The Cervelo Aspero-5 is the most aerodynamic gravel bike ever created, built for the front end of the race. Drawing on 30 years of aerodynamic expertise, Cervelo has translated its road racing performance philosophy into a gravel platform that demands respect. The results speak for themselves: 37 watts faster than its predecessor and 34 watts faster than its nearest competitor. This is not a compromise bike, it&';s a purpose-built racing machine that made its rainbow-jersey debut under UCI Gravel World Champion Marianne Vos and will be campaigned by some of the most elite gravel racers in the world. The foundation is Cervelo&';s all-carbon frame, engineered for speed without sacrificing the capability required for demanding gravel courses. At just 66 grams lighter than its predecessor despite adding significant surface area for aerodynamic performance, the Aspero-5 proves that speed and efficiency can coexist. The frame accommodates 45mm tires, giving you total freedom to choose traction and comfort appropriate to any course conditions. Aerodynamic sophistication defines this platform. The aero handlebar and stem combination alone accounts for nearly 6 watts of performance savings. The completely internal cable routing eliminates drag disruption, while refined tube shapes minimize wind resistance at the speeds where gravel racing truly happens. The innovative downtube storage, first seen on Cervelo&';s P-Series triathlon platform, is the lightest and most aerodynamically efficient system available, securely storing a tube, tools, and flat kit inside the frame and completely out of the wind. The geometry has been optimized for modern gravel racing demands. Run equally-sized tires (42mm front and rear) for stable, confidence-inspiring handling on rough courses, or leverage the optimized 4mm tire width differential (40mm front, 44mm rear) for sharpened aerodynamics and handling precision on less-technical terrain. A threaded bottom bracket provides standard compatibility and reliability, while industry-leading engineering ensures this bike is ready to race the moment it leaves the shop.
