Formally know as the Clement MXP, Donnelly is the new brand name stamped onto the same tire that has been a cross staple over the last years. The MXP combines a unique tread pattern with our innovative tubeless ready design to provide an amazing all-conditions tubeless ready tire. It excels on grass, loose dirt, sand, moderate mud, hard pack and pavement. The MXP is named after the airport code for Milan, Italy, site of a World Cup cyclocross venue that calls for an all-conditions tire.The tread features a classic profile with several modern updates. Precise grooves in the central chevrons allow the tread to flex and more aggressive side knobs offer traction and control beyond what you might expect. If you could only have one cyclocross tire in your quiver, the MXP is the one to have.
