WHEELS Mfg T47A Bottom Bracket

T47a refers to the asymmetrical version of the T47 threaded standard. This specific bottom bracket is designed for frames with a 77.5-79mm shell width, ensuring the correct offset and alignment for your drivetrain.

Yes, this unit is specifically engineered for cranks with 29mm spindles, such as those from SRAM DUB. It provides a precise fit that minimizes play and maximizes power transfer.

The sleeve serves two purposes: it acts as a barrier against dirt and grime entering the bearings, and it prevents internal cables or hydraulic hoses from rubbing against the rotating crank spindle.

Yes, the Enduro ABEC-3 bearings are designed to be easily serviced or replaced. This allows you to maintain smooth operation over the long term rather than replacing the entire bottom bracket assembly.

Yes, you will need a tool compatible with a 48.5mm, 16-notch pattern. Most standard external bottom bracket tools for this specific diameter will work.

Unlike press-fit systems that rely on friction, the machined aluminum cups thread directly into your frame. This creates a secure, stable interface that is significantly less prone to the creaking often associated with press-fit bottom brackets.
