Factor’s engineers spent extensive time refining the head tube shape, reducing drag at typical gravel speeds and manipulating airflow around the frame. The result? A frameset that saves minutes, not seconds, getting you to the finish line faster in real-world racing conditions.\u003c\/p\u003e\n\n\u003ch3\u003eVersatile Geometry and Tyre Clearance\u003c\/h3\u003e\n\n\u003cp\u003eWith 45mm tyre clearance on both 700c and 650b wheels, the OSTRO Gravel frame and forks can handle the muddiest, roughest, and most technical terrain. The steering geometry is designed around tyre size, ensuring precise handling whether using a 32mm all-road tyre or a 43mm gravel tyre. A lower bottom bracket, short chainstays, and optimised head tube angle provide a nimble, responsive ride without sacrificing stability, even on challenging off-road courses.\u003c\/p\u003e\n\n\u003ch3\u003eUDH Compatible\u003c\/h3\u003e\n\n\u003cp\u003eThe OSTRO Gravel Frame features a Universal Derailleur Hanger (UDH), perfect for fitting the latest SRAM 13-speed XPLR wireless groupsets while protecting your drivetrain in crashes. \u003c\/p\u003e\n\n\u003ch3\u003eIntegrated Bar-Stem\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eFrame size 49cm: Bar width: 38cm \/Stem length: 90mm\u003c\/li\u003e\n\t\u003cli\u003eFrame size 52cm: Bar width: 38cm \/Stem length: 90mm\u003c\/li\u003e\n\t\u003cli\u003eFrame size 54cm: Bar width: 40cm \/Stem length: 100mm\u003c\/li\u003e\n\t\u003cli\u003eFrame size 56cm: Bar width: 40cm \/Stem length: 100mm\u003c\/li\u003e\n\t\u003cli\u003eFrame size 58cm: Bar width: 40cm \/Stem length: 110mm\u003c\/li\u003e\n\t\u003cli\u003eFrame size 61cm: Bar width: 40cm \/Stem length: 110mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Factor","offers":[{"title":"49cm \/ Heritage Blue","offer_id":54293535818074,"sku":"1977290","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"52cm \/ Heritage Blue","offer_id":54293535850842,"sku":"1977291","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"54cm \/ Heritage Blue","offer_id":54293535883610,"sku":"1977292","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"56cm \/ Heritage Blue","offer_id":54293535916378,"sku":"1977293","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"58cm \/ Heritage Blue","offer_id":54293535949146,"sku":"1977294","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"61cm \/ Heritage Blue","offer_id":54293535981914,"sku":"1977295","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"49cm \/ Olive Green","offer_id":54293536014682,"sku":"1977296","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"52cm \/ Olive Green","offer_id":54293536047450,"sku":"1977297","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"54cm \/ Olive Green","offer_id":54293536080218,"sku":"1977298","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"56cm \/ Olive Green","offer_id":54293536112986,"sku":"1977299","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"58cm \/ Olive Green","offer_id":54293536145754,"sku":"1977300","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"61cm \/ Olive Green","offer_id":54293536178522,"sku":"1977301","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"49cm \/ UD Gloss","offer_id":54293536211290,"sku":"1977302","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"52cm \/ UD Gloss","offer_id":54293536244058,"sku":"1977303","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"54cm \/ UD Gloss","offer_id":54293536276826,"sku":"1977304","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"56cm \/ UD Gloss","offer_id":54293536309594,"sku":"1977305","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"58cm \/ UD Gloss","offer_id":54293536342362,"sku":"1977306","price":5499.0,"currency_code":"GBP","in_stock":true},{"title":"61cm \/ UD Gloss","offer_id":54293536375130,"sku":"1977307","price":5499.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/0827\/5290\/files\/Factor-Ostro-Gravel-Frameset-Heritage-Blue.jpg?v=1781189585","url":"https:\/\/checkout.sigmasports.com\/products\/ostro-gravel-frameset-16dol","provider":"Sigma Sports","version":"1.0","type":"link"}
