How to Master the Cycling Best Cadence for Speed

When cyclists talk about performance, speed and power often take center stage. But there’s one factor that’s just as important—cycling best cadence. Your cadence, or the rate at which you pedal (measured in revolutions per minute, RPM), plays a huge role in efficiency, endurance, and even injury prevention.
Maybe you’ve wondered: Should I pedal faster with less force, or slower with more torque? Finding the answer isn’t just about numbers; it’s about discovering your ideal pedaling rhythm that balances comfort, power, and energy conservation.
This guide will walk you through everything you need to know—from the optimal cycling cadence for different riders, to cadence drills for cyclists, and even the science behind the cycling power and cadence relationship. By the end, you’ll have practical strategies to improve your ride, whether you’re training for a race or just cruising around town.
What Is Cadence in Cycling?
Cadence simply means how fast you’re spinning your pedals. It’s measured in RPM—the number of pedal revolutions completed in one minute.
- A cadence of 90 RPM means your foot makes 90 complete circles in a minute.
- A cadence of 60 RPM is slower, requiring more muscular effort with each pedal stroke.
Cyclists often debate which is better—fast and light, or slow and strong. The truth? It depends on your fitness level, terrain, and goals.
Optimal Cycling Cadence Explained
The term optimal cycling cadence refers to the cadence range that maximizes your efficiency while minimizing fatigue. For most trained cyclists, this sweet spot lies between 85–95 RPM on flat terrain.
Why this range? Because it reduces muscular strain while allowing your cardiovascular system to take on more of the workload. You’re less likely to burn out your legs, which is crucial in long rides or competitive events.
Professional riders often hover around this range, but recreational cyclists may find comfort slightly lower—closer to 70–80 RPM.
Finding Your Ideal Pedaling Rhythm
Every rider has an ideal pedaling rhythm that feels natural and sustainable. This isn’t always the textbook number. Some prefer spinning quickly, while others rely on slower, more forceful strokes.
A good way to test it:
- Ride on a flat road and maintain different cadences (70, 80, 90, 100 RPM) for five minutes each.
- Track your heart rate, perceived effort, and average speed.
- Compare which cadence feels the most efficient over time.
“When I first started, I thought grinding out a heavy gear was better. But once I trained at 90 RPM, my endurance skyrocketed.”
This real-world experience mirrors what science suggests: cadence isn’t one-size-fits-all—it’s about finding balance.
Bike Cadence Training for Performance Gains
Bike cadence training can help you unlock efficiency, improve endurance, and even boost sprinting ability.
Here are a few proven drills:
- High-Cadence Spin-Ups: Pedal at 110–120 RPM for 30 seconds, rest, then repeat. Builds leg speed.
- Low-Cadence Power Sets: Ride at 50–60 RPM on a moderate hill to strengthen leg muscles.
- Cadence Intervals: Alternate between 90 RPM and 100+ RPM every few minutes to train adaptability.
Over weeks, these drills help you become comfortable across different cadences, preparing you for any terrain.
Average Cycling Cadence for Beginners
For new cyclists, it’s natural to pedal at a lower cadence (60–75 RPM). It feels easier at first because you’re relying on raw strength rather than cardiovascular fitness.
However, as you build experience, shifting towards 80–90 RPM often makes rides smoother and less tiring. This range is considered the average cycling cadence for beginners transitioning to intermediate riders.
Pro tip: Use a cadence sensor or a smart cycling app to track progress. Small adjustments in rhythm can lead to major improvements in endurance.
Cadence vs Speed in Cycling: Clearing the Confusion
Many cyclists confuse cadence vs speed in cycling. While they’re related, they’re not the same.
- Cadence = pedal revolutions per minute
- Speed = how fast the bike is moving on the road
For example, you could pedal at 90 RPM in a low gear and only move at 12 mph, or at the same cadence in a high gear and hit 22 mph. The difference lies in gear selection and resistance.
Efficient riders learn how to balance cadence and gear choice, using higher RPMs for endurance and lower RPMs for raw power on climbs.
