The Token T47 Threaded External Bottom Bracket is designed for serious cyclists and mechanics building or maintaining bikes with T47 frame shells who require a reliable, high-performance interface for SRAM DUB cranksets. Its primary advantage lies in the combination of premium, smooth-spinning bearings and proprietary X-Seal technology that prevents contamination without adding excessive drag; however, users should note that it requires a specific 16-notch tool compatible with 48.5mm diameter cups for proper installation.

No, this specific model is engineered exclusively for SRAM DUB cranksets with a 28.99mm spindle.
Yes, the Token T47 outboard design is compatible with both 68mm and 73mm bottom bracket shell widths.
You need a 16-notch bottom bracket tool with an outside diameter of 48.5mm.
Threaded T47 brackets provide a secure, threaded interface that is generally less prone to creaking compared to traditional press-fit systems.
While the X-Seal is highly effective, it is recommended to inspect the bearings for smoothness every 3,000–5,000 miles or sooner if the bike is frequently exposed to mud and rain.
Ensure the bottom bracket cups are tightened to the correct torque and that frame threads were greased during installation.
Check for debris near the seal or signs of bearing wear; if contaminated, clean the area around the seal and re-apply light lubrication.
Verify that your crankset is a SRAM DUB model with a 28.99mm spindle, as this bracket is not compatible with standard 24mm or 30mm spindles.
To install this bottom bracket, ensure your frame shell is clean and properly chased for T47 threads. Apply a high-quality, waterproof grease to the frame threads before installing the bearing cups. You will need a 16-notch tool with a 48.5mm diameter fit to tighten the cups to the manufacturer's recommended torque specifications. For care, avoid using high-pressure water sprayers directly at the bearing interface, as this can force contaminants past the X-Seal. Periodically check that the cups remain tight to the frame, and perform a spin test during your routine drivetrain cleaning to ensure the bearings remain free of grit.
