Donnelly BOS Tubeless SC 700c CX Tyre

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 in your quiver.

This tyre 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 centre tread pattern that is all bite when it comes down to a tractor pull.
