AOPW Pulley Systems

Asymmetric Oversized Pulley Wheels for Shimano, SRAM and their electronic groupsets. The patented asymmetric frame grows the tension pulley to 18T while still fitting the original derailleur arm, cutting chain deflection without a new mech.

Pulleys & cages

The 18T tension pulley design results in smoother chain movement. Compared with original 11T derailleur pulleys it reduces chain deflection angles.

Asymmetric Design

Asymmetric Design

Pulleys & cages

TRiPEAK's patented asymmetric pulley frame lets the tension pulley grow to 18 teeth while still fitting the original derailleur arm — maximum efficiency from minimal change.

Hollow Frame

Hollow Frame

Pulleys & cages

The hollow pulley frame allows a much larger bearing, giving superior rotation and stable support for the 18T pulley while keeping contamination out.
