 Zipp Track Hubs take every feature to the next level of strength, stiffness, and bombproof durability. With a 60mm spoke hole circle diameter and a 15mm oversized solid 17-4 stainless steel axle, a Zipp track hub is both laterally and torsionally stiffer than one constructed with a traditional 47mm diameter hole circle and 1018 steel axle.

Without removing any material from the hub flange, our Spoke Hole Impact Forming Technology improves the grain structure and hardens the alloy around the spoke hole. Using SHIFT and the same exclusive Z310.9 alloy as the 88 and 188 road hubs, our track hub flanges are practically impervious to cracking around the spoke holes with any spoke tension or lacing pattern.

These bombproof hub shells ride on ultra-precise Swiss bearings with non-contact shields to eliminate all seal drag. Track hubs are supplied with Zipp's top quality track nuts, which replace the standard serrated interior surfaces with floating washers made of hardened stainless steel.
