Designed for speed on smoother trails and drier conditions, the Rail excels
in both and is fast on the tarmac too. Close spacing of the center tread makes
for swift progress, while aggressive shoulder tread gives you the confidence
to let rip on the loose stuff. The rail is available for mountain bikes and gravel

Everything about the Rail was designed for speed. From the specialty center
and transition knobs for lower rolling resistance to the tapered cornering
knobs for agile maneuverability, this tire offers a fast ride.
