hubset: Apex wheel systems orbit around a proprietary hubset design. Patented Differential Flange Diameter™ on the rear hub lends a mechanical advantage effectively doubling the number of functional pulling spokes; increasing wheel durability. Silver, CNC machined, hub shells with oversized axles provide high strength, stiffness and light weight. Optimized flange contours provide full spoke elbow support, increasing spoke life. Precision cartridge bearings are easily serviceable.

freehub mechanism: CNC machined steel freehub body has 3 independently driven hardened steel pawls. The system is strong, simple and dependable.

rims: This rim is 22mm tall and has a uniform wall thickness for added impact strength and toughness. The brake sidewalls are brushed for optimized weight savings.

spoke & nipple: Silver, butted 14/15 gauge spokes with wrench flats and internal alloy nipples with nylon inserts contribute to clean aerodynamic performance and superior, long-term durability. Patented Self-Aligning Nipple™ technology and Dish Reducing design™ reduce spoke bending loads and rear wheel dish to increase spoke fatigue life.
