Sizing your road bike and selecting the perfect model can be a tricky process due to the fact that all road bikes do not fit the same. You need to bear in mind that though two bike companies may list the same model bikes, there may be a huge difference in the measurements of the bikes. Therefore, it is very important that you know that not because you have a specific bike sizing from one company, does not mean that you are going to get the same bike sizing from another. Here is a bike size guide that will offer you information that you should know about proper road bike fitting.

Generally, when the frame size of a road bike is listed by a bike company, it tends to be some variation of the seat tube’s length. All the measurements will start at the bottom bracket’s center, and it will extend to various points of the seat tube. These points may be the top of the seat tube, the top tube’s top, the top tube’s center, and even a virtual point that you are unable to see on the road bike’s frame. If sloping tubes are added to this equation, then choosing the proper bike fitting becomes even more complicated.

In order to properly compare the frames’ sizes, you need to have a look at the head tube length and the length of the effective top tube. By doing this, you will be able to get an idea of the height and the reach that you can put the bar. An important thing to know about road bike sizing is that once you are able to stand above the top tube and having your feet flat, then you should have sufficient crotch clearance so that the stack height and the reach are comfortable for you.

Road bike bars do not have rise; therefore, in order for you to get the proper bike fitting, you need to ensure that the combination of a fork and given frame will enable you to place the bar high enough for the height of your seat.  You may use stems that have a certain amount of rise; per contra, you need to bear in mind that there are just a few choices with a rise of more than seventeen degrees, especially for the oversized handlebars that are quite popular today.

If you are shopping for a new road bike and are trying to determine your proper road bike fitting, it is best that you locate a bike shop that will be willing to take your measurements, so that you will be able to determine the stack height and reach that you need.
