On bicycles, especially MTB (Mountain Bike) and Roadbike, often there are measurements on each frame or commonly known as sizing. This size difference aims to provide an optimal driving experience for each rider who has a different body posture. You can ask bike shop Denver if you need help.
Seattube Length or seat tube length is usually a benchmark in bicycle measurements. Seat tube length is measured from the middle BB to the top end of the seat tube (C-T / Center to Top). There are bicycle manufacturers who use the terms Small, Medium, Large, and those that use nominal sizes such as 16 “, 17.5”, 18 “. Basically, the higher the driver, the bigger the frame size will be needed.
But sometimes it is found that a bicycle is only produced in one size, for example, MTB is only produced in size M or 17 inches. Measurement of frame size also usually does not apply to folding bikes, because folding bikes tend to be set on the seat post and handle post in adjusting the user’s posture. There are several methods commonly used to determine the ideal frame size for a rider, including:
1. Factory Recommendations
This method is considered the most accurate for determining the size of the bicycle frame that should be used. Bicycle manufacturers or manufacturers certainly understand every detail of the geometry of a frame that they create. Usually, you can see the size recommendations listed on the bicycle frame or the manufacturer’s website itself.
2. The Standover Height Method
The Standover Height method is a traditional method that is widely used. The measurement is quite simple, the rider simply stands on the bicycle. Motorists simply measure the distance between the groin with the top tube or commonly called clearance. On the road bike ideally, there is a 1-inch clearance, and on the MTB there is a 2-inch clearance. This method is the simplest, easiest to implement, and is quite widely used until now.
