The updated version of our most popular 650B tire is 1.5 mm wider and tubeless-compatible. The new Babyshoe Pass measures a true 42 mm wide on most rims. Mounted tubeless, it’s even more at home on its namesake pass high in the Cascade mountains.

Babyshoe Pass (1330 m/4350 ft) runs between the great volcanoes of Mount St. Helens and Mount Adams in the Cascade Range. This long climb on a gravel road provides a “back-door” way from Seattle to Portland, which avoids the crowded Puget Lowland. As you climb out of the dense evergreen forests, the mountain vistas open up and you see glimpses of Mount Adams.

For this challenging ride, you will appreciate the Babyshoe Pass TC, which rolls as fast as a racing tire on the paved lower sections of the climb, yet floats across the gravel on the higher parts.

The Babyshoe Pass TC is tubeless-compatible in both standard and extralight casings. When used with tubes, we recommend Schwalbe SV12 or SV14A tubes.
