The big news from Donnelly is the upcoming EMP gravel tire, which pulls its name from the airport code for Emporia, Kansas, home of a kinda popular gravel race that crushes souls every year. The tire is a departure from their usual tread design, getting a tighter tread block pattern without a well-defined center strip like most all of their other tires. It’s still designed to roll fast, which is key if you’re racing any long distance gravel bike event, but with bigger side knobs to handle more aggressive cornering.
- Smooth-rolling center knobs and aggressive shoulder lugs
- Soft rubber compound for extra grip and shock absorption
- Integrated puncture protection belt under the tread
- Tire Intended Use: Gravel
- Labeled Size: 700 x 38
- Tire Bead: Folding
- Tire Diameter: 700c
- Tire Type: Tubeless Ready Clincher
- Weight: 484
- Weight (oz): 17
- Flat Protection: Tread
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 beads. UST rims should be paired with UST-specific tires for best results.
