If you’re looking to buy a new road bike, you’ll need to understand how to measure the frame size before you make a selection. Choosing the right frame size for your body type and preferences is essential, and it’s always best to double-check the measurements so you get the most comfortable fit. This guide will provide you with a few easy steps to measure a road bike frame.
First, stand the road bike upright and look for the serial number. This serial number is key to finding the right frame size for your new bike. All bike frames come in specific sizes, and the serial number will identify which one you need for your height and inseam.
Once you have the serial number, you’ll need to find the frameset, or frame size in centimeters. This number grants the bike its exact size and can usually be found on the bottom bracket of the frame. Knowing the frame size in centimeters will tell you what size bike you should buy.
Now, measure the top tube of the frame. Measure the distance between the head tube and the seat tube. This measurement will help you decide which type of road bike will fit your body type. To do so, use a tape measure to find the distance of the top tube end to the center of the head tube. The distance you measure should be compared to a chart from a bike sizing calculator. Keep in mind that this measurement will vary depending on the frame type and manufacturer.
Finally, determine the reach of the frame. Reach is the distance from the bottom bracket to the center of the handlebar stem. Many bike frames have a reach that is slightly longer than the frame size – this is known as fit. If your frame has a longer reach, then it is more suitable for comfortable, long-distance rides.
Knowledge about how to measure a road bike frame is essential for anyone who is looking to purchase a new bike. The frame size, top tube length, and reach all factor into finding the perfect road bike fit. With a little bit of research, you should be able to find the bike that fits your body type and personal preferences.
