Zipp hubs are meticulously designed to deliver exceptional performance, reliability, and durability. The internal components of these hubs play a crucial role in ensuring smooth operation and efficient power transfer.
Key Internal Components of Zipp Hubs:
-
Axles: Zipp hubs feature robust axles that provide a solid foundation for the wheel, ensuring stability and strength during intense rides. The axles are designed to accommodate various axle standards, including quick-release and thru-axle systems, enhancing compatibility with different bike setups.
-
Bearings: High-quality cartridge bearings are utilized within Zipp hubs to minimize friction and ensure smooth rotation. These bearings are sealed to protect against contaminants, extending their lifespan and maintaining consistent performance. Zipp's Cognition hubs, for example, incorporate advanced bearing preload systems that automatically adjust to maintain optimal bearing load, enhancing durability and reducing maintenance requirements.
-
Freehub Mechanism: The freehub body houses the engagement mechanism that allows for coasting and efficient power transfer when pedaling. Zipp's Cognition hubs feature the Axial Clutch technology, which disengages the ratchet mechanism when coasting to reduce drag and increase efficiency. The updated Axial Clutch V2 system utilizes a Sylomer spring mechanism, providing 54 points of engagement for quick responsiveness and improved durability.
-
Pawls and Ratchet Rings: In hubs like the ZR1, Zipp employs a six-pawl design arranged in two groups of three, providing 66 points of engagement. This configuration ensures rapid engagement for a responsive ride, with the pawls engaging with a 33-tooth ratchet ring to transmit power efficiently.
-
Seals and End Caps: Durable seals and precisely engineered end caps protect the internal components from dirt, moisture, and debris, ensuring longevity and consistent performance. The improved seal designs in hubs like the ZR1 enhance durability by preventing contamination of the bearings and internal mechanisms.
