{"product_id":"orbea-orca-aero-m21e-ltd","title":"Orbea Orca Aero M21E LTD","description":"\u003cp\u003eThe Orbea Orca Aero M21E LTD represents a fundamental shift in how aerodynamic road bikes are engineered. Rather than optimizing the frame in isolation, Orbea developed the Orca Aero as a complete bike-rider system, where every design decision considers how the bicycle interacts with the rider in motion. The result is a machine that saves measurable watts not just in the wind tunnel, but in real-world racing conditions where varied wind angles and rider dynamics determine victory.\u003c\/p\u003e\n\u003cp\u003eDevelopment began with meticulous aerodynamic refinement at the component level. The head tube is shaped to be as narrow and sharp as possible while maintaining a standard steerer tube, reducing frontal area without complex solutions. The optimized fork integrates seamlessly with the downtube regardless of tire width or wind yaw angle. The wider downtube profile manages airflow more efficiently and works in conjunction with new flush bottle cages to further enhance system efficiency. The slimmer seat tube reduces drag while maintaining structural efficiency, while thinner seatstays with a lower attachment point optimize stiffness-to-weight ratio while providing vertical compliance. The bottom bracket keel structure significantly enhances aerodynamic performance through this critical transition area. Combined, these refinements deliver 5.1 watts of drag reduction at 50 km\/h, consistent across all speeds and wind angles.\u003c\/p\u003e\n\u003cp\u003eBut aerodynamics alone isn't enough. The Orca Aero's total system approach extends to rider positioning. The 78mm bottom bracket drop, the lowest on the market, positions the rider lower for improved stability and control at high speeds, while directly reducing frontal area exposed to wind. Extensive cockpit options including 13 handlebar sizes and up to 40mm of spacers allow riders to find their ideal aerodynamic position. Two seatpost offset options and a reversible clamp provide further customization. The result: approximately 14 watts saved while riding at 50 km\/h on flat terrain through a more stable, aerodynamic rider position.\u003c\/p\u003e\n\u003cp\u003eThe OMX carbon monocoque frame delivers lateral stiffness for direct power transfer during accelerations and sprints. Size-specific fork tuning ensures consistent handling across the entire size range. Generous tire clearance accommodates up to 37mm tires while saving 6-7 watts on rough surfaces. Di2 integration and the universal UDH derailleur hanger ensure modern compatibility. SRAM Force AXS provides wireless electronic shifting, while Oquo Road Performance RP50LTD wheels complete this race-focused package.\u003c\/p\u003e\n\u003cp\u003eThe Orca Aero is engineered for Grand Tours, spring classics, and fast road racing—where aerodynamic efficiency and responsive handling define champion performance.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame - \u003c\/strong\u003eOrbea Orca Aero Carbon OMX monocoque disc, BB386, internal cable routing, 12mm thru-axle, aero-keel bottom bracket\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrivetrain - \u003c\/strong\u003eSRAM Force AXS 12-speed wireless\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheelset - \u003c\/strong\u003eOquo Road Performance RP50LTD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Orbea Bikes","offers":[{"title":"Golden Off White - Sunset (Gloss) \/ 47","offer_id":48322823979253,"sku":"U12447AV","price":8268.0,"currency_code":"USD","in_stock":true},{"title":"Royal Plum (Matt) - Fantasy Purple C.
