The HEX Gravel Tire pairs a nano-particle-enhanced rubber compound, shared with ENVE's SES Race Day road tire, with a supple, lightweight casing built for speed. The hexagonal tread's three-way flex conforms to the terrain for consistent grip, while a sub-tread barrier and reinforced bead guard against flats without adding the weight of a full protective casing. What Our Gearhead(R) Experts Are Saying:"This tire disappears under me on fast gravel sections, rolling quicker than anything else I've run at this width. I still trust it in loose corners, which is the part I didn't expect from something built this light."
