These are the medium-depth aerodynamic road wheels you’ve been waiting for. The EC90 SL takes the proven Fantom rim shape and scales it down to a shallower 38-millimeter depth. These wheels offer 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. The EC90 SL is available in tubular or certified Road Tubeless carbon clincher. EC90 SL wheels are entirely built by hand from start to finish and acoustically tuned. These wheels combine top-end materials, a methodical build and the award-winning Echo hubset.

Tubeless Rim/Tire Cross-Section

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.

Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.

UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire bead. UST rims should be paired with UST-specific tires for best results.
