The Token Ninja 24mm Shimano Bottom Bracket solves the annoying creaks and premature bearing wear common to press-fit frames. By utilizing a thread-together center section, the drive and non-drive sides lock directly into one another inside your bottom bracket shell. This guarantees perfect bearing alignment, dramatically increases lateral drivetrain stiffness, and eliminates the lateral movement that causes frame noise.
Built around Token's innovative Fusion technology, the alloy housing is wrapped in a fibre-composite compound that interfaces smoothly with your frame. This design absorbs subtle frame tolerances while preventing harsh metal-on-metal contact. Fitted with patented X-Seal seals, this bottom bracket guards against water and road grime for smooth, long-term performance.
Choose between Premium High-Carbon Steel Bearings for rugged everyday durability or Token's TBT Ceramic Bearings. TBT Ceramic models pair titanium-coated races with ceramic balls to reduce rolling resistance and maximize power transfer for race-day performance.
Thread-Together Fusion Housing: Combines precision alloy bearing cups with a composite shell that threads together internally to eliminate creaks and misalignment.
Dual Bearing Options: Available with high-carbon Premium Steel bearings for daily durability or TBT Ceramic bearings for minimal rolling resistance.
Patented X-Seal Protection: Advanced dual-lip sealing technology shields internal bearings from water, mud, and road grit while maintaining low friction.
Spindle Diameter: 24mm (Shimano Hollowtech II compatible)
Shell Fit Options: BB86, BB89.5, BB92, PF30, BB30, or BB386 (depending on model variant)
Bearing Type: Premium High-Carbon Steel OR TBT Ceramic (Titanium-Coated Ceramic)
✅ Noisy Press-Fit Frames: The threaded interlocking system locks both cups together inside the shell to permanently eliminate creaks and movement.
✅ Shimano Crank Owners: Designed specifically to fit standard 24mm crank spindles like Shimano Hollowtech II without needing sloppy adapters.
✅ All-Weather Riders: The X-Seal system offers exceptional defense against wet weather and grit, keeping the unit spinning smoothly for longer.
❌ Standard Threaded Frames: Designed primarily for press-fit frame shells; users with BSA threaded frames should use standard threaded bottom brackets.
❌ Non-24mm Cranks: Not directly compatible with 30mm or SRAM DUB (28.99mm) spindles unless using model-specific conversion kits.
❌ Basic Installation Tools: Requires a specialized 16-notch 44mm bottom bracket installation tool rather than standard press-fit drift tools.
When installing a Ninja bottom bracket, make sure to use two proper 16-notch 44mm BB tools (or one BB tool and a 3/8" torque wrench) so you can hold the non-drive side stationary while torquing the drive side to spec. Always apply a light layer of grease to the outer composite shell before threading it together—this ensures a silky installation and adds an extra layer of defense against creaking.
