Let's be clear: we're talking about bikes designed for racing here. This means low ram handlebars, a long top tube of the frame and an elongated riding position with a flat back. Combined with typical racing bike geometry - a 73-74° seat angle, short chainstays - these are bikes that feel fast, have quick but predictable steering response, and are comfortable all day long if you're fit enough, to stay in the saddle for that long.
Here I will talk about the ride and handling. Other characteristics on any elite racing bike vary. Not everyone manages to stay in the position of leaning towards the handlebars due to the long stem; due to the low handlebars, the cyclist leans all his weight on front wheel, which provides good grip and control.
A good road bike must have a high-quality gear system - 53/39 front chainrings and a rear cassette with 11-23 chainrings. However, there is nothing wrong with using a compact 50/34 or larger chainring wide range. Even some professionals use such parts, and the kit latest version Shimano pro-grade Dura-Ace includes an 11-30 cassette.
However, some things are vital. Racing bikes either have very light wheels or, better yet, aerodynamic rims. Lightweight wheels add a bit of speed on a mountain road, simply due to the overall light weight, but aero wheels always add speed, which significantly outweighs their disadvantage excess weight.
A light and stiff frame is also a must, so it could be aluminum, carbon fiber, titanium or one of the steel alloys like Reynolds 931 or Columbus Spirit. If weight is a concern to you - and if you're considering buying a racing bike, it probably is - then carbon fiber should be your choice because... even the best metal frames are a couple hundred grams heavier. But metals still have their merits. For very tall cyclists, an aluminum frame may be suitable - stiff but still lightweight - and the performance of steel and titanium also has many fans.
Typically racing bikes use clamps. rim brakes, but now there are other options. Shimano's Direct Mount brakes are pincer brakes with a tighter setup that are usually tucked under the chainstays for a cleaner look.
But in recent years, breakthroughs in braking systems have been disc brakes. If you're going to be doing mainstream racing, you'll want to stick with rim brakes, but outside of racing you can really benefit from discs, which provide better braking while still saving the rims.
What are racing bikes suitable for?
In short: for fast driving. Including racing, of course, but to enjoy a racing bike, you don't have to race, you can simply add the whistling speed of a fast-moving bike to the sounds of nature.
These bikes are suitable for any type of trip where speed is important, especially if you need to cover a fair distance. Carrying options are mostly limited to a backpack, but if you're careful in your selection, you'll be able to find a bike that will pull 25mm tires and the low-profile fenders of Crud Road Racers or SKS Raceblade Longs, so you'll at least keep your butt dry, as well as You'll be able to spend a few minutes longer in bed.
And if we talk about trips for several days? With the right bags and maybe some changes to the chainring to compensate for the extra weight, you can be a great cyclist. However, racing bikes almost never come with rack mounts, and it can be said that it is not a good idea to try to make one yourself on a lightweight frame. Then you'll be putting weight on it that it wasn't designed for, and the short chainstays on a road bike will prevent you from pedaling if you attach a rack with any cargo to the frame.
During events such as the transcontinental race, cyclists carry minimal luggage, sometimes adding only a frame or handlebar bag. This is very convenient if you are staying in a hotel or sleeping on a bus, and placing the bag in line with your body does not greatly affect the aerodynamics.
Five great racing bikes
The choice is huge, as is the variety of prices. To get a little understanding of what it costs, below is an example of five excellent bicycles, the price of which is more reminiscent of car prices.
B’Twin Ultra 700 AF – 900 €
More often than not, when we review the characteristics of bikes, we highlight areas that need improvement or where they would be useful, but this is not the case with the B"Twin's Ultra 700 AF. This is one of best options for this money in terms of price-quality ratio.
We don't mean to say that there's nothing to improve on the Ultra. With a rigid triple aluminum frame, it's easy to fit some bling without overshadowing the main components.
In this case, with regard to the Ultra, it cannot be said that the price is not justified. It's not easy to find a Shimano 105 11-speed bike at this price, and even though the B"Twin has trimmed the cost slightly with the RS500 compact (50/34) gearing, it's still a very special bike. Shifting is a little less crisp without the 105 series of 5800 chains, but you'll hardly notice it.
Specialized Tarmac Sport – €1,345
We loved this bike's Ultegra-equipped big brother. However, the younger one is very attractive and well equipped and offers a very fast and exciting ride, which is quite suitable for novice riders.
