Easton EC90 TT Carbon Wheel Set

Easton EC90 TT Carbon Wheel Set. Easton EC90 TT Carbon Wheel Set: Stiff and extremely aerodynamic carbon wheelset, built for high performance time trial and triathlon use. New for 2008 is the EC90 TT carbon. Based on the EC90 Aero, but with a new aerodynamic R4 TT front hub that creates 50% less frontal exposure. The Easton carbon 56mm deep cross-section rims offer incredible rotational and lateral stiffness providing quicker acceleration and a smoother ride while cutting through the air. This hand-built wheel set essential equipment for time trials and triathlons.Easton wheels are meticulously tuned by skilled craftsmen to achieve uniform spoke tension. This simple procedure vastly strengthens the wheel and greatly reduces spoke failure. Further, it allows us to sufficiently tension the spokes so that the wheel has the compound attributes of light weight, stiffness, and durability. The spokes are only one aspect of the wheel that sets us apart. Every aspect of the wheel, from bearings to nipples, has been refined and improved. Wheel building is as much art as it is science. High, uniform spoke tension is necessary to build strong wheels that stay true. Nothing does this better than experienced human hands. It's a painstaking process. Easton's systematic approach to precision tensioning and truing sets the standard in the industry. Hubs: F-R4TT, R-R4 with narrower front 51mm flange spacing to reduce frontal area and wind drag. Wider, larger pawl carrier improves torque handling Axles: Large diameter 12mm axles made from 7050 alloy with precision ground bearing journals. Airfoil end caps reduce drag Bearings: Precision sealed cartridge bearings and tool-free pre-load adjustment Cassette Body: 7050 alloy Rim Depth: 56mm Width: 21mm Nipples: Alloy Black (internal) Spokes: Sapim™ bladed black 16F: radial 20R: radial NDS / 2-cross DS Size: 700C – Tubular 1370g pair
