One of the reasons we often see some of the best climbers in the world come from South America and Europe is often due to the hilly terrain. Due to these hilly terrains, riders like Egan Bernal and Tadej Pogacar have spent their lives learning techniques to simplify climbing. However, the road bike also played a massive role.
Are Road Bikes Easier To Ride Uphill? The road bike often features a lighter design, and the aerodynamic proficiency of these bikes makes them go much faster than traditional bikes. The combination of these features has made them much better at going uphill. However, they are not designed for mountain biking trails.
To understand why road bikes are impressive for uphill riding, we should look at the characteristics of these bikes. This article aims to help you understand what road bike brings to the table.
Now you can see why riding on uphill tarmac roads seems so easy when you are using a road bike.
If you are wondering whether Road Bikes are Worth It or not, I wrote a whole article discussing the top 8 Road Bike Pros And Cons.
Why Is The Road Bike Better At Going Uphill?
To help you understand the benefits of the road bike, we have broken down some of the main features. The following features should give you an indication of what is brought to the table by these bikes.
Remember that road bikes are some of the most expensive on the market today due to their impressive tech features.
1- Lightweight Construction
While the Union Cycliste Internationale (UCI) restricts the minimum weight of road bikes to 6.8kgs, this is still much lighter when compared to similar mountain bikes (Source: cyclist.co.uk).
Even when carbon fiber makes up the mountain bike’s frame, it could still be close to 12kgs. Some of the lightest road bikes are around 5.4kgs, which makes them very lightweight.
Keep in mind that not all road bikes are this light, and the idea is to use a carbon fiber frame to reduce the additional weight brought by aluminum and steel.
The downside to using carbon fiber lies in the price. The best lightweight road bikes tend to be some of the most expensive options on the market.
2- Lack Of A Suspension
If you buy a mountain bike, you often need to choose between the hardtail and full-suspension mountain bikes. These bikes have to overcome various obstacles and daring terrains when they are used.
Many people would choose the hardtail bike for climbing due to a single suspension, which would reduce the drag.
On the other hand, the road bike does not need suspension. This is also the reason why riding over cobblestones can be so frustrating and painful for many riders.
Keep in mind that you can find a road bike with suspension, and some of the modern road bikes will have suspension lockouts, which keep the bike stiff.
3- The Groupset Is Different
While you might think all drivetrains are the same when looking at bikes, you should keep in mind that the ratios are often different for these bikes.
Mountain bikes tend to have much lower gearing than road bikes, which makes them harder to pedal. Road bikes will have a higher spectrum of gears to improve climbing.
The groupset offers you a bigger variety of gears, with some having as many as 34 teeth on a 34-tooth cassette, and the chainset also tends to be more compact.
The more compact chainset would lead to a lighter chainset, which works with the other components to keep the bike’s overall weight much lower.

4- Bike Responsiveness
To understand why the road bike is far more responsive than any other bike on the market today, we should look at the different materials again. The best road bikes feature carbon fiber for the frame and fork. Some of the lesser models would include the aluminum frame, which is also kind of lightweight.
Due to the lighter weight, we have to look at the effect of gravity, and road bikes tend to transit power much better.
This means that each pedal stroke would affect the bike’s performance. If you are pedaling faster, you would notice that the bike moves faster, even when going uphill. Keep in mind that your custom gearing ratios also affect this.
5- Slim And Skinny Tires
Another valuable feature that makes road bikes easier to climb would be the design of the tires. Compared to mountain bikes, the tires tend to be smaller than 1/3 of the size of the mountain bike.
Having larger tires not only adds more weight, but with more surface area, you have more friction that requires more power when pedaling.
Essentially, you can do the same cadence on your road bike, and due to the lower friction and smaller tires, your bike would go much faster and be much more efficient when it comes to climbing uphill. You will find that the frames of the tires used for road bikes are also made from lightweight carbon fiber or aluminum.
6- Lack Of Road Obstacles
One reason many people skip over is the road itself. The main comparison is often between the mountain bike and the road bike, with many people wondering why the mountain bike cannot do the same. Yes, the mountain bike climbs better on rugged terrains, but you must remember that off-road tracks have numerous obstacles.
Driving on pure tarmac might have one or two potholes. However, these obstacles only make up a small percentage of the road, and they can easily be avoided by a skillful rider.
Since the rider does not need to deal with the additional obstacles, they can simply look forward and continue pedaling to ensure the bike performs.
7- Aerodynamic Efficiency/ Geometry
The geometry of the bike can easily be overlooked by many people. However, the geometry of road bikes tends to be much different than the geometry of mountain bikes. These bikes are not designed for comfort and have a much lower riding position. The idea is to break through the air with less resistance.
If you are riding uphill, the gradient would certainly matter, and it is tested that at around 25 KPH, the aerodynamic effect would be important to keep in mind. This means that higher gradients might not have such an aerodynamic effect. However, lower and shallow gradients would certainly affect the speed at which the road bike goes uphill.
How Much Faster Is A Road Bike Than A Mountain Bike Going Uphill?
One common question that people want to know about often involves comparing the road bike to the mountain bike when riding uphill. The road bike is faster from what I have seen, and some would estimate the differences to be around 30% in the best cases. However, beginners might only expect to see a 10% improvement.
Bear in mind that we also need to look at different situations. If you take a road bike off-road, you will have so much damage, and the tires might not last for going over some of these obstacles. However, cyclocross bikes have proven that you can use road bike tires on muddy terrains. Keep in mind that these tires tend to be very expensive.

Do You Consume Less Energy On A Road Bike?
If you look at many internet forums, many casual cyclists would suggest that energy consumption is similar for road and mountain bikes. However, professional riders would share a different point of view, suggesting that it is easier to pedal these bikes due to the differences in the chainrings and the cassettes.
From my personal experience, the energy consumption on a road bike feels less due to the broader spectrum of gears. Even while pedaling at a lower cadence, I feel like the road bike tends to propel me forward more efficiently.
Since you are putting less effort into pedaling and the combination of the above-mentioned features, it is proof that going uphill on a road bike would be done with less energy than on a mountain bike.
We should keep in mind that mountain bikes also tend to have more obstacles, and the rider often needs to figure out how they will overcome these obstacles, which could slow them down.
Wrapping Up
If we compared road bikes to almost any bike, we would find that they are much easier and faster to ride uphill.
It can take some time to figure out the tips and tricks which allow them to go faster. However, you would certainly notice a reduction in energy consumption.
