The Tracer Pro 2Bliss Ready features an all around cyclocross tread for mostly hard-packed courses. The tread remains stable at low tire pressures, while the Tracer rolls smooth on tarmac and finds grip when taking tricky turns onto gravel or grass. The GRIPTON compound, meanwhile, stays supple in freezing temperatures and even delivers surprising grip over wet roots. All this makes the Tracer a tremendous gravel and adventure tire, as it rolls well on asphalt and hooks up on earth and gravel. And with this 2Bliss Ready version, you'll also benefit from its versatility, ability to run lower tire pressures, and added puncture protection. - Casing: 60 TPI - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON - Flat Protection 700x33mm: BlackBelt; 700x38mm: Endurant Casing and BlackBelt
