The PDX is named for the Portland airport code-home to some of the toughest 'cross races in America. The lugs are built to provide enough grip in wet and muddy conditions, but spaced widely enough not to pack up with soil and minimize rolling resistance.
- Tubeless tubular design provides outstanding performance in all conditions
- Proven tread design ideal for muddy conditions or any loosely packed terrain
- 3.0mm knob height balances rolling efficiency and traction demands; center ridge rolls smoothly on hard surfaces
- Widely spaced tread lugs shed mud quickly
