Easton EC90 TT is the lightest 90mm-deep wheelset on the market. It is the result of years of engineering experience and repeated sessions at San Diego’s Low Speed Wind Tunnel. Weight shaving and durability/strength increase is done to the smallest details to become the lightest and durable aero wheelset. Technologies include Variable Nipple Bed which places material only where it’s needed to support spoke tension. The R4 TT hub reduces frontal exposure to the wind by as much as 50 percent. Hand built and acoustically tuned in Easton factory.
