Fast rolling, surprisingly capable, and unmistakably Ultradynamico, the Mars blends speed and traction into a tire that's equally at home on spirited trail rides, bikepacking trips, and everyday rides where the route isn't always the point.\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"431\" data-end=\"908\"\u003eAt the heart of the Mars is a \u003cstrong data-start=\"461\" data-end=\"495\"\u003econtinuous ramped center tread\u003c\/strong\u003e that keeps rolling resistance low while still providing dependable braking traction when things get steep. Large, well-supported side knobs inspire confidence when cornering on loose gravel, dry dirt, and hardpack, while the generous spacing between knobs clears mud before it has a chance to slow you down. Whether you're carving corners or climbing out of them, the Mars is designed to keep you moving forward.\u003c\/p\u003e\n\u003cp data-start=\"910\" data-end=\"1433\"\u003eThe \u003cstrong data-start=\"914\" data-end=\"936\"\u003eJFF (Just For Fun)\u003c\/strong\u003e casing strikes an ideal balance between ride quality, weight, and durability. It features tread rubber that extends slightly down the sidewalls for added protection against everyday trail hazards without compromising the supple ride that makes Ultradynamico tires so enjoyable. Riders tackling extremely rocky terrain or who frequently puncture tires may want one of Ultradynamico's heavier-duty casings, but for most riders the JFF delivers an outstanding combination of comfort and performance.\u003c\/p\u003e\n\u003cp data-start=\"1435\" data-end=\"1655\"\u003eFrom weekend bikepacking trips and all-day gravel adventures to local singletrack and daily rides, the Mars JFF is a versatile tire that encourages you to take the interesting route—even if it leads somewhere unexpected.\u003c\/p\u003e\n\u003ch3 data-section-id=\"19zqy0x\" data-start=\"1657\" data-end=\"1669\"\u003eFeatures\u003c\/h3\u003e\n\u003cul data-start=\"1670\" data-end=\"2095\"\u003e\n\u003cli data-section-id=\"1vo4h07\" data-start=\"1670\" data-end=\"1715\"\u003eFast-rolling continuous ramped center tread\u003c\/li\u003e\n\u003cli data-section-id=\"1da6dfb\" data-start=\"1716\" data-end=\"1772\"\u003eConfident braking traction on loose and mixed surfaces\u003c\/li\u003e\n\u003cli data-section-id=\"1b8o14z\" data-start=\"1773\" data-end=\"1827\"\u003eAggressive side knobs for predictable cornering grip\u003c\/li\u003e\n\u003cli data-section-id=\"1dsmgz8\" data-start=\"1828\" data-end=\"1874\"\u003eWide tread spacing helps shed mud and debris\u003c\/li\u003e\n\u003cli data-section-id=\"1kk2f43\" data-start=\"1875\" data-end=\"1936\"\u003eSupple JFF (Just For Fun) casing for an excellent ride feel\u003c\/li\u003e\n\u003cli data-section-id=\"1anycqg\" data-start=\"1937\" data-end=\"2006\"\u003eExtended tread onto the sidewall for additional puncture protection\u003c\/li\u003e\n\u003cli data-section-id=\"bxxt7l\" data-start=\"2007\" data-end=\"2028\"\u003eTubeless compatible\u003c\/li\u003e\n\u003cli data-section-id=\"1ahh00d\" data-start=\"2029\" data-end=\"2075\"\u003eFSC-certified recyclable cardboard packaging\u003c\/li\u003e\n\u003cli data-section-id=\"15zgjr4\" data-start=\"2076\" data-end=\"2095\"\u003eSold individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-section-id=\"1yl5694\" data-start=\"2097\" data-end=\"2115\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul data-start=\"2116\" data-end=\"2350\"\u003e\n\u003cli data-section-id=\"rnnblp\" data-start=\"2116\" data-end=\"2203\"\u003e\n\u003cstrong data-start=\"2118\" data-end=\"2138\"\u003eAvailable Sizes:\u003c\/strong\u003e\n\u003cul data-start=\"2141\" data-end=\"2203\"\u003e\n\u003cli data-section-id=\"3n8ydy\" data-start=\"2141\" data-end=\"2159\"\u003e29 x 2.2\" – 665g\u003c\/li\u003e\n\u003cli data-section-id=\"h0hkzr\" data-start=\"2162\" data-end=\"2182\"\u003e27.5 x 2.2\" – 625g\u003c\/li\u003e\n\u003cli data-section-id=\"1h23ggu\" data-start=\"2185\" data-end=\"2203\"\u003e26 x 2.2\" – 570g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"fe25i1\" data-start=\"2204\" data-end=\"2229\"\u003e\n\u003cstrong data-start=\"2206\" data-end=\"2225\"\u003eTubeless Ready:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli data-section-id=\"lrhily\" data-start=\"2230\" data-end=\"2262\"\u003e\n\u003cstrong data-start=\"2232\" data-end=\"2243\"\u003eCasing:\u003c\/strong\u003e JFF (Just For Fun)\u003c\/li\u003e\n\u003cli data-section-id=\"1ekxsch\" data-start=\"2263\" data-end=\"2350\"\u003e\n\u003cstrong data-start=\"2265\" data-end=\"2285\"\u003eRecommended Use:\u003c\/strong\u003e Trail, gravel, bikepacking, ATB riding, mixed-surface adventures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"2352\" data-end=\"2589\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eIf you're looking for a tire that's quick on the pedals, predictable in the corners, and packed with personality, the \u003cstrong data-start=\"2470\" data-end=\"2496\"\u003eUltradynamico Mars JFF\u003c\/strong\u003e is ready for wherever your next ride takes you—even if that's somewhere a little off course.\u003c\/p\u003e","brand":"Ultradynamico","offers":[{"title":"27.5 x 2.2 inches \/ Black","offer_id":52293278793959,"sku":null,"price":75.0,"currency_code":"USD","in_stock":false},{"title":"27.5 x 2.2 inches \/ Tan","offer_id":52293278826727,"sku":null,"price":75.0,"currency_code":"USD","in_stock":false},{"title":"26 x 2.2 inches \/ Black","offer_id":52293278859495,"sku":null,"price":75.0,"currency_code":"USD","in_stock":false},{"title":"26 x 2.2 inches \/ Tan","offer_id":52293278892263,"sku":null,"price":75.0,"currency_code":"USD","in_stock":false},{"title":"29 x 2.2 inches \/ Black","offer_id":52293278925031,"sku":null,"price":75.0,"currency_code":"USD","in_stock":false},{"title":"29 x 2.2 inches \/ Tan","offer_id":52293278957799,"sku":null,"price":75.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/1969\/2472\/files\/ultradynamico-tires-ultradynamico-mars-jff-tire-1248477982.webp?v=1783694788","url":"https:\/\/ottawabikeandtrail.com\/products\/ultradynamico-mars-jff-tire","provider":"Ottawa Bike and Trail, LLC","version":"1.0","type":"link"}
