At 48 mm wide, the Hatcher Pass hits the sweet spot between narrow gravel tire (38 mm) and mountain bike volume (55 mm) – ideal for the latest generation of gravel and all-road bikes. Named after Lael Wilcox’ favorite road in Alaska, this tire perfect for Hatcher Pass: The front side of the climb is paved and leads to Independence Mine (an abandoned gold mine that is now a state park). The back side is dirt. In August and September there are fields of wild blueberries near the top.

The supple casing of Rene Herse all-road tires rolls smoothly over surface irregularities. The tread pattern interlocks with the road surface for superior cornering grip, wet or dry. The tread has enough thickness in the center to last thousands of miles, but it’s thin and supple on the shoulders where it doesn’t wear.

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.
