- Improved riding technique
- Better equipment selection and the savings of buying the right bike/products the first time
- Peace of mind
- Enjoyment in your riding

Step 1: measure your inseam/inside leg

This is the basis for calculating the correct frame height for your next bike.

To find your measurement, stand with your back against the wall barefoot. Have your heels touching the wall and your knees straight. Using a book, flush agains the wall on one side. Measure the distance between the books upper edge and the ground. (See diagram)


Step 2: Calculating your frame height

Using your measured inseam/inside leg use this calculation to find your approximate frame size.

The result is the frame size in inches (1 inch = 2.54 cm). In a few cases, the measured size will match exactly with the one offered by the manufacturer. Thus the following applies:

1. For an athletic riding style, please select the smaller frame size.
2. For a more relaxed seating position, please select the larger frame size.


MTB Full Suspension: multiply the inseam/inside leg by 0.225.

MTB Hardtail: multiply the inseam/inside leg by 0.226.

Road and Cyclocross: multiply inseam/inside leg by 0.635.

Cross bikes: please multiply the inseam/inside leg by 0.259


Example: 79 cm x 0.225 = 17.775
Thus the optimal frame height would be about 18“/46 cm.

For this example, you would choose a 17” bike for an athletic riding style; a 19” version has a comparatively “tourier” character.
