Let's mount the saddle on our unicycle

In the drawing below you find the measures of the standard seatpost fitment used for all unicycle saddles currently on the market.

There is also a different seatpost fitment usually used in low-value products made for the Asian market. If you want to change the saddle pay attention to the seatpost fitment. If it is not standard you have to change the seatpost, too. Check also the diameter of the seat tube. Usually it's 22.2 mm but it can also be 25.4 or 27.2 mm.
