The TOKEN BB3724 Ninja Thread‑Together Bottom Bracket for Shimano is a high‑performance solution designed specifically for TREK BB90 and BB95 frames running Shimano 24 mm cranksets. Built to eliminate creaking, extend bearing life, and improve drivetrain stiffness, this bottom bracket is a proven upgrade supplied by Brisbane bike shops and installed by professional bicycle service and drivetrain specialists across Queensland.

Press‑fit bottom brackets commonly develop noise and premature wear due to frame tolerances and repeated use. The TOKEN Ninja BB3724 addresses these issues with a precision‑engineered thread‑together design that stabilises the interface between frame, bearings, and crankset.

Eliminating Creaking in Press‑Fit Frames

TREK BB90 and BB95 bottom bracket systems rely on extremely tight tolerances that can loosen over time, resulting in creaks under pedalling load. The BB3724 Ninja uses a thread‑together bottom bracket system that mechanically joins both sides inside the frame, preventing independent movement and eliminating noise at the source.

This makes it a common recommendation during bottom bracket replacement and drivetrain noise diagnosis at Brisbane bicycle service centres.

Fusion Construction for Precision Fit and Durability

TOKEN’s proprietary Fusion Construction combines an alloy bearing shell with an outer layer of engineered plastic and fibre reinforcement. The alloy shell provides a rigid, accurately supported platform for the bearings, while the composite outer layer allows precise machining and a secure, vibration‑free fit inside the frame.

This fusion of materials improves durability, reduces flex, and protects bearings from premature wear, even under high torque and long‑distance riding.

Thread‑Together Locking System for Increased Stiffness

The BB3724 Ninja extends the alloy shell so the left and right sides lock together inside the frame, effectively tying the frame, crankset, and bottom bracket into a single structural unit.

This design delivers measurable gains in drivetrain stiffness, improved power transfer, and smoother pedalling efficiency — benefits valued by performance‑focused road cyclists throughout Brisbane and South East Queensland.

Bearing Options to Suit Different Riding Priorities

The BB3724 Ninja is available with Premium high‑carbon steel bearings for durability and everyday reliability, or TBT ceramic bearings for reduced rolling resistance and maximum performance. Both options are suitable for Queensland conditions and regular training or racing.

Purpose‑Built for TREK BB90 and BB95 Frames
