The Details
Materials
- Utilizing Ferei’s FCT patented technology (magnetic coupling system), it offers convenience in maintenance and versatile options for customization (allowing the replacement of couplers with different gear ratios).
- The FCT technology preserves the advantages of the first-generation toothed engagement mechanism while introducing a completely new design that significantly improves the performance metrics we care about in hub systems.
- The new-generation hub structure is simpler and lighter, maintaining excellent durability and rigidity.
- Additionally, disassembly and maintenance are made simpler.
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)
