Zipp: OVERVIEWZipp’s 76/176 hubset is dependable and durable, with a big speed capacity. The 76/176 features three pawls and 36 points of engagement. This hubset uses contact seals for outside the bearings, which is exposed to the elements, and non-contact seals for inside of the bearings to reduce drag. That combination provides a balance of speed and durability.FEATURESBetter bearing seals for increased durability3-pawl design, 36 points of engagementSame bearing size as premium-level Zipp hubsDisc-brake hub with Center-locking rotor interface.
