hubset: The 58 Track wheel orbits around a Track specific hub design and is manufactured in the USA. Optimized flange contours provide full spoke elbow support, increasing spoke life. Hubs also feature precision cartridge bearings with low drag supplementary contact seals.

rims: The proprietary 58mm tall, deep-section carbon fiber rim is light and offers superior lateral and torsional stiffness. Brake sidewalls are reinforced with fiberglass for improved braking performance and durability. The combination of low spoke count, minimal rotational weight and exceptional aerodynamic performance makes the 58 Track wheel system one of the fastest tubular wheel sets available in its category.

spoke & nipple: Black custom bladed, 14 gauge spokes and internal alloy nipples with nylon inserts contribute to clean aerodynamic performance and superior, long-term durability. Patented, Jacketed Nipple Design™ and Dish Reducing design™ reduce spoke bending loads and rear wheel dish to increase spoke fatigue life.
extras: Rolf Prima 58 Track wheel systems include alloy valve extenders.
