With no additional sidewall or tread puncture protection, it delivers a smooth, flexible feel that conforms exceptionally well to rough surfaces. That makes the JFF ideal for riders who prioritize speed, comfort, and road feel over maximum puncture resistance. Riders regularly tackling sharp rocks or particularly rough terrain may want to consider Ultradynamico's more reinforced casing options instead.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eFeatures:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eFast-rolling, near-continuous center tread\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eDelta-shaped knobs for confident braking on gravel and dirt\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eSupple JFF casing for excellent ride quality\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eDesigned for pavement, gravel, and mixed-surface riding\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eTubeless compatible\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003eAvailable in tan or black casing\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003e650b x 47.99 — 510g\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003e700c x 42 — 485g\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003e700c x 45 — 510g\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eIf you're building a \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003egravel, all-road, randonneuring, or adventure bike\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e and want a tire that feels fast on pavement without giving up capability when the pavement ends, the ROSÉ JFF delivers a great combination of speed, traction, and supple ride quality.\u003c\/span\u003e\u003c\/p\u003e","brand":"Ultradynamico","offers":[{"title":"Tan \/ 700 x 42mm","offer_id":52751924625639,"sku":null,"price":75.0,"currency_code":"USD","in_stock":false},{"title":"Tan \/ 650b x 47.99mm","offer_id":52751924691175,"sku":null,"price":75.0,"currency_code":"USD","in_stock":false},{"title":"Tan \/ 700 x 45mm","offer_id":52751924756711,"sku":null,"price":75.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 700 x 42mm","offer_id":52751924658407,"sku":null,"price":75.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 650b x 47.99mm","offer_id":52751924723943,"sku":null,"price":75.0,"currency_code":"USD","in_stock":false},{"title":"Black \/ 700 x 45mm","offer_id":52751924789479,"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-rose-jff-tire-1260856303.webp?v=1790988288","url":"https:\/\/ottawabikeandtrail.com\/products\/ultradynamico-rose-jff-tire","provider":"Ottawa Bike and Trail, LLC","version":"1.0","type":"link"}
