Adjusting the distance between the saddle and the handle bar

It is important that the distance between the saddle and the handle bar should suit the rider.

Place the elbow at the point of the saddle and stretch out your arm and hand. The distance between the saddle and the handle bar should be approximately 5 cm. if necessary, slide the saddle forwards or backwards after loosing nuts A.

When re-tightening, make sure the saddle remains in an almost horizontal position and see that it is properly centred.

After re-tightening, ensure that the saddle is secured firmly and cannot be moved.