Efficient Cycling Pedaling Rate: The Science
An efficient cycling pedaling rate conserves energy by shifting workload from your muscles to your aerobic system.
Research shows that a cadence of 85–95 RPM is typically more efficient for trained cyclists, while lower cadences strain the muscles more. High cadences, on the other hand, may increase heart rate but reduce muscle fatigue.
Efficiency isn’t just about energy—it’s also about injury prevention. Consistently pedaling at too low a cadence increases knee stress, while too high a cadence can waste energy.
Cycling Power and Cadence Relationship
The cycling power and cadence relationship is critical for performance. Power (measured in watts) is a product of torque and cadence.
- Low cadence + high torque = muscular strength workout
- High cadence + low torque = cardiovascular workout
Pro riders often adjust cadence depending on the situation. For example, during a sprint, they might spin at 110–120 RPM to maximize power output. On long climbs, they often prefer 80–90 RPM to avoid muscle fatigue.
Understanding this balance can help you fine-tune training sessions and race strategy.
Cadence Drills for Cyclists
Here are some cadence drills for cyclists to improve rhythm, power, and endurance:
- Single-Leg Pedaling – Alternate pedaling with one leg clipped in to smooth out your stroke.
- Fast Pedal Sessions – 1-minute bursts at 110–120 RPM, repeat for 6–8 sets.
- Climbing Cadence Drill – Ride uphill at 60 RPM for strength, then spin at 90 RPM on the flat.
- Endurance Cadence Blocks – Maintain 85–90 RPM for long steady efforts.
These drills train muscle memory and efficiency, making you adaptable across terrains.
Cycling Cadence Tips Every Rider Should Know
- Use a cadence sensor: Data removes guesswork.
- Match cadence to terrain: Lower on climbs, higher on flats.
- Stay relaxed: Tension wastes energy—keep shoulders and arms loose.
- Listen to your body: Heart rate and fatigue levels matter more than a single “perfect” number.
- Mix it up: Varying cadence in training prepares you for real-world conditions.
Improving Cycling Endurance Through Cadence
Cadence is a powerful tool for improving cycling endurance. By pedaling at a slightly higher cadence, you shift strain from muscles to your cardiovascular system, allowing longer rides without hitting the wall.
Endurance athletes often aim for 85–95 RPM on flats and 75–85 RPM on climbs. This range keeps muscles fresh while letting the aerobic system do the heavy lifting.
Combined with proper nutrition and pacing, cadence adjustments can add hours to your ride capacity.
Real-Life Example: Cadence in Action
Take Michael, a weekend cyclist who struggled on 50-mile rides. His natural cadence was around 65 RPM, which left his legs fried after a few hours.
After three months of bike cadence training, he raised his average to 85 RPM. His comment?
“It felt weird at first, like I was pedaling too fast. But once I adjusted, I could ride longer, recover quicker, and even climb better.”
This story reflects what many cyclists discover—cadence isn’t just a number, it’s a performance multiplier.
FAQs
What is the best cadence for cycling long distance?
For endurance rides, aim for 85–95 RPM on flats and 75–85 RPM on climbs. This balances efficiency and muscle preservation.
How do I improve my cycling cadence efficiently?
Use structured drills like spin-ups and intervals, track with a cadence sensor, and gradually increase cadence over weeks.
Is higher cadence better than lower cadence in cycling?
Not always. High cadence reduces muscular fatigue but raises heart rate, while low cadence builds strength but tires the legs. The best approach is balance.
What cadence do professional cyclists ride at?
Pros typically ride between 85–100 RPM, with sprints going as high as 110–120 RPM depending on the event.
Conclusion
The debate over cycling best cadence will never end—but here’s the takeaway: there’s no single magic number. Instead, it’s about discovering your ideal pedaling rhythm through practice, data, and body awareness.
By training with cadence in mind, you’ll improve efficiency, endurance, and power—all while protecting your joints and muscles. Whether you’re a beginner learning the ropes or a pro chasing watts, cadence is the silent force shaping your performance.
