Rolf Prima Aspin Clincher Wheelset 2011
Surprisingly light and hand built in Eugene, Oregon, the Aspin tips the scales in favor of lightweight and budget. Named for the famed climb in the French Pyrenees, the Aspin was designed as a climbing wheel with a low spoke count and low rim profile. Using the technology of the Elan, the Aspin combines a stiffer spoke set, bomb-proof hubs and beefier rims for overall added toughness. They are durable enough for everyday training and commuting, yet still light enough for race day. Model: Aspin Wheel size: 700c Category: Road Race, training, commuting, climbing Weight: 1595gm set [640gm/955gm] Spoke count: butted 20F/24R Rim: 22mm, alloy clincher Hubset: ST1.2 w/ alloy freehub body Hubset: Shimano, SRAM or Campagnolo Decal: Grey w/ red
Rims: The Aspin rim is designed for the rigors of everyday use. The 22mm tall, single cavity, alloy rim offers excellent lateral and torsional stiffness with additional toughness at a low weight. The brake sidewalls are CNC-machined for smooth, consistent braking performance. The Aspin is built for everyday training use but fast enough to use on race day.
Hubs: The Aspin wheelset is built around the ST1.2 proprietary hub. The rear hub features our Patented Differential Flange Diameter, which effectively doubles the number of pulling spokes and creates a more durable wheel. Black, CNC machined, hub shells with alloy front/steel rear axles with sealed cartridge bearings provide strength, stiffness and reliability. Upgrade to the Aspin SL and drop another 95 grams for a wheelset that accelerates even faster. Freehubs: The forged aluminum freehub body has 3 independently driven hardened steel pawls. The system is strong, simple and dependable. Spoke & Nipple: The Aspin wheel set features paired, 14/15 gauge custom butted spokes with wrench flats and internal alloy nipples to create a quicker accelerating, faster climbing wheel with superior, long-term durability. Self-locking thread technology ensures wheels stay true longer. Our patented, Self Aligning Nipple™ design significantly increases spoke fatigue life by allowing the nipple to orient to the spoke angle with less bend. Extras: Rolf Prima Aspin wheel systems include custom reinforced rim tape and steel quick release skewers.
