Top 10 Best Road Bike Sizings in 2021 Reviews


When buying a road bike, the right side of the frame is of great importance. The best road bike is useless if its size is not right. The frame height, therefore, has a strong influence on driving pleasure and comfort. Depending on the wheel type, different parameters are required to calculate the frame height. Find out in this guide which formula you can use to determine the right racing bike size.

Calculate the correct frame height of your racing bike

Once you’ve found your dream bike, all you have to do is answer one crucial question: What size should the frame be? The right frame size is more important for road bikes than for other bikes. It is the standard size according to which a suitable racing bike is normally ordered. The frame size represents the length of the seat tube measured from the center of the bottom bracket to the intersection with the horizontally measured top tube. It is best to always measure yourself using the method described here, as some manufacturers use other methods to determine the size.


Your stride, divided by your body size, will yield a factor that describes your body proportions. Reading example: At a body height of 178 cm, with a step length of 81 cm (factor 0.455), you are exactly in the middle of the spectrum. Standard frames are then a good starting point. Langbeiner chooses the frame rather comfortable, Sitzriesen sporty. Note: In the survey sheet, the body proportion factor, unlike in the graphic above, is output as a number between -5 (sitting giant) and +5 (long-legged).

How to find, based on your body proportions and the desired seating position, the appropriate frame in the test field

  • Measure step length Stand: in front of a wall, feet with pedal spacing. Press a book with your back in the crotch and measure the distance from the spine to the floor. Frame height (stack) = 0.69 x stride length (cm) Add 2 centimeters (small frames) or 4 centimeters (large frames) for a comfort geometry.
  • Divide your stride length by your height (in centimeters each): Check the chart on the left to see if you’re average, or sitting giant or long-legged. Use the following matrix to find the geometry that suits you the most among the frames with the height that suits you best (STR factor).

Your individual stride length is the most important parameter for calculating the frame height of a racing bike. The best way to calculate your stride length is to stand with your back against a wall, put a thick book between your legs (simulating the saddle) and measure the distance between the top edge of the book and the floor. Multiply your step height by a factor of 0.665 to obtain the theoretical frame height in cm. If it is a triathlon bike, you should subtract approx. 3 to 3.5 cm from the determined value. It is best to ride a racing bike of your calculated size – as well as a larger and smaller wheel for comparison – to be on the safe side

Bike Features Reviews


  • Steering angle/fork bending together determine the caster – decisive for the steering behavior. Typical: steering angle of 73 and caster of between 55 and 60 mm. The steeper the steering angle or the shorter the caster, the more nervous the steering behavior
  • Wheelbase, agile handling long, straight-ahead
  • Short chainstays mean higher load on the rear wheel
  • Bottom bracket lowering affects ground clearance and mobile crank length
  • Small frames (less than 52 cm)
    – have flat steering angles and consequently sluggish steering performance
    – benefit from small wheels that allow smoother ride and better balance
    – have (too) steep seat angles
  • Large frames (over 60 cm)
    – are comparatively short and tall
    – have relatively short wheelbases
    – tend to have flatter seat angles
    – have too little ground clearance for long cranks


Small frames tend to be more sporty than large ones, with a few exceptions. This is because large frames grow more in height than in length (meaningful would be proportional growth). Limiting factors for this are the constant wheel size and the only marginally increasing wheelbase. From this, one could conclude that smaller people are forced to a stretched sitting position and large ones to a more upright position – even though they may want to sit quite differently. But do not panic: the STR value refers only to the frame and does not take into account that there are stems in lengths of 70 to 150 millimeters, which allow a lot of leeway for the position adjustment. Incidentally, it also looks better if a small bike with a shorter stem.

  • Choosing the right seating position: The seating position strongly depends on the geometry of the road bike frame. So before you buy a racing bike, you should determine which seating position you prefer.
  • Tour Position: You are on the road for a long time. It is not so much the speed, but rather the distance. The touring position is usually upright and therefore more comfortable. Touring and long-distance racing bikes are designed for long distances. Here it is particularly important that does not hurt after an hour of the neck. Racing bikes with a long-haul geometry therefore usually have a shorter upper tube in relation to the seat tube, paired with a longer head tube.
  • Sporty position: The sporty sitting position lies between the touring and the race position. You sit road bike-typically slightly stretched, but not too extreme. Road bikes that allow this position, usually have similar length seat and upper tubes and a moderate control tube length.
  • Race Position: You also race and do not want to give a second because of an upright sitting position and suboptimal aerodynamics? Then comes for you a road bike with a longer top tube and relatively short head tube in question. The long top tube and the short head tube result in a stretched, bent and aerodynamically optimal seating position.

