Jonas Vingegaard, the celebrated two-time Tour de France champion, has recently made waves in the cycling world by adopting a unique set of 150mm cranks for his road bike during the Volta ao Algarve in February 2025. This decision is part of a growing trend among elite cyclists seeking biomechanical advantages through shorter crank lengths. As professional riders continuously push the boundaries of performance, Vingegaard’s choice serves as a noteworthy example of how equipment modifications can enhance cycling efficiency and comfort.
The shift to shorter cranks, such as Vingegaard's 150mm, is driven by several biomechanical benefits. One of the most significant advantages is the reduction in knee flexion at the peak of the pedal stroke. Traditional crank lengths often force riders into aggressive positions that can increase the risk of knee injuries. By using shorter cranks, Vingegaard can maintain a more efficient pedal stroke while minimizing strain on his joints, particularly during long climbs or high-intensity efforts.
Aerodynamics play a crucial role in competitive cycling, and shorter cranks can facilitate a more aerodynamic riding position. This is particularly important for professional cyclists who rely on every possible advantage during high-speed races. With a lower torso and a tighter position, cyclists can reduce drag, which is essential for maintaining speed and power output. Vingegaard's customization of his cranks is indicative of the tailored approach many athletes take; since major manufacturers like SRAM do not typically produce cranksets shorter than 160mm, Vingegaard's choice likely reflects a specific fit to his body and riding style.
Performance implications of shorter cranks include changes in cadence and power output. By shifting to a higher cadence, cyclists can achieve the same gear ratio with less muscle fatigue. Interestingly, research indicates that crank length within a range of 80mm to 300mm has minimal impact on maximum power output. This finding suggests that while Vingegaard may be sacrificing some raw power potential, the benefits of reduced joint stress and enhanced comfort during aggressive riding positions could very well outweigh any perceived downsides.
The trend toward shorter cranks is not exclusive to Vingegaard. Riders on his Team Visma-Lease a Bike, such as Wout van Aert, have also begun to experiment with shorter lengths, opting for 160mm or 165mm as a compromise. This movement highlights a broader shift in professional cycling where athletes are looking beyond traditional equipment to optimize their performance through innovative adaptations. Tadej Pogačar, a close competitor of Vingegaard, has similarly transitioned from 172.5mm to 165mm cranks, reflecting an awareness of the advantages that shorter cranks can bring in terms of cadence and aerodynamics.
Historically, the adoption of shorter crank lengths has been a gradual evolution in cycling, with prominent figures like Bradley Wiggins leading the charge. Wiggins notably switched from 177.5mm to 170mm cranks prior to his 2015 hour record attempt, using this change to improve his aerodynamics and fit. As more cyclists embrace technology and sports science, the use of shorter cranks could become a standard practice, influencing even amateur cyclists who aspire to enhance their performance.
While the benefits of shorter cranks are clear, some debates linger regarding their impact on maximum power output. Critics may argue that extremely short cranks could limit a cyclist's ability to generate peak power. However, the focus for professional cyclists often shifts from raw power to efficiency and sustainability over long races. The reduction in joint stress and improved recovery times can lead to better performance in the long run, ultimately enhancing a rider's capabilities over challenging tours and competitions.
Vingegaard's switch to 150mm cranks is more than just a personal preference; it represents a significant shift in the cycling landscape towards customization and a deeper understanding of biomechanics. As technology continues to evolve and more cyclists explore the benefits of shorter crank lengths, we may witness a new era in cycling performance where comfort and efficiency are prioritized alongside speed and strength. By making bold choices like this, athletes like Vingegaard are not only redefining their own limits but also setting new standards for the sport as a whole.
