BOS is the airport code for Boston, Massachusetts, the original hotbed of North American ‘cross and home to some of the harshest weather and the toughest courses. If you’re pinning on a number in New England you better be ready for rain, roots, ruts and mud. And, you better have a set of Donnelly BOS tubulars in your quiver. This tire is even more aggressive than our mud-proven PDX. It features buttressed side-knobs for outstanding traction in super muddy corners and off-cambers, and a center tread pattern that is all bite when it comes down to a tractor pull.

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 45
- Tire Bead: Folding
- Tire Diameter: 700c
