Product Details
The Cervélo Áspero GRX RX820 represents the evolution of gravel racing excellence, building upon the groundbreaking platform that first set new standards for gravel speed in 2019. This latest iteration introduces key refinements that elevate performance across every aspect of gravel riding, from competitive racing to epic adventure routes. Enhanced cable routing creates a cleaner, more aerodynamic profile while improving overall ride efficiency, complemented by a UDH-compatible derailleur hanger that ensures broad compatibility with modern drivetrain systems.
Aerodynamic advancement takes center stage with the updated Áspero's focus on energy conservation at high speeds. The refined design potentially eliminates the need for that extra energy gel after battling headwinds all day, ensuring every ounce of effort translates directly into forward motion. Meticulous attention to aerodynamic detail allows the Áspero to slice through air with remarkable efficiency, reducing drag and optimizing performance whether racing against competitors or chasing personal records on open gravel roads.
Comfort receives equal attention through redesigned seat stays and reduced front-end stiffness, drawing from Cervélo's extensive R5-CX experience and lessons learned from demanding events like Unbound. These changes deliver a noticeably smoother ride over rough terrain while improved mud clearance keeps the bike performing in adverse conditions. The Shimano GRX 12-speed drivetrain provides precise shifting across varied terrain, while Fulcrum Rapid Red 300 wheels and WTB Vulpine TCS tires complete the package with reliable performance and confident grip.
Perfect for riders seeking a versatile gravel machine that excels in racing scenarios while remaining capable for long-distance adventures, the Áspero GRX RX820 preserves the original's legendary speed while adding enhanced comfort and adaptability for tackling any gravel challenge with confidence.
