It’s important to firstly measure your inside leg. If you fit in two size brackets, choose the size that also matches your height.

How to measure

Inside leg:
  • The rider should stand with their back to a wall in socks, ensuring the feet are flat on the floor.
  • Place a book between their legs.
  • Slide the book up the wall until it contacts the crotch firmly.
  • Mark the wall at that point.
  • Measure from the mark straight down to the floor.
  • Place the book flat on their head.
  • Mark where the bottom of the book touches the wall and measure straight down to the floor.
