Cervelo Aspero Rival XPLR AXS 1 - 2026

In 2019, the Cervélo Áspero revolutionized the gravel world by introducing a speed- and performance-focused approach. This 2026 version remains true to that spirit while incorporating major upgrades: a threaded T47 bottom bracket for simplified maintenance, a universal SRAM UDH derailleur hanger compatible with new drivetrains, and cleaner cable routing. Aerodynamic optimization is primarily aimed at saving energy over long distances, a gain that can make all the difference on a windy day.

The lowered seatstays provide more compliance, and the slightly reduced front end stiffness makes long rides more comfortable. The increased mud clearance improves versatility, making the Cervélo Aspero Rival XPLR AXS 1 black/charcoal 2026 a fast, durable bike perfectly suited to the most demanding gravel events.
