Disc brakes have arrived in road cycling. Theyre proven in mountain and cyclocross, and with the new EC90 SL Disc wheels combined with the latest brake systems, there are no longer any compromises associated with going disc. The EC90 SL takes the proven Fantom rim shape and scales it down to a shallower 38-millimeter depth. The EC90 SL Disc is available in tubular or certified Road Tubeless carbon clincher and are entirely built by hand from start to finish and acoustically tuned. These wheels combine top-end materials, a methodical build and the proven M1 6-bolt disc hubset. Best of all, these wheels are future proof, they can convert to 15×100 & 12×100; parts sold separately.
