly maintenance-free."The SRAM DUB English Wide Bottom Bracket connects crankarms and keeps power transfer smooth—ride after ride. Designed specifically for 83mm BSA threaded frames, this version offers a perfect fit for SRAM DUB mountain cranksets with Boost 55mm chainlines, creating a more stable and efficient drivetrain interface. Sealed cartridge bearings and SRAM’s Gutter Seal Technology™ help extend bearing life by keeping out mud, grit, and moisture—even in the wettest trail conditions. And with a single oversized DUB spindle that simplifies compatibility across bottom bracket standards, this is the go-to option for riders who prioritize reliable performance and future-proof crank integration.
