The all-new spero-5 was built for the front end of the race, and is the most aerodynamic gravel bike ever created. Cervlo has long been synonymous with aerodynamic performance, and weve brought that 30 years of expertise to gravel racing. The new bike is a stunning 37 Watts faster than the outgoing model, and 34 Watts faster than its nearest competitor. With clearance for 45mm tires, downtube storage, and a threaded bottom bracket, spero-5 is ready to race the second it rolls off the shop floor. The spero-5 made a rainbow-jersey debut under UCI Gravel World Champion Marianne Vos, and will be campaigned by some of the most elite bike racers in the world.

FEATURES:

• Shape of Speed: spero-5 is 37 Watts faster than its predecessor, and 34 Wattsfaster than the nearest competitor. Cervelo has long led the industry in aerodynamics, and weve delivered a gravel race bike worthy of that reputation. The aero handlebar and stem are responsible for nearly 6 Watts of that savings on their own.
• Weight: The new spero-5 is 66 grams lighter than its predecessor, despite adding a significant amount of surface area to improve aerodynamic performance.
• Mixed & Matched Tire Geometry: When fitted with equally-sized tires (e.g. 42mm front and rear), spero-5s handling is stable, confidence-inspiring, and ready for the roughest courses. To increase aerodynamics even further, and sharpen handling for less-technical courses, we optimized the geo for a 4mm tire width differential (e.g. 40mm front, 44mm rear).
• Downtube Storage: First seen on the P-Series triathlon bike, weve implemented ourindustry-leading downtube storage door on the Aspero-5. Its the lightest and most aerodynamically efficient system on the market, and puts a tube, tools, and a flat kit inside the frame and out of the wind.
