The frame supports the \u003cb\u003eUniversal Derailleur Hanger (UDH)\u003c\/b\u003e, which rotates rearward in a crash to protect the derailleur. In 2022, an OSTRO Gravel finished \u003cb\u003etop-10 at Unbound 200\u003c\/b\u003e, gravel’s toughest race, in a year when heavy rain made the course brutal.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 11.0pt;\"\u003eWho It’s For\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp class=\"MsoListParagraph\" style=\"text-indent: -.25in; mso-list: l0 level1 lfo1; margin: 0in 0in 4.0pt .5in;\"\u003e\u003c!-- [if !supportLists]--\u003e\u003cspan style=\"mso-list: Ignore;\"\u003e•\u003cspan style=\"font: 7.0pt 'Times New Roman';\"\u003e        \u003c\/span\u003e\u003c\/span\u003e\u003c!--[endif]--\u003eGravel racers and fast all-road riders who want a race-focused frame, not an adventure or bikepacking platform.\u003c\/p\u003e\n\u003cp class=\"MsoListParagraph\" style=\"text-indent: -.25in; mso-list: l0 level1 lfo1; margin: 0in 0in 4.0pt .5in;\"\u003e\u003c!-- [if !supportLists]--\u003e\u003cspan style=\"mso-list: Ignore;\"\u003e•\u003cspan style=\"font: 7.0pt 'Times New Roman';\"\u003e        \u003c\/span\u003e\u003c\/span\u003e\u003c!--[endif]--\u003eRiders who want a fully electronic drivetrain with an integrated power meter.\u003c\/p\u003e\n\u003cp class=\"MsoListParagraph\" style=\"text-indent: -.25in; mso-list: l0 level1 lfo1; margin: 0in 0in 4.0pt .5in;\"\u003e\u003c!-- [if !supportLists]--\u003e\u003cspan style=\"mso-list: Ignore;\"\u003e•\u003cspan style=\"font: 7.0pt 'Times New Roman';\"\u003e        \u003c\/span\u003e\u003c\/span\u003e\u003c!--[endif]--\u003eRiders comfortable with an integrated cockpit rather than a swappable stem and bar.\u003c\/p\u003e\n\u003cp class=\"MsoListParagraph\" style=\"text-indent: -.25in; mso-list: l0 level1 lfo1; margin: 0in 0in 4.0pt .5in;\"\u003e\u003c!-- [if !supportLists]--\u003e\u003cspan style=\"mso-list: Ignore;\"\u003e•\u003cspan style=\"font: 7.0pt 'Times New Roman';\"\u003e        \u003c\/span\u003e\u003c\/span\u003e\u003c!--[endif]--\u003eNot the best fit if you need rack or frame-bag mounts for loaded touring.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 11.0pt;\"\u003eWhat to Look For\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp class=\"MsoListParagraph\" style=\"text-indent: -.25in; mso-list: l0 level1 lfo1; margin: 0in 0in 4.0pt .5in;\"\u003e\u003c!-- [if !supportLists]--\u003e\u003cspan style=\"mso-list: Ignore;\"\u003e•\u003cspan style=\"font: 7.0pt 'Times New Roman';\"\u003e        \u003c\/span\u003e\u003c\/span\u003e\u003c!--[endif]--\u003e\u003cb\u003eBottom bracket fit: \u003c\/b\u003estandard cups are CeramicSpeed T47A aluminum, with optional CeramicSpeed bearings for DUB, 24mm, or Ultra-Torque cranks.\u003c\/p\u003e\n\u003cp class=\"MsoListParagraph\" style=\"text-indent: -.25in; mso-list: l0 level1 lfo1; margin: 0in 0in 4.0pt .5in;\"\u003e\u003c!-- [if !supportLists]--\u003e\u003cspan style=\"mso-list: Ignore;\"\u003e•\u003cspan style=\"font: 7.0pt 'Times New Roman';\"\u003e        \u003c\/span\u003e\u003c\/span\u003e\u003c!--[endif]--\u003e\u003cb\u003eCockpit sizing: \u003c\/b\u003ethe Integrated Aero Barstem (reach 80mm, drop 120mm) comes in multiple lengths and widths; as a one-piece unit, dial in fit before ordering.\u003c\/p\u003e\n\u003cp class=\"MsoListParagraph\" style=\"text-indent: -.25in; mso-list: l0 level1 lfo1; margin: 0in 0in 4.0pt .5in;\"\u003e\u003c!-- [if !supportLists]--\u003e\u003cspan style=\"mso-list: Ignore;\"\u003e•\u003cspan style=\"font: 7.0pt 'Times New Roman';\"\u003e        \u003c\/span\u003e\u003c\/span\u003e\u003c!--[endif]--\u003e\u003cb\u003eTire and wheel intent: \u003c\/b\u003e45mm measured clearance, with wheels tuned most aero around 32mm but effective to 43mm.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 11.0pt;\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 8.0pt;\"\u003e\u003cb\u003eFrame and fork: \u003c\/b\u003eTeXtreme, Toray, and Nippon Graphite pitch-based carbon at \u003cb\u003e950g\u003c\/b\u003e, with the OSTRO Wide Stance Fork.
