The Token Ninja BB86/92 DUB Bottom Bracket is engineered to eliminate annoying creaks and reduce premature bearing wear in press-fit frame shells. By utilising a thread-together centre section, the drive and non-drive cups thread directly into each other inside your frame. This design locks the entire interface together, ensuring precise bearing alignment, increasing lateral drivetrain stiffness, and eliminating the movement that causes unwanted frame noise.
Built using Token's proprietary Fusion technology, the alloy bearing cups are encased in a durable fibre-composite shell. This hybrid structure seamlessly conforms to minor frame tolerances without causing harsh metal-on-metal wear. Coupled with patented X-Seal technology, the sealed bearings remain protected against water, mud, and trail grit, maintaining smooth performance over extended service intervals.
Choose between Premium High-Carbon Steel bearings for exceptional everyday durability or TBT Ceramic bearings for maximum racing efficiency. The TBT option pairs titanium-coated races with high-precision ceramic balls to significantly reduce friction, providing a fast, silky-smooth spin for competitive road, gravel, and mountain bike setups.
Interlocking Thread-Together System: Non-drive and drive side cups thread together inside the frame shell to eliminate creaking and prevent bearing misalignment.
Fusion Composite Construction: Blends an alloy structure with a fibre-composite outer layer to protect frame bores and deliver superior stiffness.
Premium or TBT Ceramic Options: Available with durable high-carbon steel bearings or titanium-coated TBT ceramic bearings for ultra-low rolling resistance.
Frame Shell Compatibility: BB86, BB89.5, BB92 (41mm inner diameter, 86.5mm–92mm shell width)
Crankset Spindle Compatibility: SRAM DUB (28.99mm axle)
Bearing Options: Premium High-Carbon Steel OR TBT Ceramic
Unit Weight: 92g (excluding spacers)
✅ Noisy Press-Fit Frames: Permanently solves frame creaking by joining both cups together with an internal threaded lock.
✅ SRAM DUB Users: Purpose-built to run 28.99mm SRAM DUB crank spindles smoothly inside standard 41mm press-fit frame shells.
✅ All-Weather Reliability: Features dual-lip X-Seals that effectively keep out mud, dust, and water during wet Australian rides.
❌ Threaded BSA Frames: Designed specifically for 41mm press-fit frame shells; it will not fit traditional threaded bottom bracket shells.
❌ Non-DUB Cranks: Incompatible with 24mm Shimano or 30mm crank axles without using model-specific bottom bracket variants.
❌ Basic Tool Availability: Requires specialized 16-notch 44mm bottom bracket installation tools to properly thread and torque the cups together.
Installing a DUB spindle into a 41mm shell leaves narrow tolerances, so proper alignment during installation is critical. Use two 16-notch 44mm bottom bracket wrench tools (or a tool paired with a torque wrench) to hold the non-drive side fixed while torquing the drive side. Be sure to apply a thin layer of waterproof grease to the inner composite threads and frame contact points before installation to ensure a quiet, friction-free fit.
