Select a racing bike: Long Distance vs. Aero vs. Climbing the Pass


Looking at the current road bike market, you can see that manufacturers are increasingly specialized in their product lines to cater to different needs and roads. It's hard to find a multifunctional road racing bike. Instead, the current major brands mainly produce three specialized road bike branches: lightweight road bike line for conquering slopes, aero / aerodynamic racing cars road bike) to enhance speed and long distance (bike endurance road bike) to create a sense of comfort for hours of cycling sessions. However, a vehicle does not necessarily fall into one of the upper branches that will have certain crossings.

With the increasing cycle of cycling and triathlon in Vietnam, Boidapchay has spent time summing up the differences between the different road bikes with the desire that the community can find the right bike. suitable for each person's needs and budget. The following article uses the specialized terms in bicycles. For convenience, you can refer to the article about Boidapchay racing bike terms.

Long-distance bikes (sometimes called Endurance Bike, Sportive Bike)

Long-distance bikes are born to make you feel comfortable and durable. This is the first bicycle line used to conquer the stone paws of the Classics races in northern France. These are the races that crabs have to brace all day at high speed through the "hardest" roads you can think of. To minimize the muscle fatigue caused by road vibrations, long-distance bicycles are designed with flexible adjustment and larger tire clearance to allow surface tires to be used. Large horizontal and good shockproof.

The versatility of long-haul vehicles is different from manufacturer to chassis. Specialized has "Zertz", a part that attaches to the fork and rear seat stay, which helps to reduce shock better. Trek has "Isospeed", a part of the saddle that can move and change flexibly according to the road conditions to make the car feel comfortable. Bianchi does not have mechanical parts to increase flexibility, but instead "vicoelastic" materials (known as Countervail technology) are integrated into the ribs to reduce aftershocks.

Most long-distance bikes have large tire gaps to allow for wider tires. Using wide tires has a lot of benefits. Compared with narrow tires, wide tires can roll at a lower pressure, thereby reducing vibration and providing a smoother ride. In addition, wide tires also help reduce rolling friction with the road. Most road bikes are fitted with 28mm tires, in some cases up to 32mm.

Different from the aero, long-distance vehicles aim for a more upright position than leaning. The neck tube and the length between the two wheel axles are longer. The reach index is lowered (that is, the leaning from the seat to the short handlebars) while the stack index (the vertical length measured from the middle axis to the center of the neck tube) is increased. These changes aim to give the crabs a more upright, high sitting position, less parallel to the ground, thereby reducing the burden on the back, shoulders, neck and hamstring muscles.

In parallel with wide tires, increasing the length between the two axles also contributes to the stability of the vehicle. In addition, the handlebar length also helps to improve stability. Long-haul cars usually have 46cm long handlebars instead of 40-42cm of aero or mountain bike.

Long-haul vehicles are usually fitted with a compact crankset with a big trunk, which helps to push the pedal easier, and helps the foot relax during long pedaling days. The long disk drive for long-distance cars usually has the index of 50-34, while the floats are usually 11-28 or 11-32.

Aero bicycle (AERODYNAMIC ROAD BIKE)

Aero racing bikes were born to minimize friction and to glide smoothly through the winds. 85% of the drag comes from their own bodies, so bicycles are designed with short neck tubes, helping the crabs to lower themselves thereby reducing friction from the wind. In parallel with the low-necked tube, the aero has a longer reach of the rib than a long-distance bike (meaning that the athlete will sit backwards, longer to hold the handlebar, thus creating less aerodynamic posture effects of wind).

The design of the aero flanks is most easily recognized in the 3 road branches because they are quite bunk and angular. The tubular sections on the long, thick chassis and tail sections are trimmed with curves. The horizontal alignment of aero cars is usually straight and flat, compared to the slanted horizontal sections of a mountain pass or a long-distance vehicle. Because of the straight line, the car has to bend lower to touch the handlebar, resulting in a greatly reduced friction. The standing position of the aero car is also often lower to make the sitting position as low as possible. Because of the thick side tubes, aero cars are often heavier than the rest.

The integrated design is the second highlight of the aero. Sometimes aero brake mounts are hard to spot because they are often "hidden" inside the flanks. Many brands have arranged rear mounts near the middle axis, or like Trek with the unique design "Vector Wings" that go with the mount in the middle tube. The latest aero models such as Specialized Venge 2019, Cannondale System Six or BMC Time Machine Road 01 also have an integrated recording system (with potang and freezer integrated into one block) to minimize thread wires, Brake cables help eliminate unnecessary friction.

Aero models are often painted with high rim to increase aerodynamics. Aero rims are usually at least 40cm high, sometimes up to 80cm so that the car can tear the maximum wind. However, the weakness of the high rim is heavy weight, and difficult to control the car when it is windy.

Lightweight mountain bike

As the name suggests, lightweight road bike is usually very light weight. Because this car combines many characteristics of aero and long-distance vehicles, mountain-climbing cars are often a popular choice for those who want to own a versatile vehicle. They usually don't feel as comfortable as long-distance bikes, but they are still more comfortable when riding aero. In terms of compactness and toughness, the mountain bike ride is not as good as aero car but more than long distance car. The control of hill-climbing cars is more accurate and easier than long-distance and mechanical vehicles with aero cars, and may be even more agile because they are lighter than aero cars.

The frame shape of a mountain bike is usually designed to be as thin as possible, but this does not affect the rigidity and durability of the frame. The thin frame tubes help reduce vehicle weight and increase control flexibility, while reducing vibration aftershocks give you a roof-kicking experience. To get the right balance between weight and compaction, mountain bike builders often reinforce the stiffness of their pipes, shafts, collars and chainstay by using different types of carbon or try to add more layers of carbon. Although a mountain pass may not be as compact as aero, the ratio of compaction to volume is much better than aero.

There is no uniform mountain bike frame design between different brands. Many manufacturers with separate aero, downhill and long-distance models often design a rugged and angled mountain bike (like aero) because those who want to feel comfortable can choose long-distance vehicles. Meanwhile, a number of other brands design mountain climbing cars with a "more comfortable" shape because they do not have a lot of budget.

Choose the right car
The important question here is, which car to choose. The answer depends on many important factors as follows:

Purpose of Use: what do you want to buy a bike for: do excursions every weekend, explore the hills, or shorten your achievements at an upcoming tournament? If you want to buy a bike just for leisurely weekend riding, you just need to buy a long distance bike. If demand is about shortening performance, you should consider aero or a mountain pass, especially for steep roads.
Experience / Long cycle riding: sitting for 3 hours with a low crouching position on an aero bike is not easy. If your body is not tough enough, or you do not have much experience in cycling, you should choose a tough road or mountain bike instead of aero.
Budget: Most aero and downhill cars are more expensive than long-distance vehicles, so if you're looking for a car to train on, the long-haul is a more affordable option. However, if you want to shop "once and then" then BoiDap Think of mountain climbing cars is a more versatile option.
Finally, for whatever model you choose, it is extremely important to make sure you are compatible with the vehicle (fit) because it will help you train well and minimize unnecessary injuries. When buying a car, do not forget to use the fit service (bike fit) to find the most suitable sitting position possible. Wish you find the car you want and practice fun!
