Easton EC90 Aero 56mm clincher makes a debut with slippery aerodynamics and excellent braking power. The carbon clincher matches the performance of the traditional aluminum clincher at a lesser weight and more stiffness. The rims are 22mm wide and 56mm deep. Easton has the ThermaTec treatment applied on the braking surface of the EC90 Aero. Maximum limit of heat the clincher can handle up to 500 degrees Fahrenheit.
Hand-laced and tuned to maintain an even spoke tension across each wheel, the spoke count for the 56mm clincher is 18 radial on the front and 20 radial non-drive side spokes, 2-cross drive side for the rear. Hubs are R4SL with ceramic type bearing. The EC90 Aero also features red alloy external nipples and Sapim CX Ray spokes.
A pair of Easton’s EC90 Aero 6mm clincher weighs 1658g and retails for $2000.
