ABSTRACT:
This invention is a remotely actuated release clamp for a bicycle saddle post, conveniently operated by a lever adjacent to a handlebar grip. When released, the saddle may be conveniently raised by a spring lifter, and lowered by the rider's weight. The unit is lightweight, simple, grips the saddle post firmly and is operable by a small thumb lever at the handlebar grip.
No release of the rider's handlebar grip or contortions or shift of the riders body weight is required, hence the saddle height change can be safely made at high speed or without stopping his pedaling.