Like the previous generation of Tarmacs, it's easy to live with. There are no surprises in the handling, it is very predictable and fits very easily into your home decor. This is a bike that can be used both for a whole day's ride in complete comfort and for diving into winding and narrow chains of forest paths; for commuting and work travel; and finally, for a stroll on a lazy Sunday morning to a coffee shop. Ride and relax!
Boardman Road Pro Carbon SLR – €2,160
If you want to achieve good results Whether you want to show it off on Strava or just want a fast, comfortable, easy ride, the Boardman Road Pro Carbon SLR should be at the top of your list. With features like a full carbon frameset, SRAM Force components, Mavic Ksyrium wheels and a weight of just 7kg, the SLR is a real contender, even given the price - and it can challenge even direct sales specialists.
The Road Pro is worth a closer look. Silver paint with a mirror effect makes it stand out from others, especially in the sun; you will definitely be noticed.
However, beauty is not only about appearance. In a tough cycling world where bikes start to go through all sorts of rough patches, Boardman knows exactly what it's all about, and a good racing bike is just begging for the ability to overcome challenges. He enjoys both driving on asphalt, going down a hill along the very edge of a narrow path, and competing for speed uphill.
Cannondale CAAD12 Disc Dura-Ace – €2,550
There are few brands that are as synonymous with aluminum as Cannondale, with its legendary CAAD series - "Cannondale advanced aluminum design". The American company has made a name for itself with aluminum frames, and although they have invested heavily in carbon fiber in recent years, their dedication to aluminum remains at a level that few have maintained.
The new CAAD12 is a very polished bike with a level of comfort that will make you wonder why you would buy anything else at all and, of course, why aluminum was a popular material for such a short time, only during the development of advanced technology in racing bikes in the 90s. It's so light it dwarfs many of the carbon road bikes we've tested over the years. This is nothing short of a miracle.
The Shimano Dura-Ace shifting system and hydraulic disc brakes are the expensive icing on a wonderful cake. The brakes give a feeling of solidity and enormous power, even with just one finger on the brake lever, and the subtle modulation ensures that the wheel does not lock up. The star system is just a song; When mechanical shifting is so easy to use, you wonder why you wanted an electronic Di2.
Trek Madone 9.9 – 10,200 €
The Trek Madone 9 series characterizes the latest technology The ride feels fast and comfortable, but as is often the case with innovative engineering, nothing good comes cheap. However, this bike is exceptional.
In short, the Madone 9 is an aerodynamic race bike that delivers comfort thanks to Trek's IsoSpeed decoupling, which significantly smoothes out bumps and buffeting. The effect is subtle but very noticeable.
The combination of IsoSpeed and aerodynamic frame profiles gives the Madone 9 a funky feeling of soft seating and super-speed. He picks up speed quickly and holds it beautifully.
The climbs on this bike are wonderful. It's punchy on short, steep climbs, nimble when you lift off the saddle, and feels comfortable when you keep your hands on the Madone XXX's handlebars for a long ride.

This bike was first shown at the Critérium du Dauphiné - a French road race where new bikes are often tested before being released into the Tour de France arena. The bicycle weighs only 640 grams (with a frame size of 56 centimeters) and is the lightest among all the manufacturer’s models.
Trek plans to put this miracle into mass production. Thus, Emonda can become the world's first lightest production road bike. Weight with all components - 4.65 kilograms.
Note: only bikes weighing 6.8 kilograms or more can take part in the Tour. So engineers still have room to roam.
Canyon Aeroad CF SLX
This bike is perhaps the best balance between weight and aerodynamics, which play a decisive role in road cycling. All thanks to the wind tunnels that make up the frame of this time trial horse from Canyon.

Specialized S-Works McLaren Tarmac
The new S-Works first appeared before the start of the Giro d'Italia (the Italian analogue of the French Tour). And its McLaren modification was presented a few days before the start of the Tour de France 2014. The peculiarity of the latter is that it is made of a special carbon fiber alloy. This bike frame is 10% lighter than the standard one. Another “strong point” is a limited edition: only 250 bikes are all hand-painted and have custom:
- EE Cycleworks brakes;
- Roval CLX40R wheelset;
- Shimano Dura-Ace Di2 equipment.

Merida Reacto KOM
The Taiwanese company Merida, specializing in the production of bicycles, also tried to combine successful aerodynamics and light weight. The result is a bike that is fully equipped (including Shimano mounted Dura-Ace and Fulcrum Racing Speed XLR wheelset) gained 6.8 kilograms.
Today there are only 3 such bicycles. One of them belongs to Rui Costa - a Portuguese professional cyclist, 3-time winner of the Tour of Switzerland, winner of 3 stages of the Tour de France, world champion in the group race (not to be confused with Rui Costa - a former Portuguese football player) .

