🌪️ Go Fast. Stay Composed. Gravel Performance Reimagined.

The 2025 Cervélo Áspero GRX RX610 takes everything that made the original Áspero a gravel icon and refines it with real-world enhancements for comfort, compatibility, and confidence over long miles. It’s still a race-first gravel bike—but now it's even better for riders chasing podiums, personal bests, or just a high-speed escape from pavement.

This build pairs Shimano’s GRX RX610 12-speed drivetrain with a wide-range 46/30T crankset and 11-36T cassette, giving you the gear spread to climb, fly, and descend with control. The T47a threaded bottom bracket, SRAM UDH-compatible hanger, and internal cable routing make this Áspero more user-friendly and future-proof than ever—ready for whatever drivetrain you throw at it next.

Why You’ll Love It:

✔ Race Geometry Meets Real-World Comfort – Dropped seatstays + tweaked stiffness = fast and forgiving.
✔ Shimano GRX RX610 2x12 – Road-meets-gravel gearing to crush climbs, spin smooth, and descend strong.
✔ Threaded T47a BB – Pro stiffness, home mechanic serviceability.
✔ UDH-Compatible – Future-ready for SRAM Transmission drivetrains.
✔ Aero-Enhanced Frame – Subtle drag savings over the previous model mean less fatigue, more speed.
✔ Mud-Clearing Tire Clearance – Fits up to 700x44c tires (measured) with room to spare.
