The Challenge Grifo Open TLR 700x33c tire (reference 00605 / tan sidewall) is the benchmark choice for cyclocross across mixed, dry, and muddy conditions. Built using Challenge's renowned "Handmade" construction process (HTLR), this open tubular tire features a high-density 300 TPI SuperPoly casing that delivers the supple ride quality and low rolling resistance of a tubular. It conforms effortlessly to uneven terrain, providing maximum traction and cornering confidence. The legendary Grifo tread design delivers exceptional lateral grip through off-camber sections while shedding light mud effectively. Fully Tubeless Ready, it allows riders to run lower tire pressures for enhanced grip and pinch-flat protection.
