Cervelo Aspero GRX RX610 Sea Ice

Cervélo Aspero GRX RX610 sea ice carbon gravel bike 12 speed 2025
The 2025 Cervélo Aspero GRX RX610 sea ice embodies the spirit of fast gravel riding, with sleek geometry and a design engineered for long-distance efficiency. True to the DNA of the Áspero range, this 2025 version benefits from an even more comfortable frame, improved mud clearance, and a cockpit compatible with multiple configurations. The adoption of a T47 threaded bottom bracket simplifies maintenance, while the UDH dropout allows for future drivetrain upgrades.

With its Shimano GRX RX610 double 12-speed chainring setup, this model prioritizes versatility and fluidity. Its smooth drivetrain, powerful brakes, tubeless-ready wheels, and 700x40c tires make it a bike capable of everything: from off-road exploration to road endurance. A gravel bike built to go far, fast, and in style.
