Yes, clipless pedals can improve power output by approximately 10%, but only under specific conditions—and that’s the crucial caveat researchers want you to know. Recent studies show that the 10% figure applies almost exclusively to short, maximum-effort sprints and climbing, where riders are pushing their hardest against resistance. However, the title “New Research Says Less” captures the reality: this advantage doesn’t translate to everyday recreational cycling, where most riders spend most of their time.
A rider grinding up a steep climb might genuinely benefit from the extra power a clipless system provides, but that same rider on a flat stretch of road at a steady pace will see no meaningful efficiency gains. The confusion around this statistic persists because marketing has long promised universal benefits from clipless pedals, while the actual science reveals a much narrower advantage. Understanding where clipless pedals actually help—and more importantly, where they don’t—is essential before investing in shoes, cleats, and bike modifications.

Does the 10% Sprint Power Claim Actually Hold Up?
The 10% improvement figure is real, but context matters enormously. Research from Fort Hays State University found a statistically significant 5.3% increase in maximum power output when cyclists switched from flat to clipless pedals. Mountain bike Action Magazine’s field test went further, documenting a 16.6% increase in maximum sprint power during short bursts. These aren’t marketing claims—they’re documented results from controlled testing.
The common thread: all of these tests involved maximum-effort sprints lasting 30 seconds or less, where a rider is trying to generate their absolute highest wattage. The mechanism is straightforward: clipless pedals allow you to pull up on the pedals as well as push down, theoretically engaging more muscle groups and distributing force more effectively across the pedal stroke. During an all-out sprint, when every watt matters, this additional leverage can produce measurable gains. However, a critical counterpoint emerged from BikeRadar’s comparative testing, which found essentially no difference between systems: 406 watts on clipless versus 408 watts on flat pedals during high-intensity sprints. The variability suggests that rider technique, bike setup, and individual physiology may matter as much as the equipment itself.
The Climbing Advantage—Where Clipless Pedals Make Their Best Case
Climbing is where clipless pedals show their most consistent benefit, and the data is persuasive. Research from the University of Nevada, Las Vegas, documented that riders averaged 20.2 watts higher power output on climbs when using clipless pedals compared to flat pedals. Even more compelling for practical purposes: test riders were approximately 26.4 seconds faster on a climbing effort with clipless systems. For a cyclist tackling a three-minute climb, that’s meaningful—not just in raw numbers but in perceived effort and real-world performance.
The climbing advantage likely stems from the pulling-up component of the pedal stroke becoming more relevant when fighting gravity. On a steep grade, the ability to engage hamstrings and hip flexors more effectively throughout the entire revolution appears to translate into sustained power production. This differs from sprinting, which is brief and explosive; climbing is about maintaining force over a longer duration, and that’s where the pulling-up motion gains significance. Still, individual results vary, and this advantage presumes proper cleat positioning and rider adaptation to the system.
The Steady-State Riding Reality—Where Power Gains Disappear
Here’s the fact that often gets buried in product reviews: there is no discernable difference in efficiency between clipless and flat pedals during constant-power, steady-state riding. Cycling UK’s research on this topic found that recreational cyclists maintaining a steady pace on flat terrain showed identical efficiency metrics regardless of pedal type. This applies to the majority of casual rides—the Sunday spin, the commute to work, the long, easy group ride. The reason is biomechanical.
At steady-state intensities, most riders naturally use a pushing-dominant pedal stroke anyway. The pulling-up phase contributes minimally to power production when you’re not at maximum effort. This is why a recreational rider investing in clipless pedals should not expect their average speed to increase or their legs to feel less fatigued on normal rides. The equipment change won’t hurt, but it won’t offer a performance boost where you spend the most time riding.
Why the Conditions Matter So Much—The Missing Context in Most Claims
The reason the “10% improvement” claim persists despite being partially false is that researchers and marketers often fail to specify the testing conditions. A 10% gain in maximum sprint power is genuinely useful for competitive cyclists, track racers, and mountain bikers tackling technical terrain. It’s not useful for the person riding 12 miles per week on flat routes. The same equipment can be both “effective” and “not applicable to you,” depending on how you ride.
Cleat positioning, shoe stiffness, pedal engagement angle, and rider technique all modify the results. A poorly-positioned cleat can eliminate any advantage or even reduce power output compared to flats. A rider who’s spent years on flat pedals and hasn’t developed the neuromuscular adaptation to an upstroke may not see any power improvement, even on climbs, until they’ve trained with the system for weeks. The science is real, but individual results are genuinely variable.
Beyond Power Output—The Hidden Costs and Trade-Offs
Power production is just one metric in the larger equation of cycling performance and enjoyment. Clipless pedals impose real limitations that research doesn’t typically quantify. You cannot simply put your foot down quickly on flat terrain; you must unclip, which takes time and carries the risk of falling over at a standstill if you forget. For urban cycling, mountain biking on technical terrain, or beginner riders, this drawback often outweighs any power advantage.
There’s also a financial and maintenance burden. Clipless pedals, cleats, and specialized shoes cost significantly more than flats. Cleats wear down and must be replaced periodically. The system requires consistent practice to avoid embarrassing stops at traffic lights. For someone who cycles once a week, the 10% power improvement on rare climbs rarely justifies the equipment investment, adaptation time, and increased complexity.
The Variability Question—Why Two Studies Can Show Opposite Results
The contradiction between the 16.6% improvement in one test and the 406-versus-408-watt equivalence in another isn’t a failure of research; it’s a reflection of how sensitive these measurements are to individual factors. Body weight, leg length, calf flexibility, core strength, and riding position all influence whether clipless systems benefit a particular cyclist. A lightweight climber might gain 20% on hills; a powerful sprinter with excellent technique on flats might see zero change.
This variability is why broad product claims (“10% faster!”) can feel simultaneously true and false. They’re true for some riders under specific conditions and false for others in different contexts. The honest assessment: clipless pedals improve maximum power output in short, hard efforts for riders who use proper technique. Everyone else should evaluate based on whether they actually need that advantage and whether they enjoy the riding style.
What This Means for Your Cycling Future
As cycling technology evolves, the pedal-type question is becoming less polarized. Modern flat pedals have improved dramatically, offering better foot retention and feedback than older designs. Simultaneously, clipless systems have become more accessible and user-friendly. The real trend in cycling research is that equipment matters less than consistency, training, and proper fit.
A recreational rider on flat pedals who rides three times a week will likely outperform an occasional clipless rider. The future of research into this topic will likely focus less on absolute power comparisons and more on which system suits which disciplines and riders. Mountain biking has largely moved back toward flats or hybrid systems; road cycling and gravel racing continue to favor clipless; commuting and casual cycling increasingly use platform pedals with aggressive grip. The 10% claim will probably persist in marketing, but the nuanced answer—”it depends on what you’re trying to do”—is what the science actually shows.
Conclusion
The claim that clipless pedals improve power output by 10% is accurate, but incomplete. Research confirms approximately 10% maximum power gains during sprints and around 20 watts extra on climbs—meaningful advantages for competitive or hard-effort riding. However, these gains don’t apply to steady-state, recreational riding, where efficiency is identical between pedal types. The “New Research Says Less” part of the conversation acknowledges that for most cyclists, the real-world benefits are far narrower than marketing suggests.
Before switching to clipless pedals, ask yourself whether you regularly sprint, climb steep grades, or race competitively. If you do, the research supports trying them. If you ride for fitness, commuting, or casual enjoyment on relatively flat terrain, the data suggests you won’t experience meaningful performance gains. Clipless pedals aren’t bad—they’re just not universally beneficial, and that’s what the science actually says.
