The ROLLCii RC20 bolt-on high flange track & fixed gear hubs are light but tough as nails, they're the secret sauce for anyone aiming to rule the streets.

• Lightweight Design: The hub shell and axle, meticulously machined both externally and internally, significantly reduce weight while maintaining a robust structure, showcasing a streamlined appearance.

• Extended Lifespan: Incorporating larger American Enduro 6902 sealed bearings for both front and rear hubs provides a smoother and more reliable riding experience, significantly prolonging the bearings' lifespan.

• Ease of Maintenance: The newly designed end caps facilitate easy adjustment of bearing preload and completely cover the bearings, helping to extend their lifespan.

• Optimized Power Transmission: Precision-machined washers and stainless steel screws (M6 for the front hub, M8 for the rear hub) perfectly align with the frame and fork dropouts, ensuring an efficient transfer of force into forward motion.

• Special Keyhole Spoke Holes: The uniquely designed spoke holes allow for a tighter integration between round and flat spokes and the hub, significantly increasing the wheelset's strength.

The ROLLCii RC20 hub seamlessly blends lightness, durability, and performance, catering to track bike enthusiasts who are reaching for the stars in their riding journey.
