This model excels on both \u003cstrong\u003ewet and dry terrain\u003c\/strong\u003e, handling soft, rocky, root-filled, and grass-covered ground with efficiency. The clincher construction is compatible with inner tubes and hook-bead rims, providing a reliable solution for both amateur and competitive cyclocross riders. The Grifo’s versatility makes it the ideal choice for cyclists looking for a single tyre that can adapt to the weather and course variability typical of cross racing.\u003c\/p\u003e\n\n\u003ch3\u003eSuperior Traction and Grip Technology\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eGrifo Wire\u003c\/strong\u003e combines \u003cstrong\u003elow-resistance knobs\u003c\/strong\u003e with an optimized center section to maximize traction during both pedaling and braking. This innovative design allows the tyre to maintain consistent grip even when ground conditions change rapidly. The tread geometry promotes water dispersion and reduces sink-in on muddy terrain, essential features for modern \u003cstrong\u003ecyclocross\u003c\/strong\u003e. The firmer center section ensures predictable response during accelerations and through demanding corners, giving the rider the confidence needed to perform at their best.\u003c\/p\u003e\n\n\u003ch3\u003eConstruction Details and Performance\u003c\/h3\u003e\n\n\u003cp\u003eThe 700x33 model weighs 460 grams, a competitive figure that does not add excessive weight to the bike. The \u003cstrong\u003enylon casing\u003c\/strong\u003e ensures tear resistance and long-lasting durability, a key element on terrain with natural obstacles. The recommended inflation pressure range is 2.1 - 2.7 bar, allowing adjustments based on personal preferences and current course conditions. Lower pressures improve grip and comfort, while higher pressures reduce rolling resistance. The \u003cstrong\u003eclincher\u003c\/strong\u003e construction makes installation and maintenance easier, making it accessible even to less experienced cycling enthusiasts.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eTyre type: \u003cstrong\u003eCyclocross\u003c\/strong\u003e clincher with inner tube.\u003c\/li\u003e\n\u003cli\u003eSize: 700x33 mm.\u003c\/li\u003e\n\u003cli\u003eWeight: 460 grams.\u003c\/li\u003e\n\u003cli\u003eCasing: Tear-resistant \u003cstrong\u003enylon\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eInflation pressure: 2.1 - 2.7 bar.\u003c\/li\u003e\n\u003cli\u003eKnobs: \u003cstrong\u003eLow-resistance\u003c\/strong\u003e for mixed terrain.\u003c\/li\u003e\n\u003cli\u003eCompatibility: Hook-bead rims with \u003cstrong\u003einner tubes\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eTubeless ready: No.\u003c\/li\u003e\n\u003cli\u003eUse: \u003cstrong\u003eWet, dry, soft, and rocky terrain\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eColor: Black.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Challenge","offers":[{"title":"33mm \/ Black","offer_id":54666148675930,"sku":"01900","price":26.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/GRIFO_Race_VCL_Black.webp?v=1788168354","url":"https:\/\/www.all4cycling.com\/en\/products\/copertone-challenge-grifo-wire-700x33-nero","provider":"All4cycling ","version":"1.0","type":"link"}
