Fore / Aft Adjustment
The fore / aft adjustment is the distance of the tip of the nose of the saddle in
relation to the bottom bracket axle. Usually this is behind the bottom bracket axle
- around 5 cm. The taller the person is, the further behind this line the tip of the
saddle will be - up to 10 cm. For a shorter rider this distance may be reduced to
0 - 1 cm.
