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.
