Donnelly tires were formerly branded as Clement Tires, but a name change was required. The tires are exactly the same, and once all Clement labelled tires are sold through, the same models will be listed only under the Donnelly brand.

So, your cyclocross season generally mud, mud, and more mud. Sure, there is sand, some pavement and rocky, rooty jumble on the course as well, but powering through the mud is crucial to any chance of a strong finish, let alone a finish at all. The Donnelly PDX design has been hailed by tubular riding cross racers for their success in the muck of the Pacific Northwest once the rain begins to fall, and has bee applied all over the country is such conditions. But perhaps tubular use isn't your game? You have been struggling to get the standard clincher to deliver, but you need lower pressures, a wider true contact patch, and no chance of pinch flats. Buck up, because Donnelly developed a tubeless ready technology that brings you the Crusade PDX Tubeless Cyclocross Tire.

You get the same narrow, tall and wide open tread spacing with a near constant center pattern which has proven itself in the mudholes of cyclocross lore with a tubeless ready design that brings a reinforced, yet supple sidewall that can handle the lower pressures without fear of destruction, and best of all- no pinch flats. Donnelly rates the PDX Tubeless for a 35-60 psi range, and while we doubt anyone will push the upper range, we know many will fully explore lower numbers. Just so you know what the rated range is, we'll repeat, 35-60. The tread rubber itself is a Shore 70A durometer, which is firm enough to reduce rolling resistance, but soft enough to flex and give, as a lower pressure system needs to. The knobs carve into the surface and pull through, delivering the traction and power you need but without retaining the thick, mud that packs in and reduces capability. When the tire penetrates and rips through the PDX does, you will fully appreciate the results. Just keep in mind that narrower knobs are less stiff and a great mud tire rarely reacts well on hardpack, especially in corners. The design can and will hold in loose ice and snow, with grass traction decent until it fully packs down.... Read More
