"Lightweight, Durable, Affordable... pick two." This is something of a rule when it comes to wheelsets, and it holds especially true with carbon clincher wheels. However, manufacturers Carbon-Ti and Schmolke have staged a coup of sorts with the introduction of some impressive hubs and rims. For us at Fair Wheel, offering X-Hub SP hubs and SL 45 rims as a complete wheelset wasn't even a question. This is absolutely the most exciting wheelset we've ever built - it's light, aerodynamic, durable, and can be offered at a price literally hundreds of dollars less than any other premium carbon wheelset. At 1270 grams, these offer the convenience and accessibility of a 700c clincher wheelset at the weight of a high-maintenance tubular wheelset.
Schmolke SL 45 Carbon Clincher Rims
While most weight-conscious riders would balk at a 45mm deep aerodynamic wheels, Schmolke's SL 45 rims achieve a rare feat - they are lighter than almost any other carbon clincher rim, even those that are substantially shallower in depth. Yet, these rims share many of the features of other modern carbon road rims: internal spoke nipples, a wider tire bed, and an intelligently designed aerodynamic cross section. Each rim includes rim washers that reduce friction at the nipple/rim interface while spreading load from spoke tension to increase longevity of the built wheel.
Understanding the shortcomings of carbon fiber wheels on rim brake bicycles, Schmolke has paid extra attention to friction-related heat resistance. Using state-of-the-art resin in their molding process, Schmolke can claim an impressive glass transition point of 230ºC (446ºF). For riding steep, winding descents - and for heavier riders especially, this feature adds an invaluable safety component.
SL 45 rims feature an elegant semi-gloss finish over a carbon weave, with Team Edition white and red printed logos.
Schmolke rims are manufactured in Germany, and are covered under a 2 year warranty with a Crash Replacement option. Schmolke SL rims carry a rider weight limit of 105kg (230 lbs).
Carbon-Ti X-Hub SP Hubs
Italian manufacturer Carbon-Ti has built a reputation for well-designed, expertly manufactured products. Their X-Hub SP series hubs are attractive, lightweight, and durable. The 7075-T6 aluminum hub shells house high quality steel cartridge bearings with a user-friendly bearing preload design. The freehub mechanism is equipped with four pawls and 28 engagement points, and is available in configurations to fit either Sram/Shimano 11-speed or Campagnolo cassettes. With a combined weight of 220 grams, this hubset is lighter than many other manufacturers rear hubs alone.
Sapim CX-Ray SP Spokes
The CX-Ray has long been our go-to spoke for custom wheel builds. These spokes have a excellent reputation for longevity, and they are the lightest spokes available that don't make extreme compromises on affordability or fatigue life. As a straight-pull spoke, the CX-Ray SP is less prone to the premature fatigue failures often seen in classic J-bend style spokes. In this wheelset, we've fitted these black CX-Ray spokes with Pillar's aluminum internal nipples and Schmolke's rim washers.
