Named after the pass that carried the Olympian Hiawatha express train to Seattle, the Snoqualmie Pass tires are ideally suited for riding on the loose gravel of the rail trail that now traverses the pass. Enjoy the speed of the supple casing on pavement, and the floatation of a wide tyre on gravel. The Snoqualmie Pass also is a great way to transform the on-road performance of your 29? mountain bike. The Snoqualmie Pass is tubeless-compatible in both standard and extralight casing. When used with tubes, we recommend the SV17 or SV18 tubes.
