Donnelly Sports EMP 650B

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: 650B x 47
- Tire Bead: Folding
- Tire Diameter: 650B
- Tire Type: Tubeless Ready Clincher
- Weight (oz): 19.6
