Rolf Prima Elan ES Clincher Road WheelsetRolf Prima's Elan ES Clincher Road Wheelset punches well above its literal and figurative weight. Packed with technology, these alloy clinchers are an excellent set of training and racing wheels Hand-built Elan ES Clincher: Light and Aero Alloy WheelsetThe Elan ES Clincher wheelset is light and fast, weighing in at a competitive 625 grams up front and 870 grams at the rear. This hand-built aero alloy wheelset is lighter than many of the other high-end racing wheels!The Elan ES wheelset features Rolf Prima's Paired Spoke Technology for an engineering edge alongside their Delta Rim Technology™, which chops through the wind for an aggressive aerodymanic performance when you want to distance yourself from the peloton Incorporating Rolf Prima's TdF3.0 hubset, which is light and comes with their bespoke Differential Flange Diameter™ for increased durability, the rear wheel is also SRAM and Shimano 11-speed compatible, so you have the freedom to run your preferred drivetrain. The steel bearings are strong, reliable, and smooth for a consistent rolling experience. A split of 20 Round Laser spokes at the front and 24 Round Race spokes at the rear delivers a balanced alloy wheelset with strength and reliability at its core.A strong and reliable alloy wheelset doesn't mean heavy and slow! You'll still enjoy an aerodynamic advantage as this Elan ES wheelset responds to bursts of acceleration and cuts through the wind with ease Features:Material: Alloy (Rim); Forged and Machined Aluminium (Freehub); Steel (Bearings)AerodynamicDurableLightweightResponsiveTubeless compatible rimIncludes rim strips and QR setWeight: 1.50kg (Total): 625g (Front); 870g (Rear)Technical Specification:Brake Type: CalliperFreehub: Shimano/SRAM 10/11-speedHubset: TdF3 0Spoke Count: 24Spoke Type: Round Laser/RaceRim Depth: 22mmRim Width: 22mm (maximum)Wheel Size: 700cKey TechnologyPaired Spoke Technology: Rolf Prima's Paired Spoke technology broke new ground when it was introduced in 1997. Bringing the spokes to the rim in pairs neutralises the left and right outward pulling forces, which allows them to build true wheels on lighter rims with fewer spokes. Fewer spokes and lighter rims help create increased aerodynamics and faster performing wheels Differential Flange Diameter™: Rolf Prima's patented oversize non-drive Differential Flange provides the leverage to transmit drive torque in the rear wheel to the non-drive spokes, thereby increasing the number of torque absorbing spokes Delta Rim Technology™: In skydiving, the Delta track is the fastest position for gaining forward airspeed. So, Rolf Prima mirrored this observation and adapted it for their Delta profile, which takes that cue using increased width and sidewall shaping to improve airflow and stability in straight on and crosswind situations. This wider rim is not just faster, but the additional tyre support improves cornering and handling in all riding conditions Buy Rolf Prima Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
