This tire combines a fast-rolling diamond center with aggressive shoulder knobs that only hook-up when the terrain gets soft, muddy, or a bit sketchy. The Tubeless Tubular version, with 260TPI SuperPoly casing, offers a unique combination of tubeless and tubular construction that's more secure on the rim and more comfortable at lower air pressures, is fast-rolling, and is compatible with both tubeless sealants and tubeless tire plugs. This tire includes PPS2, a combination of our sub-tread Puncture Protection System and an additional layer inside the casing to increase resistance to punctures. The Presta valve includes a removable core. \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eHandmade\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Handmade tires combine many attributes to create the most comfortable and low rolling resistance tires.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eTubeless Tubular\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Tubeless Tubular system maintains all the performance benefits of the best handmade tubulars.