Pinarello Dogma F8
The development of this road marvel was carried out in collaboration between Pinarello and Jaguar. The result is a road bike that:
“12% stiffer, 16% more balanced, and 42% more aerodynamic. And we saved 120 grams in weight,” say engineers from Pinarello, an Italian sports bike manufacturer.
The fate of Jaguar is also far from the last: British automakers conducted an aerodynamic examination of the frame in a special wind tunnel.
How are racing bikes different from regular ones? The professional racing bike combines the best features of a supremely comfortable bike for disciplines such as road racing, triathlon, track competition and cyclocross. These include the following characteristics: good inertia, low weight, aerodynamics, specific athlete's position to achieve the greatest pedaling efficiency.
Types of racing bikes
All racing bikes for roads do not have shock absorption, because it sways when riding and dampens vibrations. They also have narrow and big wheels size 700c. The front wheel is most often spoked radially. This type of knitting needle is not used on rear wheel, as it may not support the athlete’s weight. We will consider the remaining features below.
Highway
These bikes are used for riding on smooth roads. Unlike some types of city road bikes (fixed bikes), they have a freewheel and a multi-speed transmission.
Road racing is a very dynamic sport. Cyclists on road racing bikes reach incredible speeds. These bikes are never fitted with disc brakes. This is explained by the fact that if you fall, you can seriously injure yourself and others with the brake disc.
Lightness is the main attribute of a racing bike. That's why the best racers ride on high-quality carbon frames and top-of-the-line body kits. For greater stability and aerodynamics, the frame is lengthened.
The “ram” steering wheel allows you to change your position right while driving: you can grab the steering wheel from above, and after gaining speed, grab the lower part of the steering wheel
How to increase the efficiency of a cyclist's pedaling? To do this, install . They are needed to secure your foot to the pedal, due to which you can not only press on the pedal from above, but also pull it from below with your other foot. As a result, two legs will work simultaneously, and not alternately.
Previously, this function was performed by toe clips - special straps that hold the leg. They are cheaper than contacts, but hold the foot much worse. Toe clips are also more difficult to “unfasten” in case of an unforeseen situation. Their positive feature is that there is no need to buy special shoes. Clipless pedals require shoes with cleats.
Excellent aerodynamics are provided by the special geometry of the bike, narrow wheels and “ram” handlebars. The athlete stretches along the long frame and creates minimal wind resistance. The wheels are usually 28-inch tubular, very rolling. They do not have an aggressive tread as they are designed for smooth roads. The tires only have drainage grooves.
Sometimes carbon fiber rims are installed on a road bike. This makes the bike even lighter and creates even less wind resistance.
A common occurrence for road bikes is the presence of a mount for a bottle (or even more than one) and a pump, but there is no possibility of adding a rack. On a speed competition bike, the ability to carry cargo is of no use.
These bicycles are highly specialized, because you can’t ride them on dirt, you can’t jump off a curb, and so on. A road bike is needed for fast riding only on paved roads.
Cyclocross (CX)
The frame of such a bike is more durable than a road bike. It is not suitable for asphalt, but for natural forest paths. The frame is designed slightly differently from a road bike. Firstly, the saddle position is not as high above the handlebars as on a road racing bike. The landing is completely different, because here you no longer just have to rush forward rapidly, but also think through the trajectory of movement in order to successfully pass all the natural obstacles along the way. A sports cyclocross bike is designed for the fact that the cyclist will have to carry it on himself from time to time: go through sticky mud, water, etc. This bike is comfortable to put on your shoulder.
Cyclocross can be considered a hybrid of road and mountain bike
Off-road also requires more grippy brakes and studded tires. Therefore, CX bikes are equipped with hydraulic calipers with brake discs. The tires are wider than road bikes and also have the tread of mountain bikes. Thanks to these tires, you can ride a cyclocross bike in winter.
The CX bike can be equipped with a rack and bottle holders, so the bike can be used as a touring bike.
The ground clearance is increased so as not to touch the ground with the carriage, especially when turning.
Gear ratio designed in such a way that you can drive in lower gears. Obviously, you won't get as fast off-road as you would on the highway, so the chainring on a cyclocross bike is slightly smaller than on a road bike.
Cables and hydraulic lines are located above the top tube of the frame, dirt and moisture do not clog in them, so the brakes and transmission work well even in harsh conditions.
Most often used in CX contact pedals for MTB (mountain cycling). They are less reliable, but they are easier to quilt.
