This is because manufacturers now produce compact sloping frame designs with lower top tubes. That means somebody who fitted a 56cm frame in the s will probably need a different size now.

Simply put, your stand-over height is the distance between the top tube and the ground. This can have a major bearing on your overall comfort levels and your performance. For the optimum size, there should be a few inches between your crotch and the top tube when you are standing barefoot with your legs straight and feet slightly apart.
Know your inside leg measurement? This can be a good indicator of how high you need the top tube to be. Important note: You need to take the style of the frame into account. For example, a compact frame will have a lower stand-over height than a traditional horizontal geometry frame because the top tube has a clear slope. Tip — If you have a compact or semi-compact geometry frame, make sure you have enough clearance along the entire length of the top tube, especially near the head tube, as this is the highest point.
An adult cyclist should be able to touch the floor with their tip-toes while sat in the saddle. Here are a few tips to help you get your saddle in the perfect position:. Similar to some Adults, Kids can typically fit a broad variety of sizes. Understanding kids frame sizes can be difficult, thankfully the chart to the right should point you in the right direction.
A children's bike is also reasonably flexible in size. Everybody is different, so the values in our tables are only guideline values. For example, women and men differ greatly in their body proportions.
The frame sizes are the same for men's bicycles and women's bicycles. However, what clearly differs is the frame geometry. In some cases the top tube is shorter for women's bikes, in simpler terms: the distance from the saddle to the handlebar is shorter to better suit the female physiology.
Have you tried it out in person? Buying a new bike sight-unseen is a recipe for pain and a bike that won't be ridden. One very important bit of information you should add is exactly how the "size" measurement is done on the bike you are considering. Commonly, size refers to the distance measured along the line of the seat tube from the bottom bracket to a point in space where the top tube would meet the line if the top tube were horizontal. But some bikes will measure to the point where the actual sloping top tube meets the seat tube, so the "size" is much smaller for a given bike.
Thus 49 and 50 may be sizes comparable to a typical 54 or so. Add a comment. Active Oldest Votes. Some people about the same height with short legs fit a 52cm frame with a long stem fitted. Improve this answer. Argenti Apparatus Argenti Apparatus This, definitely. Can't imagine riding it as a road bike as an adult as opposed to a trick, BMX bike. Joe: 50cm frame height can easily be the right size for a cm woman. You should be able to reach them comfortably without hunching over them or stretching your arms way out.
Notice the pads on the handlebars and how they feel. Are they spongy or hard? Hard surfaces can fatigue your hands over long rides. Look at the pedals. Metal ones are more durable than plastic ones. Some higher-end road bike pedals have toe cages or toe clips. Unless you're building a bike from the ground up or buying a high-end model, you're stuck with the tires , brakes, gears, and other components that come with the bike.
That's OK, especially if you're a beginner or a casual rider. Your choices will be largely dictated by cost, but it's worth considering the components. Frames are made of aluminum, steel, titanium, and carbon fiber. Most bike frames are made of aluminum, which is lightweight and durable.
You'll find steel frames on older bikes or custom builds; steel is heavier and tougher than aluminum. Titanium and carbon fiber frames offer the best features of aluminum and steel, but they're also more expensive. Brakes do the same job they do on a car: stop you from moving.
Cheaper bikes have rim brakes, while better models have disc brakes.
