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.
Key Features:
- SUPRA LV Fluid. A low-viscosity lubricant for ceramic pulley bearings, with high flow characteristics for a fast, smooth-running environment.
- 18T Oversize Pulley. The 18T tension pulley design results in smoother chain movement. Compared with original 11T derailleur pulleys it reduces chain deflection angles.
- Asymmetric Design. 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. The hollow pulley frame allows a much larger bearing, giving superior rotation and stable support for the 18T pulley while keeping contamination out.
