Designed for cyclists who want
the top-level climbing performance of the Elan with added rim toughness. The
Aspin is durable, light and aerodynamic at the same time.
wheel size: 700c
weight: 1480g set [610g/870g]
spoke count: aero 20F/24R
hubset: Aspin wheel systems orbit around a
proprietary hubset designed and manufactured in the USA.
Patented Differential Flange Diameter™ on the rear hub lends a mechanical
advantage effectively doubling the number of functional pulling spokes;
increasing wheel durability. 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. Hubs also feature
precision cartridge bearings with low drag supplementary contact seals and
bearing preload adjustment on both front and rear hub shells.
freehub mechanism: Black anodized, CNC machined
steel freehub body has 3 sprung steel pawls for a bomb-proof torque transfer
system. Pawls are driven by 3 hardened steel leaf springs. The system is strong,
simple and dependable.
rims: This 435 gram rim is slightly shorter than
the Elan Aero rim at 22mm tall. The rim section has a slightly thicker wall for
added impact strength and toughness. The brake sidewalls are brushed for
optimized weight savings.
spoke & nipple: Black, aero profile 14/15 gauge
spokes with patented 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.
extras: Rolf Prima Aspin wheel systems include
custom reinforced rim tape and steel quick release skewers (105g / set).
