This detailed comparison review dives into the nuances of Speedplay's Aero and Zero pedals, two top contenders in the cycling world. We explore the key differences that set these pedals apart, focusing on design, functionality, and user experience. From the single-sided design of the Aero versus the double-sided Zero, to the impact on weight, drag, and ease of clipping in and out, we analyze the strengths and weaknesses of each. Our review considers both the immediate impressions and the long-term performance, factoring in considerations such as break-in periods and the implications for different cycling disciplines.This comprehensive analysis examines the practical implications of choosing one pedal over the other. We'll delve into the importance of Q-factor consistency, particularly when switching between bikes, and discuss the convenience factors of each design for various cycling styles, from everyday rides to competitive time trials. Ultimately, this review aims to help you determine which Speedplay pedal best suits your individual riding needs and preferences, enabling you to make an informed decision based on a thorough understanding of their respective advantages and disadvantages.
Pros And Cons
- Lightweight (due to titanium axle)
- Offers different spindle lengths (titanium version)
- Uses a hex key hole for easier maintenance
- Shares the same Q-factor as Speedway pedals, facilitating bike switching
- Single-sided design, making it potentially inconvenient for frequent on/off mounting

Single-Sided vs. Double-Sided Design
The most significant difference between the Speedplay Aero and Zero pedals lies in their design. The Aero is a single-sided pedal, meaning only one side is functional for clipping in, while the Zero is double-sided. This single-sided design might be a drawback if you frequently mount and dismount your bike. However, for time trials or short bursts of activity, it poses less of an issue.
The Aero's single-sided platform features a plastic dimpled surface that directly interacts with the cleat. The Zero, on the other hand, provides a double-sided platform with a more traditional feel. Both utilize the same Walkable cleat, simplifying the transition between bikes.
For those constantly clipping in and out, the double-sided Zero offers more convenience. However, the Aero’s design focuses on reducing weight and drag, potentially beneficial for competitive cycling scenarios.
Titanium Axle and Q-Factor Considerations
I chose the titanium axle version of the Speedplay Aero not primarily for weight reduction, though it does contribute. The key reason is the availability of different spindle lengths, notably a shorter one with the titanium option.
This shorter spindle on the titanium Aero pedal allows for a more consistent Q-factor (distance between pedals) with my Speedplay Zero pedals. Maintaining the same Q-factor is important when switching bikes, improving consistency and comfort.
The titanium version also features a hex key hole on the other side, similar to Shimano pedals, making adjustment easier than the 15mm pedal spanner required for the steel version.
Clipping In and Pedal Break-In
Initially, the Speedplay Aero pedals proved challenging to engage, requiring significant practice. This contrasts with the easier engagement of the double-sided Zero pedals.
However, after a break-in period, the Aero pedals' engagement became smoother and comparable to the Zero pedals. This suggests that the stiffness of a new Aero pedal might be a temporary issue, easing over time.
The initial difficulty highlights the potential learning curve associated with the Aero's single-sided design. Once broken in, this difficulty largely disappears.
Overall Conclusion and Recommendation
The Speedplay Aero pedals, despite their initial stiffness and single-sided design, ultimately offer a comparable experience to the Zero pedals after a break-in period. The benefits of weight reduction and consistent Q-factor are significant, especially for time trial riding.
The single-sided nature might be a drawback for frequent mounting and dismounting, making the double-sided Zero a more convenient option for general cycling. However, for specialized uses like time trials, the Aero’s aero advantage could outweigh the inconvenience.
Ultimately, the best choice depends on individual needs and preferences. For competitive time trial cyclists prioritizing marginal gains, the Speedplay Aero is a strong contender. For everyday cyclists, the Speedplay Zero might be the more practical choice.