You must pay particular attention to the following when buying a bike

  • Tires
    With regard to driving safety, the few square centimeters of tires are of crucial importance to the driver, the tire width should be at least 26×2.25 inches. Special precautions must be taken by free riders as well as downhillers – these require a large footprint and plenty of grips. Most tires are also equipped with extra thick carcasses (= the supporting frame in the tire) and special puncture protection. The close mesh of the carcasses is given with the EPI or TPI number (threads per inch). For example, a tire with 30 EPI has low stability and is less suitable for off-road driving. The higher the EPI / TPI number, the safer the ride. If the number is around 120 EPI again, this means low rolling resistance and low weight – the carcass is extremely fine, increasing susceptibility to breakdowns (suitable for cross-country racers).
  • Rims: As standard on professional mountain bikes are considered hollow rims. For the beginner, the simple aluminum rim is sufficient at the beginning.
  • Frame: You must pay particular attention to this component of your new vehicle – popular and suggest are aluminum or carbon frame. In addition to lightness, they are also characterized by great stability, which is a significant advantage in terms of driving through the terrain. Fully are usually in four, while hardtails are available in six or even more sizes. The frame height must be based on your height orient (with a size of more than 1.85 m we recommend 28 “frames); a rough guide is the measurement of your stride length (inner leg from crotch to ground); multiply the measured value by 0.266 and you will get the theoretical frame size in inches. To sure recommend a test drive.
  • Suspension: An integrated suspension is not a must; however, the suspension fork is part of a good mountain bike. On the one hand, this contributes to the reduction of wear on rims, tires, and axle and on the other hand provides a pleasant driving experience and spares the joints of the driver. Most bicycles can also be retrofitted here.
  • Circuit: In addition to the right setting, the circuit is the most important part of the dream bike is in tests brands such as Shimano or Sachs has been proven in the past frequently -. To the circuit should not save you.
  • Brakes: Brakes are available in several variants – V-brakes, disc or hydraulic brakes. For driving safety, regular testing and maintenance are mandatory for every biker! Brake pads should be changed regularly; a worn surface is recognizable by a grooved surface. In addition, glazed or smeared brake pads pose a great risk; Nitrification is the result of hard use at high outside temperatures and is noticeable acoustically as well as the deteriorated braking performance due to loud brake noise.
  • Safety: For your own safety, you should take appropriate measures – first of all, the bicycle helmet should be mentioned (wearing reduces the risk of injury to the head by up to 75 percent!). When buying, pay attention to the exact fit and the ventilation of the head. In addition, the purchase of appropriate clothing is advisable: Bike pants, shirts, and jackets, arm, and leg warmers, cycling shoes, sunglasses, and gloves provide protection and functionality. To try it out, simple sneakers are enough for the beginning, with corresponding click pedals you can upgrade your bike later. Since you may be cycling in wind and weather, you should also have clothing that protects the rider from wind and rain, and weighs the purchase of, among other things, studded tires designed for use on snow and ice. In the trade you can buy special mountain bike equipment, the equipment differs partly in terms of the cuts and function of the normal clothing from the street sport.
  • Accessories: When purchasing the original equipment you should also purchase helpful items such as tools – breakdowns are part of the everyday life of mountain bikers. For the beginning, it is sufficient to carry a small air pump and a spare hose with him. Other useful accessories are beverage bottles, an onboard computer, a heart rate monitor or even a GPS system. Although the latter is not mandatory for the beginner, it is still possible to upgrade and buy later.
  • Price: For the purchase of a good mountain bike you should plan about 700 dollars, on the top are no limits set (the most expensive series bikes have now cracked the 10,000 euro mark). For example, a fully off-road hardtail is already around 1,000 dollars. If you invest a little money at the beginning, the driving fun can otherwise come to an abrupt end thanks to cheap drive components or weak brakes, and the retrofitting can cause a big hole in your wallet. Top brands and box office hits include GT, Scott, Kettler, Giant, and Wheeler.

Not to be forgotten are follow-up costs- especially chain, cassette, tires, and hoses, and brake pads are among the wearing parts that you have to replace now and then. With an annual mileage of 2000 km, you can roughly expect costs of around 150 dollars.
