Bike sizing

Here is a little help for people who do not know what size they should ride. In general this can be used, but we would advise you always to do a professional bikefit. Note that sloping frames and mountainbikes have different sizes, check those sizings with the manufacturer.

A few things need to be measured to get your size. On our website we mention 2 sizes (seat tube & top tube) using the picture above:

The length of the seat tube, which is called c-t in cycling terms.
To get this size you need to :

• Stand straight, back against a wall
• Stand with your feet hip width apart (shoes off), place a spirit level between your legs
  
• Have a helper measure the distance from the top of the spirit level (where your crotch is) to the floor

This now tells you the inseam measurement for the c-t. See picture below

The length of the top tube, which is called t-t in cycling terms.
To get this size you need to :

• Measure the length of your torso and your arms and add these two numbers together
• Divide that number by two and subtract six. This will give you the top tube length in inches
• Measuring in inches. To convert this to centimetres, multiply the result by 2.54

Now you have these measurements you can use the following size chart to find your seat tube (c-t) size. Check the top tube (t-t) size at the bike`s specifications that should not differ too much from what you measured.
