Flaps can be rotated by the rider forward or backwards by 3cm by changing the position of the flap fixing bolts. This is a significant amount as there is only 5cm difference between a Dressage and a Jumping Flap.
When ordering your saddle’s flaps you choose which 2 angles from 4 are best for you and your position i.e. red & blue, blue & flap as shown or flap as shown & green.
This means that different riders can share the same saddle even if they have different leg lengths or positions.
