The newest addition to the Gravel King Family is also available with increased puncture resistance, thanks to Panaracers ProTite Plus technology.Extra Building on the success of the GravelKing Slick Plus and the GravelKing SK Plus, both industry leading tyres in the gravel category. Panaracer has developed the next generation of the gravel tires in the GravelKing Semi Slick Plus.Designed as a dryer condition or race day ready and fast rolling tyre, the Semi Slick is made for those riders who want to go fast while maintaining great control, traction and climbing prowess.The Semi Slick Plus features an all new tread pattern consisting of a smooth diamond pattern centre with more aggressive side lugs. This tread pattern allows the rider to keep speed going into corners and maintain control throughout any transition a gravel ride could present. The GravelKing SS incorporates a supple 120 TPI casing with a nylon puncture resistant belt and Panaracer’s proprietary ZSG (Zero Slip Grip) compound.FEATURESTubeless Compatible (Up to 60psi),ZSG Advance Compound,AX-Alpha Advanced Alpha Extra Cord,Anti-Flat Casing,Bead: Folding,Sizes: 700 x 32c / 700 x 35c / 700 x 38c / 700 x 43c / 27.5 x 1.9 (48c),Weight: 370g / 420g / 450g / 530g / 590g,Colours: Black/Black, Black/Brown,Made in Japan.TECHNOLOGIES:NEW ProTite Shield PlusUltra-strong reinforcing material is wrapped around the whole tyre with nylon taffeta lining the treads to provide added protection against side cuts as well as punctures from dented rims or piercings.ZSG Natural CompoundOur own very low rolling resistance as the premium compound. Its enhanced wear resistance makes it perfect for a long lasting training tire with an excellent ride.AX-Alpha - Advanced Alpha Extra CordAX technology uses extremely narrow cord which is weaved at a super high density into the casing for lightness and flexibility. This increased density improves resistance to cuts and abrasions.Anti-Flat CasingAnti-puncture reinforcement throughout the tire strengthens resistance to cuts and pinch flats.
Built on the same concept as our Gravelking and Gravelking SK models, the EXT version incorporates the same technology on top of a specially designed tread tailored to work best in muddy and sloppy conditions. Better puncture resistance while retaining the superb balance of a light riding feel and grip.

The Pirelli Cinturato Gravel RC is the gravel-racing specific tyre, derived from our experience in the biggest competitions around the World and the feedbacks of our PRO athletes. The tread design is inspired by the Scorpion XC RC, focussed on two key features: higher average speed on straight and fast lines, improved lateral grip when off-road cornering.Gravel racing specific tyre designed with feedback from Pro athletesSpeedGRIP Compound is a gravel-specific rubber formulation born from the Pirelli experience in the World Rally ChampionshipThe tread design is inspired by the Scorpion XC RCTechWALL Gravel features a cut-resistant 120tpi fabric all over the perimeter of the tyre still offering a supple riding feelingPLEASE NOTE: Despite one of the images showing this tyre to have a wire bead, this is not the case and it does have a folding bead.The SpeedGRIP Compound is a gravel-specific rubber formulation born from the Pirelli experience in the World Rally Championship where the performances of speed and grip on and off-road are crucial. This chemical formulation relies on the polymer matrix of the MTB-specific SmartGRIP Compound while lowering its rolling resistance. The gravel application requires good speed and on-off road capabilities, for this reason our engineers tweaked the compound features towards a better energetic efficiency with a little compromise on the grip, the result is a predictable compound with solid performances on and off road.Our engineers wisely combined the technologies derived from road-specific reinforced casings with the MTB-specific casings to obtain our most advanced gravel casing whose performances are obtained with the use of special fabric reinforcements and thicker layers of rubber in specific areas of the tyre. On the road the majority of punctures are caused by the penetration of sharp objects while off-road the most common punctures are caused by sidewall cuts, for this reason the TechWALL Gravel features a cut-resistant 120tpi fabric all over the perimeter of the tyre still offering a supple riding feeling.
Open Tubular (Clincher) An open tubular is constructed using the same casing and tread materials and process as a tubular, but instead of sewing the casing together (closed), the sides of the tubular casing are folded around aramid fibre cords to produce beads. This ‘open’ design performs like a tubular, yet conveniently mounts like a standard clincher tyre. If combined with a Latex inner tube the ride becomes even closer to that of a tubular, offering excellent traction and cornering, low rolling resistance and shock absorption.
Challenge Almanzo Gravel Open Tubular TyreThis highly-effective gravel tyre features a tubular construction and double-layered puncture protection for excellent durability. The 'open' design of the tyre performs like a tubular, yet conveniently mounts like a standard clincher tyre. Plus, its tight tread offers excellent grip at high speeds, making it a reliable racing tyre even on tougher surfaces. Designed to give you more control than the Strada Bianca tyre and faster rolling resistance than the Gravel Grinder when cornering.Features: Use: Hard Pack Dirt to Light Gravel Size: 700 Tyre Width: 33mm Internal Rim Width: 15-19mm TPI: 260 Bead: Aramid Casing: SuperPoly Flat Protection: Double PPS BAR: 3-9 PSI: 45-130 Weight: 385gTechnologies: Challenge Handmade Clinchers (HCL): Our Handmade Clinchers are made from the same materials and processes as our handmade tubulars but instead of sewing an inner tube inside the casing is wrapped around an aramid bead to form a tire that fits on a clincher rim. The HCL is moulded flat, not in a horseshoe like a TLR or VCL. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance. A tubeless tire is moulded in a U-shape to make the sidewalls rigid, so the system does not “burp” or lose air when it deforms after it encounters a surface imperfection. The tubeless tire's stiff sidewall compromises its ability to equal a supple HCL with a latex inner tube.Buy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
