Find the road less travelled on the new EA70 AX. Joining forces with the EA70 and EC70 AX Bar in our AX adventure road line, the new EA70 AX wheel has the durability to withstand trail riding but is translated to drop bar applications with center lock hubs and 11-speed road compatibility. From bikepacking adventures loaded with gear, to washboarded gravel descents with only your wheels and tires providing the compliance, we have you covered. The welded tubeless ready rim boasts a generous 24mm internal rim width that increased tire volume and gives an optimal tire profile for 35 to 50C tires. It’s the perfect wheel to round out any adventure drop bar build.

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.
