Zipp's Tangente Course R30 Clincher Tire is just the ticket for those of us looking for a beefy tire that can handle everything from jarring cobbles to pristine pavement at speed. Boasting low rolling resistance, sure grip, and an extra wide profile, this tire provides confidence in varied weather conditions and rolls smoothly over the roughest roads. Billed as a race worthy training tire for days when the road isn't pristine, the Course R30 utilizes its relatively high, 120 TPI nylon casing and beefy 30mm width to soak up the bumps. The wider stance allows for lower tire pressure and an increased contact patch, which pairs with the fast rolling casing for confident grip in corners and an overall smoother ride than narrower tires. To cap things off, Zipp incorporates a tread pattern designed to shed water and maintain grip even in rainy conditions for sure cornering through the storm.
