When there is mud on the course the Donnelly PDX is the tubular of choice. It’s race-proven PDX tread and innovative tubeless casing create the ultimate tubular tire. PDX is the airport code for Portland, Oregon, where frequent rains create some of the muddiest cyclocross courses you’ll find anywhere. Although the PDX excels in the mud, this tire is truly an all-conditions performer. The center knobs are aligned to give you a fast roll on hard pack and pavement, no matter what the weather conditions. Aggressive side knobs offer superior cornering, and the leading edge of the knob gives you extra traction for acceleration out of the corner. Whether it’s mud, loose dirt, wet grass, snow or sand, the PDX can handle it all.
