The addition of Zipp’s 77/177 hubset raises Firecrest to whole new level: Best-in-class durability and improved bearing protection with no pre-load adjustment needed.
Like the rear Cognition hub found on our NSW wheels, the 177 rear hub features a star-flanged straight-pull hubshell design on the rear hub to distribute the load placed on the hub flange away from the bearings for accurate bearing bores and smooth rolling bearings regardless of spoke tension. We’ve also taken care to stack the opposing spokes on each arm of the hubshell to balance the load. This increases the fatigue life of each arm and allows us to use less material for a lighter hub. However, rather than stack the spokes directly on top of one another, we’ve offset them slightly so that the spokes do not intersect near the spoke head or adjoining shank, where the spoke is highly stressed, thereby preventing spoke breakage.
Optimized hub flange geometry and spoke hole attachment pattern with Sapim® CX-Sprint spokes (CX-Ray for 202 Tubular) to optimize torsional and lateral stiffness while improving durability.
New robust hub shape with distinctive graphics.
For those looking for a wider gear range, or tackling especially extreme terrain, a XD driver body for 177 is sold separately and easily installed to allow for more cassette options including our wide range 10-42t cassette. The hubset is designed to swap driver bodies without the need to re-dish the wheel.
