Two-point sizing system.

Our sizing system takes the guesswork out of finding the right bike size. It requires two measurements. Your height and your inner leg. Follow the steps below to take your accurate measurements.

Your height

  1. Stand with your back to a wall and place a spirit level or book on your head parallel to the floor.
  2. Measure from the floor to the book or spirit level.
  3. Make a note of your height measurement.

Your Inner leg

  1. To make things easier wear your cycling bibs or some well-fitting underwear and stand with your back to the wall.
  2. Pull the book or spirit level up between your legs as close as possible to your sit bones.
  3. Measure from the floor to the top of the book or spirit level.
  4. Make a note of your inner leg measurement.
This measurement significantly influences your frame size – please make sure to take it precisely.
