This is the medium-depth aerodynamic road wheel that you’ve been waiting for. The Easton EC90 SL tubular rear wheel takes the proven Easton Fantom rim shape and scales it down to a shallower 38-millimeter depth. The round "Fantom" noses keep them stable in cross winds. Furthermore this wheel offers fierce acceleration, smooth, dependable braking and impressive aerodynamics. From the spring classics to rough and tumble cyclocross racing, you’ll be hard pressed to find a condition where the EC90 SL is out of its element. EC90 SL wheel is entirely built by hand from start to finish and acoustically tuned. It combines top-end materials, a methodical build and the award winning Echo hub.
Every aspect of the new Easton Echo hubs were designed to improve bearing life, increase stiffness and cut weight. Easton hits the reset button and rethought every component: from the bearing architecture to the machining methods, spoke engagements, the angular contact bearings, the sealing methods, grease —the resulting hubs offers market-leading durability and power transfer. Because of an increased number of cogs the bearing distance has been more and more reduced, which takes a negative effect on the bearings lifespan. Instead of this the new Echo rear hub features an extra wide bearing distance of 95mm - 50mm more than its predecessor. Furthermore Easton has reversed the drive mechanism. The pawls now are placed inside the hub body and a drive ring on the free hub. That means an earlier engagement, so the power will be transferred faster to the wheel.
Advice: Carbon rims can only be used with special carbon brake pads.
