You can determine your mountain bike size using a table chart, but we don’t recommend to use this on any other table to buy an expensive mountain bike over the internet. Some manufacturers might have their own, slightly different sizing table.


HOW TO CHOOSE THE RIGHT FRAME SIZE FOR MOUNTAIN BIKE

Choosing the correct mountain bike size can be harder than you think. Riding style, the type of mountain biking, personal discrepancies, gender, all this things can influence the correct size of your MTB. Relaxed shoulders, slightly bent elbows with the knees being slightly bent to the bottom of each of pedals stroke. This is a general rule. Having the right size does not only mean safety and more comfortable position, but you get much better performance and efficiency when you are out tackling those tricky tracks and offroads. Plus well sized bike puts less strain on the joints letting you ride longer and harder. Taking measurements is very important to determine the mountain bike size, but we wouldn’t advise you to buy a mountain bike without a test ride, and we don’t mean a lap around your local Halfors. If you buy the bike worth thousands of pounds a proper outdoor test is a must, try as many as you can and choose the right one.



SIMPLE CALCULATION FOR THE RIGHT FRAME SIZE

As much as measuring your whole inseam can be very important, it can be very tricky for people with anatomical differences, shorter or longer torso for example. For general mountain biking the most important measurement would be obtaining the size of your inside leg for the frame size. The wrong frame size and you’ll end up with back and other joints pain, lack of control or lack of stand-over clearance, Och !!! When you mount and dismount your bike you will be swinging your leg over the top tube, and you will need to ensure that you have enough clearance, minimum 6 cm (2.5 inches) clearance is recommended for mountain bike, slipping of the peddles might be particularly unpleasant for male riders. This clearance is the difference between the inside of your leg measurement and the stand over height of the bike in question. Stand over height is the height of the bike from the top of the top tube to the ground. You can determine the size of the frame either in these two simple steps or picking your size from the manufacturers chart.

1- Measure your inside leg: Stand up straight having your back against a wall and a book between your legs like the bike’s seat. Push the book up until it starts being a little bit uncomfortable and measure the distance between top of the book and the floor.
2- Calculate the right frame size: Multiply your inside leg measurement by 0.226. to get your size in inches and by 2.54, to get the frame height in cm.
