IRC Boken 36mm gravel tyre review

With a file tread and high air volume, the new IRC Boken tyre works well on dusty bridleways

The newly released IRC Boken is a classic gravel bike tyre, with a file tread across its centre coupled to a row of more widely spaced knobs at its edges. Unwrapping the tyre, the first thing you notice is how tacky the rubber feels. IRC emphasises its ultra-gummy compound, designed for added traction.
