Boken Doublecross

Brand: IRC

Boken Doublecross is the dual-sport gravel and cyclocross tyre of IRC, sitting between a race CX casing and an all-terrain gravel tyre. The 38 and 42 mm versions share a nearly continuous centre tread with widely spaced shoulder knobs around 2.1 mm tall, while the older 33 mm version used a different pattern. The casing is 60 TPI with reinforced sidewalls and an aramid tubeless-ready bead, and the rubber is the house Boken compound, which IRC calls its grippiest.
