Challenge Grifo Tubeless Vulcanised CX TyreThe Challenge Grifo is an exceptional all-around use tyre that's designed to provide fantastic grip when the terrain is loose, but to also roll fast when speed is a must. Featuring a central ramped tread profile to ensure that you get the best acceleration, plus aggressive side knobs, superb grip is activated when leaning into corners and when tackling technical trail sections. This tyre is engineered to be robust, reliable and dependable - the Grifo is a very worthy addition to your racing/training arsenal. Classed as one of the best all-around cyclocross tyres every created by Challenge, this tyre excels in wet, dry, soft packed, rocky and root-infested course conditionsFeatures: Tubeless Ready: Yes Use: Cross Training: All Around Soft Pack Size: 700 Tyre Width: 33mm Internal Rim Width: 15-19mm TPI: 120 Bead: Aramid Casing: Nylon BAR: 3.1-5.1 PSI: 40-75 Weight: 300gTechnologies: Vulcanized Tubeless Ready (VTR): The highest level of performance offered by car, truck and motorcycle tyre manufacturers is a vulcanized tubeless system. While this is an old technology for cars and trucks, for bicycles it is relatively new and did not even have an internationally accepted design standard (ISO or ETRTO) until recent years. By eliminating the inner tube it is possible to lower the weight and create a softer, more comfortable, more efficient, lower rolling resistance tyre system by running lower tyre pressure. Challenge started introducing Vulcanized Tubeless Ready (VTR) tyres in recent years because the ISO and ETRTO standards for proper VTR tire and rim fit have finally been completed. These standards ensure your safety and your ability to fit and service the tyres with hand tools. Buy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
Challenge Paris Roubaix Open Road TyreA max. volume 27mm sect. tubular for fast but safe riding on worst condition roads. Delivers the best comfort you can achieve from a top performing racing tyre. Perfect for all riding conditions, this tyre gives you fast-rolling resistance and excellent handling when cornering.Features: Size: 700 Tyre Width: 27mm Internal Rim Width: 13-19mm TPI: 300 Bead: Aramid Casing: Superpoly Flat Protection: Double PPS BAR: 6-9 PSI: 90-130 Weight: 285gTechnologies: Challenge Handmade Clinchers (HCL): These 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.
Challenge Almanzo Gravel Open Tubular TyreThis highly-effective gravel tyre features a tubular construction and double-layered puncture protection for excellent durability.

Continental Terra Trail ShieldWall Foldable TR TyreFeaturing a high-quality PureGrip compound, this gravel bike tyre delivers excellent grip, elasticity and smooth-rolling performance even on demanding mixed terrain conditions. Continental also kitted out this model with its prestigious ShieldWall System for high-level puncture protection without any unnecessary weight. Another highlight is this model's tubeless-ready technology, which allows you to benefit from tubeless advantages such as the ability to run lower tyre pressures. This means you'll enjoy increased traction on rough terrain as well as lower rolling resistance and fewer chances of flats or punctures. Whether you're planning your next gravel adventure, CX racing event or simply taking the long road home, this versatile tyre is made to get you over the rough and smooth.Gravel Bike Tyre with PureGrip CompoundBased on activated silica compounds, this technology was originally intended as a performance level compound, but after intensive development at Continental's German R&D facility, an advanced new compound with outstanding grip, elasticity and rolling properties was developed. This new mix was given the self-explanatory name "Pure Grip", ranked just behind the brand's BlackChili compound and will be used in its updated performance products both in road and MTB sectors.Whilst providing great grip, it is also long-lasting and highly durable, which are both regarded as ongoing characteristics of Continental tyres.ShieldWall System Puncture ProtectionThe ShieldWall system combines the optimal combination of high puncture protection and the best smooth running properties with low weight. This is made possible by an additional, all-round puncture protection layer consisting of a finely woven cross fabric. This gives the tyre a high resistance to punctures and injuries. Despite the additional layer, the tyre has very good damping properties and has high flexibility to adapt perfectly to the ground. The revolutionary tubeless-ready base also allows for easy and uncomplicated mounting of the tyre.Tubeless ReadyThis tyre's carcass construction is robust and impervious against damage and penetration from off-road objects. The result is a versatile, low weight and attractive design. In addition, the Continental Terra Trail ShieldWall Foldable TR Tyre tyres can be used as tubeless or with an inner tube.Features: Compound: PureGrip Puncture Protection: ShieldWall System Use: Gravel, Cyclocross (CX) Electric Bike Compatibility: Suitable for E-bikes up to 25 km/h TPI: 180 TPI/EPI Bead Type: Folding Tubeless Ready: Yes Single or Pair: Single Weight: 450g (28" x 1.35 option)Manufacturer's Part Numbers: 1505050000 Black/Cream 28" 1.35 1505070000 Black/Black 28" 1.5 1505030000 Black/Black 28" 1.35 1505090000 Black/Black 27.5" 1.75 1505080000 Black/Cream 27.5" 1.75Buy Continental Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
