Bearings

The axle core and side cover feature a threaded joint design, which rigorously tests the precision processing requirements. This not only provides convenience during the disassembly and reassembly of the wheelset, eliminating the need for readjusting disc brakes, but also addresses the drawbacks of traditional press-fit side covers. The wear of anti-loosening rubber rings in these covers can lead to hub misalignment and cover loss.

“For a road wheelset, 7.5º is on the quick side, and I appreciate this. There’s less lag when resuming pedaling from a coast, and it gives the wheels a higher-end feel…more polished.” – (44 Aerodynamicist)
