Why Does My Road Bike Feels Slow

Why Does Your Road Bike Feel Slow?

It’s a common experience for cyclists to wonder why their road bike isn’t performing as efficiently as it should be. With various factors potentially contributing to a slow-moving bike, it’s crucial to identify the root cause in order to make necessary adjustments.

The reason your bike feels slow could be due to mechanical issues such as friction in the brakes, the wheel or the drivetrain, extra weight, power loss, or even unusual riding conditions.

In order to address the problem and improve your cycling experience, it’s important to understand the impact of various factors on the bike’s performance.

Keep in mind that an optimally-performing bike will not only provide greater speed but also enhance overall cycling enjoyment.

Factors that are Behind a Slow Road Bike

Here are some common culprits to consider when your road bike feels slow:

– Low tire pressure
– Poorly lubricated chain and gears
– Misaligned brake pads
– Incorrect saddle position
– Excess weight on the bike
– Challenging riding conditions, such as headwinds
– Worn bearings
– Inefficient pedaling technique [1]

#1- Low Tire Pressure: The Common Culprit

When your tire pressure is too low, it increases the rolling resistance, making your bike feel sluggish.

As mentioned in an article on Bicycling, floor pump gauges are not always accurate, which means it’s essential to invest in a separate and reliable tire pressure gauge for consistent measurements.

It is also worth noting that one should not use the same pressure for front and rear tires since your weight distribution is not even.

Remember to regularly check your tire pressure and adjust as needed to maintain your bike’s optimal performance. [2]

#2- Chain and Gears: How to Keep Them Lubricated

A well-maintained chain and gears are essential for keeping your road bike running smoothly and feeling fast.

Over time, the dirt and grease accumulate on the drivetrain, increasing pedaling resistance and making your bike feel sluggish.

To keep your chain and gears lubricated effectively, consider the following tips:

– Lubricate the chain frequently, especially if commuting daily in wet or grimy conditions. An all-weather formula, such as Pedro’s Syn Lub, works well for this purpose.

– Clean the drivetrain thoroughly a few times a year. You can use a Park Tools cleaning kit for a DIY approach or consult your local bike shop for assistance.

#3- Brake Pads: Check and Adjust Regularly

Ensuring that your brake pads are in tip-top shape can significantly impact your bike’s overall performance and consequently, your riding experience.

– Over time, brake pads can wear down, which may result in reduced braking efficiency and a sluggish ride. To avoid this, inspect your brake pads frequently for signs of wear and replace them when necessary.

– Improperly aligned brake pads can cause rubbing against the wheel rims, increasing resistance and slowing you down. Be sure to adjust the brake pads’ position to prevent unnecessary friction.

Finding the perfect amount of pressure may require some trial and error, but mastering this skill will greatly enhance your bike’s performance.

#4- Saddle Position: The Importance of Proper Adjustment

Saddle position might not be the first thing that comes to mind when considering bike speed, but it plays a crucial role in your ability to ride efficiently.

Proper saddle adjustment ensures optimal power transfer and comfort, crucial for maintaining higher speeds.

Here are a few key points to remember about the importance of proper saddle adjustment:

– Height: Adjusting the saddle height, so your leg is almost fully extended at the bottom of the pedal stroke can ensure efficient pedaling and reduce the risk of injury.

– Angle: The saddle should be level, with just a slight tilt in favor of your sit bones, providing support during long rides and proper posture for efficient power transfer.

– Fore-Aft: Proper saddle position means your kneecap should be directly over the pedal spindle when the pedal is at a 3 o’clock position, optimizing power transfer and reducing the risk of strain on your knees.

– Comfort: Make sure your saddle is comfortable and supports your sit bones well, enabling you to maintain proper riding posture and further improve the efficiency of your ride.

#5- Weight: How Carrying Too Much Affects Speed

Whether it’s extra gear, a heavier frame, or even the rider’s own body weight, every additional pound makes a difference.

Here’s how carrying too much weight affects your road bike speed:

– Increased rolling resistance: Heavier bikes require more effort to overcome rolling resistance, causing slower speeds and fatigue on the rider.

– Decreased acceleration: Extra weight affects the bike’s acceleration rate, making it harder to reach top speed or maintain momentum up inclines.

– Strain on components: Heavier loads can put unnecessary stress on bike components, leading to premature wear and potential damage.

– Energy expenditure: A heavier bike or added gear means riders will exert more energy to maintain speed, leading to quicker exhaustion and reduced performance.

#6- Riding Conditions: Headwinds & More

Headwinds are more than just a natural annoyance; they can genuinely impact your pedaling efficiency and make it feel like you are putting in double the effort to maintain your usual pace.

– When facing headwinds, adjust your riding position by lowering your upper body, which reduces air resistance.

– Riding in a group can help combat headwinds, allowing cyclists to take turns leading the group and “breaking the wind” for the others.

– Other weather factors that impact your speed are rain, snow, and temperature changes, which can affect tire pressure and your bike’s mechanical components.

– Riding uphill or navigating rough terrains can also make your bike feel slower, as it requires more effort to maintain the same speed as on flat, smooth surfaces.

#7- Worn Bearings: When to Replace

Worn wheel bearings are a major factor that can make your road bike feel slow. They usually go unnoticed and unattended, causing drag and wear on your hubs which can hamper your speed and performance.

To maintain a smooth ride and prolong the life of your wheel bearings, it’s essential to check them regularly and replace when necessary.

* A basic method of checking wheel bearings involves listening for a dull whooshing sound indicating that they’re dry. If you feel any vibrations while spinning the wheel, it may be time to inspect the bearings.

* Degraded grease or worn bearings can create resistance and require a replacement. Visual inspections can help determine if there’s enough grease and if the condition of the bearing is satisfactory.

* Replacing worn wheel bearings also prevents more expensive issues, such as a wheel write-off, ensuring that you maintain optimal speed and performance on your road bike. [3]

#8- Inefficient Pedaling: Work on Your Technique

A smooth and consistent pedal technique ensures maximum power transfer and minimizes energy loss, allowing you to maintain a higher average speed. Improving your pedaling technique can be achieved in various ways:

– Practice pedaling in circles: Focus on applying even pressure throughout the entire pedal stroke, avoid stomping or pushing down only in one part of the stroke.

– Utilize clipless pedals: These pedals allow you to engage more muscles during the pedal stroke, leading to a more efficient pedaling technique.

– Work on your cadence: Aim for a steady cadence of 80-100 revolutions per minute (rpm), which has been found to be the most efficient range for most cyclists.

– Incorporate single-leg drills: Practicing single-leg pedaling can help identify and correct any imbalances or inconsistencies in your pedaling technique.


Reclaiming the speed of your road bike is possible by addressing some common culprits and improving your riding technique. Here are some key takeaways to get your speed back up:

– Keep your tire pressure at the optimal level to reduce rolling resistance.
– Regularly clean and lubricate your chain and gears to maintain smooth performance.
– Adjust your brake pads to prevent rubbing and slow-downs.
– Ensure your saddle position is properly adjusted for efficient power transfer.
– Be mindful of carrying excess weight that can affect your speed.
– Consider riding conditions such as headwinds which can impact your perceived speed.
– Replace worn bearings to reduce friction.
– Work on improving your pedaling technique to increase efficiency.
