Jockey wheels for Shimano in ceramic or stainless steel. The pulley is injection-moulded around its bearing rather than pressed onto it — a zero-tolerance fit in a composite body that runs quieter and wears longer than aluminium.
Key Features:
- G5 Ceramic Balls. The ceramic bearings of the TRiPEAK C-Series use G5-grade ceramic balls paired with a precisely machined steel race, delivering excellent rotational performance.
- SUPRA LV Fluid. A low-viscosity lubricant for ceramic pulley bearings, with high flow characteristics for a fast, smooth-running environment.
- Composite Injection Molding. Unlike traditional press-fit bearing pulleys, TRiPEAK's injection-molded pulley fully encases its bearing for a zero-tolerance fit.
- Narrow-Wide Tooth. The narrow-wide tooth profile lets the pulley engage the chain more closely, significantly improving operational stability.
