From cyclocross to loading up the miles on bumpy backroads, Easton's EC90 SL Discs are the go-fast wheels you've been waiting for. Tipping the scales at a feathery 1,610 grams for a wheelset, the EC90s are smooth-riding, unbelievably aero, and fast, fast, fast! Easton's Fantom rim shape has been scaled down to 38mm deep, providing major aero advantages in a mid-depth wheel. The Road Tubeless rims let you ride with lower tire pressures and fend off flats. With fierce acceleration and the compatibility of a six-bolt rotor mount you'll be impressed by how your standard riding loops take on a whole new speed with new apexes and lines, up and down.
