"Haul ass, not cargo"
A New Era of Speed in Gravel
In 2019, Áspero took the gravel world by storm, heralding a "new era of speed in gravel." Fun, but flat out.
The new Áspero remains true to its original brief, but with some improvements: a threaded BB shell, neater cable routing, and a UDH-compatible derailleur hanger. And it's more aero, of course—saving three watts over the previous generation.
In addition to the drag reduction, we also dropped the seat stays to give a bit more compliance out back, and reduced front-end stiffness slightly to make the last hours of a long race less painful. Between those dropped seat stays, we added in a bit more clearance for mud, too.
Shimano GRX RX820 - Mechanical Precision
Traditional Reliability: Shimano GRX RX820 12-speed mechanical shifting offers the tactile feedback and proven reliability many riders prefer. No batteries to charge, no electronics to worry about—just precise, dependable shifting powered by cables.
The 2x drivetrain with 48/31T chainrings paired with an 11-36T cassette provides versatile gearing for all terrain. Smaller steps between gears than a 1x setup, with a wide enough range for steep gravel climbs and fast road sections.
Key Innovations
Threaded Bottom Bracket
Aspero uses the asymmetrical T47a threaded bottom bracket pioneered on R5-CX. It's a simple, rider-serviceable interface that delivers BBRight benefits in a user-friendly form.
Universal Derailleur Hanger
SRAM's UDH standard ensures compatibility with current and future drivetrains. Ready for upgrades whenever you are.
Internal Cable Routing
Shares bearing dimensions with R5, Soloist, R5-CX, and Caledonia. Use any combination of bearing caps and stems for your preferred setup.
