The SRAM Innenlager DUB BB386 Road Wide bottom bracket is designed to provide a smooth, durable interface between your SRAM DUB crankset and a BB386 road frame. Built around SRAM’s proven DUB standard, it uses a 28.99 mm spindle diameter to optimize stiffness, reliability, and long-term performance while keeping the system simple and compatible. This bottom bracket is tailored specifically for wide road applications, giving extra clearance for modern frame designs, wider rear triangles, and larger tires often found on contemporary endurance and all-road bikes.
With high-quality sealed bearings and precise machining, the SRAM DUB BB386 Road Wide bottom bracket helps keep contaminants out and your drivetrain spinning freely in all weather conditions. It is an excellent choice whether you are building a new performance road bike or upgrading an existing frame to SRAM’s latest crank technology. Easy installation and straightforward maintenance make it a practical solution for riders who value efficiency, reliability, and a clean, integrated look in their bottom bracket area.
