For riders who need the lightest wheel sets the Easton EC90 wheels provide a carbon tubular alternative to their top clincher range. These wheel sets are available in deeper rim depths than the aluminium equivalent.
First there is the Easton EA90 SLX which is an extremely lightweight climbing wheel at 1175g for a set, at a rim depth of 25mm, which also has sufficient strength to withstand sprinting. This wheel has been used by top teams with an excellent reliability record.
Next comes the EA90 SL, which is a more versatile wheel at a rim depth of 38mm and a weight of 1232g, giving it the ability to fulfil climbing needs while also having the aerodynamic properties to perform well on flatter rights. Easton say that this is a do-everything wheel and they have also equipped it with ceramic bearings.
The next three wheels are all more specialist. There is the Aero tubular EC90 at a room depth of 56mm, which is made for road racing along the flat or for time trials. These provide rapid acceleration with lateral stiffness.
The Easton EC90 TKO wheel also has a rim of 56 mm, but is a track specific wheel with a unique design in which the wheel mounts to the hub using aluminium
cogs and a splined design with a lock ring. These wheels are carefully designed to withstand the immense loads of track racing.
Finally Easton produce the EC90 TT tubular wheel at a rim depth of 90mm, which fulfils the needs of time trial and triathlon riders who need the ultimate in aerodynamic cutting force to achieve maximum consistent speed.
