Our most iconic 650B tire has a perfect balance of on-pavement grip and off-pavement volume. Babyshoe Pass is remote pass nestled between the great volcanoes of Mount St. Helens and Mount Adams. It provides a back-door way from Seattle to Portland, avoiding the crowded Puget Lowland.

These tires roll as fast as racing tires on the paved lower sections of the climb, yet float over the gravel on the higher parts. They are surefooted on the descent to Trout Lake, where you can enjoy the famous huckleberry shakes at the local food spot.

The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse. The Extralight casing takes the performance, comfort and feel of your bike to an entirely new level. The Endurance casing is reinforced for extra sidewall protection and puncture resistance, while retaining the speed and comfort for which Rene Herse tires are famous.

The Babyshoe Pass is tubeless-compatible. For tubeless setup, we recommend SealSmart sealant. When used with tubes, we recommend the SV12 or SV14A tubes.

Made in Japan.
