BOS is the airport code for Boston, Massachusetts, a hotbed of North American cyclocross and home to some of the harshest weather and the toughest race 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 mud slinger is even more aggressive than our race-proven PDX cyclocross tire. It features stiff, buttressed side-knobs for outstanding traction in super muddy corners and slick off-cambers. The unique center tread pattern is all bite when it comes down to a long muddy tractor pull.
