In 2019, the Áspero revolutionized the gravel biking scene, ushering in a "new era of speed" that blended exhilaration with efficiency. Staying true to its roots, the latest Áspero model enhances its design with key updates: a threaded bottom bracket shell for increased durability, cleaner cable routing for a sleeker look, and a Universal Derailleur Hanger (UDH) compatible with SRAM’s latest drivetrains. Additionally, the new Áspero boasts improved aerodynamics—not merely to cut through the wind faster, but to conserve energy more effectively. The minor aerodynamic gains could mean saving the energy equivalent of one less gel after a grueling day against the wind—certainly a worthwhile trade.

Further refinements include lowered seat stays for added compliance, slightly reduced front-end stiffness to ease fatigue in long races, and increased mud clearance inspired by insights from the R5-CX and the challenging conditions at Unbound 2023. These enhancements, though subtle, collectively elevate the Áspero. The result is a bike that remains faithful to the feel of the original yet offers faster, more comfortable, and more versatile performance.

 

 

 

 

 

 

 

 

 

Key Features of the Aspero

Threaded Bottom Bracket: The Aspero incorporates the innovative T47a threaded bottom bracket first introduced on the R5-CX. This asymmetrical design is not only simple and rider-serviceable but also combines the advantages of the BBRight system in a more user-friendly format.

Universal Derailleur Hanger: Embracing SRAM's Universal Derailleur Hanger (UDH), the new Aspero ensures future-proof compatibility with current and upcoming SRAM Transmission drivetrains. It's the perfect setup for those who like a bit of 'business in the front, party in the back' style.

Internal Cable Routing: Aspero benefits from the same bearing dimensions used in the R5, Soloist, R5-CX, and Caledonia models. This compatibility allows the use of various bearing caps and stems. For those seeking a sleek, race-ready appearance, the ST31 stem and HB13 handlebar from the R5 are ideal for achieving a fully internal look.
