Unlike commonly used press-fit bearing pulleys,

TRiPEAK adopts an injection-molded pulley design—

where the bearing is fully encased within the structure from the very beginning.

It is not simply pressed in.

The structure itself is engineered for the bearing.

1｜Zero-Tolerance Fit

Keeps the bearing in its optimal operating condition,

preventing looseness, misalignment, and unnecessary stress buildup.

2｜Composite Pulley Body

More wear-resistant and quieter than aluminum,

while improving overall drivetrain efficiency.

3｜Extended Service Life

Not only protects the bearing,

but also reduces chain wear,

maintaining performance over longer mileage.

The TRiPEAK Value — Even under long hours and high loads,it remains precise, quiet, and stable.
