Description
The ZIPP COGNITION NSW Front Bearing (x2) is a genuine replacement kit for servicing the front hub of NSW wheels. It contains two 61803 bearings measuring 17 x 26 x 5 mm to restore your hub’s original smooth rotation.
These deep-groove ball bearings are sealed (2RS), have an ABEC 5 tolerance rating and contain stainless steel balls. They fit Cognition, 76 and 77 front hubs, and therefore ZIPP 202, 303, 404, 454, 808 and 858 NSW wheels.
Regular replacement keeps the hub turning smoothly and limits wear on the axle and hub shell. Using a suitable bearing press is recommended for careful installation.
