Combined with the fast-rolling centre-line for speed, these features allow for a more aggressive, versatile and dependable ride on multiple rugged terrains, in differing conditions.\u003cbr\u003e\u003cbr\u003eThe GRAVINE is launched in Challenges Handmade Tubeless Ready (H-TLR) construction. This construction has raised the bar of tubeless-ready tyres, bringing amazing comfort, handling and ride quality. Handmade Technology combined with innovative rubber compounds also minimises rolling resistance (Crr) for the best performance and overall experience. Available in two versions, GRAVINE and GRAVINE XP both available in sizes 40 and 45mm. Adding this new gravel model ensures that performance and dependability are met, no matter the riding conditions.\u003cbr\u003e\u003cbr\u003eSMARTplus COMPOUNDThe GRAVINE comes with the gravel-specific tread compound, made of a special higher durometer, and natural SMARTplus rubber. While providing reduced wear and enhanced durability, the SMARTplus rubber compound still retains its natural properties and offers improved shock absorption, better grip and control, and reduced rolling resistance.\u003cbr\u003e\u003cbr\u003eGANZO PPS - Puncture Protection SystemThe GRAVINE and GRAVINE XP feature the GANZO PPS puncture protection system. A tight weave, multi-component, puncture protection, narrow, special fabric placed between the rubber tread and the casing.\u003cbr\u003e\u003cbr\u003eCORAZZA ARMOUR GOLDExclusive feature of the XP tyre range is the Corazza Armour Gold, which increases the tyres puncture protection and robustness further, by including an additional Bead-to-Bead layer of tightly woven material. The additional layer reinforces the entire tyre and makes the GRAVINE XP a great tyre for more endurance riding or simply a more dependable tyre on more rugged terrain, in multiple and adverse conditions.","brand":"Challenge","offers":[{"title":"700x45 \/ Black","offer_id":58364894445949,"sku":"CH-00593","price":80.0,"currency_code":"GBP","in_stock":true},{"title":"700x40 \/ Black","offer_id":58364894478717,"sku":"CH-00591","price":80.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/8747\/2765\/files\/Challenge---GRAVINE-XP-H-TLR-Black-260tpi-700x45_1200x1200_999412b8-8f51-4a7a-bcab-b7fdf20fa635.jpg?v=1783503868"},{"product_id":"challenge-strada-pro-h-cl-black-300tpi-700x25-1","title":"Challenge - STRADA-PRO-H-CL-Black-300tpi-700x25","description":"The Strada is Challenges go-to champion for efficiency and sublime road feel.
