With the Donnelly BOS in your arsenal, you'll be ready for the worst wet and mud conditions in cyclocross racing. It is purpose-built for mud, rain, roots, and ruts with  an open tread pattern. The ability to swap treads on race day is a key benefit of tubeless cyclocross tires. These are easy to setup on modern tubeless rims.

Big, aggressive knobs for muddy and wet cyclocross

Compared with the Donnelly PDX, the BOS is even more aggressive. The Donnelly BOS features big, reinforced side knobs for cornering traction and grip on off-camber sections. It's like a Challenge Limus in terms of intended use.

Tubeless-ready design for use on modern tubeless rims

The Donnelly BOS is designed for use with tire sealant on modern tubeless rims. Run that combo and you'll have a setup that's very resistant to punctures while providing grip and traction on wet and muddy terrain.
