Cervelo has cemented its status as a leader in aerodynamics, ride quality, and reliability, now channeling this expertise into the gravel biking realm. The Cervelo Aspero is perfectly suited for those seeking a gravel bike that offers a seamless shift from road cycling. Designed not to be a universal solution but rather a specialized choice, the Aspero excels in its adaptability on road surfaces, gravel paths, and XC trails. Its swift, robust, and enjoyable ride closely mirrors that of a road bike, more so than any other gravel model, providing a thrilling ride for enthusiasts. This gravel frameset is tailored for vigorous single-day endeavors, be it training or racing, or for leisurely 2-3 hour outings with friends on country lanes and compacted trails. The Aspero frameset includes unique features that cater specifically to the needs of road cyclists seeking a dynamic gravel cycling experience.

In its construction, the Aspero integrates elements from various Cervelo models but is explicitly engineered for gravel racing. It features the Squoval.Max tube shapes from the R5, drawing design influences from the S, and P series. Aerodynamics continue to be a major emphasis; the toptube echoes the P5 and includes a hidden 2-bolt SmartPak bag mount compatible with a range of aero and storage bags. These design choices highlight Cervelo's top engineering achievements, all focused on optimizing the gravel racing experience through enhanced fit, speed, balance, handling, and versatile setup options.

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 Shimano GRX RX610 1 groupset represents a significant advancement in gravel-specific cycling technology, meticulously designed to tackle the challenging and varied terrain of gravel riding. Engineered for single chainring setups, this component group highlights Shimano's commitment to refining ride performance under the rigors of off-road conditions.

The centerpiece of the GRX RX610 1 is its robust and reliable crankset, which features an optimally spaced single chainring to handle a broad spectrum of gradients and surface irregularities. This design simplifies shifting mechanisms and reduces the potential for mechanical issues, making it ideal for the unpredictability of gravel paths. Accompanying the crankset is a wide-range rear derailleur that supports up to a 42-tooth cog, allowing for smoother transitions between gears even under heavy load and steep ascents.

Shimano has also redefined ergonomics with the GRX RX610 levers, which provide enhanced lever access and control. The lever hoods are textured for increased grip in wet conditions, and the brake lever pivot has been adjusted to offer a more responsive braking feel, crucial for navigating slippery surfaces. Additionally, the groupset includes hydraulic disc brakes that deliver consistent stopping power and modulation, essential for maintaining control on loose or wet terrain.

Overall, the Shimano GRX RX610 1 is a testament to Shimano's innovation in creating a gravel-specific groupset that meets the dynamic needs of modern gravel cyclists, emphasizing durability, efficiency, and ergonomic comfort.
