Cervelo has built a formidable reputation as a pioneer in aerodynamics, ride quality, and dependable performance. The Cervelo Aspero is ideal for those seeking a gravel race bike that transitions smoothly from road cycling. Although not designed as a one-size-fits-all solution, the Aspero impresses with its versatility across road, gravel, and XC trails. It is fast, capable, and fun, resembling a road bike more closely than any other gravel option available, ensuring an exhilarating experience for avid riders. This gravel frameset is crafted for intense single-day efforts, whether in training or racing, or for enjoyable 2-3 hour rides with friends on country roads and hardpack trails. The Aspero frameset features distinctive elements aimed at providing road cyclists with an engaging gravel riding experience.

The Aspero borrows its frame construction and features from various Cervelo models, yet it is specifically designed for gravel racing. It incorporates the Squoval.Max tube shapes seen in the R5, with influences from the S, and P series. Aerodynamics remain a key focus for Cervelo; the toptube mimics the P5, including a concealed 2-bolt SmartPak bag mount that accommodates various aero and storage bags. These internal design references showcase Cervelo's finest engineering efforts, all tailored to enhance the gravel racing experience through optimal fit, speed, balance, handling, and setup flexibility.

Further improvements include lowered seat stays for increased rear compliance and a slight reduction in front-end stiffness, easing the strain during the final hours of a long race. Additional clearance for mud was also incorporated, drawing on lessons from the R5-CX and the muddy conditions at Unbound 2023. These may seem like minor adjustments, but collectively, they significantly enhance the bike's performance. The outcome is a model that stays true to the original Áspero's essence but offers greater speed, comfort, and versatility.

The SRAM Rival XPLR AXS 1 component group is a highly specialized system designed to enhance the gravel cycling experience through technological innovation and streamlined functionality. This groupset is tailored specifically for single-chainring setups, which simplifies the mechanical complexity and reduces the weight—critical factors in gravel biking.

At the core of the Rival XPLR AXS 1 is SRAM's AXS wireless technology, which eliminates the need for traditional cables and housing. This system allows for quicker, cleaner, and more reliable shifting operations. The rear derailleur incorporates an integrated battery, facilitating seamless electronic shifts and offering a robust design optimized for the demands of rugged terrain. It features a clutch mechanism that maintains chain tension, drastically reducing chain slap and the risk of derailments.

The cassette in this groupset is designed with a wide gear range, accommodating the steep inclines and rapid descents typical of gravel routes. The shifters are ergonomically designed to enhance comfort and control, providing tactile feedback and precise control over gear selection, which is vital in variable terrain conditions.

Furthermore, the Rival XPLR AXS 1 includes hydraulic disc brakes, ensuring consistent and powerful braking capabilities, which are essential for maintaining control in diverse weather and surface conditions. Overall, the SRAM Rival XPLR AXS 1 offers a robust, efficient, and technologically advanced solution for modern gravel cyclists, focusing on performance, durability, and a clean aesthetic.
