Michelin Jet XC2 Racing Line 29" Tire Where Rubber Meets the Dirt When the course is fast, dry, and demanding, a semi-slick tread is the right call. The Jet XC2 Racing Line is built for hardpack XC riding, shaped around a tight, low-profile tread pattern that keeps rolling resistance low without giving up cornering bite on firm ground. The Cross Shield^2 carcass uses a 2x150 TPI construction with four additional 150 TPI strips at the bead for pinch protection where the rim delivers the most impact. Gum-X compound threads the needle between traction and rolling efficiency - you get the grip you need to hold a line through corners without fighting the tire on the straights. This is the tire for XC racers and fast trail riders who know that on the right terrain, your wheels should be moving you forward, not slowing you down. Semi-slick tread patternclosely spaced, low-profile blocks minimize rolling resistance on hardpack and firm XC terrain so you carry more speed with less effort Gum-X compoundbalances grip, rolling efficiency, and durability in a single compound, so you do not have to trade cornering traction for straight-line speed Cross shield^2 carcass, 2x150 TPI construction with four additional 150 TPI strips at the bead resists pinch flats and sidewall damage while keeping the casing supple and lightweight Tubeless readyon a compatible rim to reduce weight, lower optimal pressure, and add a layer of flat protection via sealant SPECIFICATIONSOverall Diameter (in)29 inch Display Size60-622 (29x2. 35 Hooked, Hookless)MSPN98133Position Both Tube Type A4 47/61mm 622mm Tire Weight (lbs)760g Bead Foldable Bead | Michelin | Jet Xc2 Racing Line 29" Tire 29X2. 35, Gum-X, 2X150 Tpi, E25 | Rubber
