Kogel Bearings Aero Kolossos Oversized Cage Description:

The Kogel Bearings Aero Kolossos Oversized Cage is comprised of high-quality alloy pulley wheels complete with ceramic ball bearings that work to reduce chain drag, as well as a CNC-machined aluminum outer shield that fosters a streamlined aerodynamic profile.
