Cervélo Áspero GRX RX827 Di2

The Cervélo Áspero remains true to its original brief as a gravel bike built for performance and versatility, but this generation builds on that foundation with meaningful refinements that add up to a machine that's faster, more comfortable, and more capable across varied terrain. True to Cervélo's philosophy, aerodynamic improvements on the Áspero aren't about pure speed through drag reduction, they're about energy conservation. After a big day fighting headwind, the three watts saved might mean one less energy gel your stomach has to process. That's the Áspero mindset: practical performance for real-world gravel riding.

Every refinement serves this purpose. A threaded T47a bottom bracket—the asymmetrical design pioneered on the R5-CX—delivers the benefits of BBRight in a more rider-serviceable, user-friendly form. Neater cable routing maintains clean aesthetics while improving functionality. 

The frame geometry has been carefully evolved. Dropped seatstays increase rear compliance, smoothing rough terrain without sacrificing responsiveness. Reduced front-end stiffness takes the edge off during the final hours of long races, making extended efforts more sustainable. Between the dropped seatstays sits additional mud clearance, lessons learned from the R5-CX platform and validated through real-world conditions like the legendary Unbound mudfest. The aerodynamic refinements across the frame deliver measurable gains that translate to energy conservation over the course of a full day.