In general, a cyclocross bike is perfect for a person who wants everything at once. It is good to ride both on roads and on dirt, as well as go on long bike rides and participate in competitions. You can ride it at any time of the year.
Track
A track bike is not designed for anything other than riding on a special track. Bicycle hubs are designed to prevent free play. Spin the pedals and the bike moves; stop pedaling and it slows down. This is why track bikes don’t have brakes, because you can brake with pedals.
From track bikes to fixed-gear city bikes.
The wheels are made lighter by installing high profile rims or installing carbon wheels. They are very good indoors, but dangerous outdoors: the discs have excessive windage, and the wind can blow the bike sideways. The consequences for the athlete can be fatal. On a closed track, the rims perform excellently: they not only make the bike lighter, but also give the bike good aerodynamics.
There are track bikes for racing:
- sprint,
- tempo,
- leadership.
Sprint and tempo bikes are practically the same. Only the wheelbase lengths, landing and some other characteristics of the frame geometry are slightly different.
Leader bikes are significantly different from other track bikes. Chasing the leader involves riding a special bicycle behind a motorcycle, increasing speed and braking when necessary. The leader bike looks rather strange: the fork is bent back, not forward, like all other bikes, and the front wheel is smaller.
At the back of the motorcycle there is a motion limiter, indicating the area of the “air bag” in which the cyclist needs to ride
The aerodynamic properties of the bike are very important here, because if anything goes wrong, the bike will leave the zone where there is no headwind, and this can affect the outcome of the race. A professional trail bike cannot be used in the city or even in other track cycling disciplines. This bike is so highly specialized!
Bicycles for the Tour de France
The most popular road race in the world is the Tour de France. She gathers thousands of fans from all over the world. This race was first held in 1903 and has been attracting athletes who want to take part in such a large-scale event for more than a hundred years.
Competitors amaze spectators with their amazingly cool bikes. Let's look at some of them.
Scott Addict R2 TT: Scott Plasma 3
This bike features a frame-integrated seatpost, extra pads for comfort on long rides, and carbon rims.
The rear brake mount is located on the chainstay. The best solution was to install the most high-tech equipment from Shimano, including transmission, brakes, and rim. The Shimano Dura-Ace Di2 electronic system shifts gears smoothly and precisely.
Tubular tires from the equally famous manufacturer Continental fit perfectly into the image of the bike.
This bike is not the pinnacle of engineering, but it deserves admiring glances. It is equipped with linkages from Sram, FSA, Lightweight, Continental. Sram Red is a professional shift quality. Carbon parts - handlebars and high-profile rims - make this bike ultra-light.
It is used by athletes from the Milram team.
The weight of this frame from Lapierre is only 850 g. Including a rigid Easton EC90 carbon fork, innovative Shimano Dura-Ace Di2 transmission, Ritchey stem and handlebars and other bicycle components, the bike weighs 6.5 kg.
Look 595 Origin and 595 Ultra
Look is a leading manufacturer of road bikes. The Campagnolo Super Record 2x11 chainring allows for smooth acceleration without hurting your knees. Zipp rims, the front wheel is radially spoked, which improves not only the ride quality of the bike, but also appearance.
The white wrap looks great on the Full Speed Ahead steering wheel. The Fi"zi:k saddle is designed specifically for marathons such as the Tour de France.
Pinarello is pure Italian. This is a unique frame with a reduced wheelbase, which results in a slightly curved seat tube. The bicycle is equipped with sun loungers. Campagnolo Super Record 11 produced all the drivetrain and brake components for this bike. The wheels are made from Easton and Continental.
A professional bike is always a specialized bike that cannot be used for other purposes and in other conditions. If you are not going to work hard at cycling and prepare for competitions, then you don’t need an expensive racing bike. It’s better to buy yourself a more versatile bike for the city and not too extreme off-road riding.
Indeed, such bicycles exist. Whether they are called road or racing, they are designed for fast driving on roads with good asphalt surfaces. How to distinguish such a bicycle from its other brothers? Road bikes characterized by a low rider position, lightweight body, steering wheel bent downwards, narrow smooth and a large set of gears. At the same time, these bicycles are poorly suited for other roads, are not at all suitable for tourism and are very inconvenient for recreational riding.
By the way, a track bike, like a racing bike, is also a type of road bike. It is only used for sports racing on the track and usually, unlike a racing car, does not have brakes. By the way, a racing bicycle also does not have a brake on the rear wheel, only on the front, and you need to brake with the front brake very carefully so as not to somersault over the handlebars. How to make cycling more comfortable and safe in
