The 2024 Aspero features improvements that 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 RX820 component group is an advanced, integrated system specifically designed for gravel cycling, providing superior performance and reliability in off-road conditions. This series marks a significant enhancement in Shimano's gravel-specific lineup, combining robust durability with refined ergonomics and precision.

The GRX RX820 features a dual chainring setup, which is a critical component for riders requiring a broader gear range to tackle varied landscapes effectively. The front derailleur's design accommodates wider tires and greater frame variability, ensuring compatibility with the diverse designs found in modern gravel bikes. The rear derailleur incorporates Shimano's renowned Shadow RD+ technology, which stabilizes the chain across rough terrain, reducing chain slap and the risk of derailment.

Shimano has engineered the RX820 levers with an ergonomic design that prioritizes comfort and control. These levers are equipped with an anti-slip texture and a revised pivot location to enhance lever accessibility and braking precision, vital for maintaining control on slippery or uneven surfaces. Additionally, the system includes hydraulic disc brakes, which are essential for consistent, powerful braking performance in all weather conditions.

Furthermore, the RX820 groupset integrates seamlessly with Shimano's digital Di2 shifting system, offering crisp, fast, and reliable gear changes at the push of a button. This electronic shifting mechanism is particularly beneficial in the unpredictable environments of gravel riding, where quick and precise gear changes can significantly impact rider performance and comfort. Overall, the Shimano 2024 GRX RX820 provides a comprehensive solution for the demanding needs of gravel cyclists, emphasizing efficiency, stability, and ease of use.
