ZIPP COGNITION RIM Front 61803 Ceramic Bearing (x2) #11.2018.067.001

The ZIPP Cognition Rim Front ceramic bearing kit allows you to upgrade the front hub of Cognition rim brake wheels with 61803 ceramic hybrid bearings. This upgrade reduces friction and starting torque compared to the original steel bearings, for a measurable reduction in rolling resistance.

Manufactured in Germany to ZIPP specifications, with ceramic balls and corrosion-resistant stainless steel rings, these bearings stand out for their durability and smoothness. To upgrade a complete wheelset, pair this kit with an equivalent kit for the rear hub as well as a kit for the freehub body.
