|1. When the crank arm rotating from 12 o'clock position to 3 o'clock position.
|When a person walks, the upper and lower body move forward simultaneously. So the pedalling is moving just like walking. When the foot position falls, the posiong of the hipbone moves from the rear of the saddle to the center of the saddle, causing the power of pedalling to pass to the bike.
|2. When the crank arm rotating from 12 o'clock position to 3 o'clock position.
|The power of pedalling delivered to move the bike forward reaches the maximum output and this causes body to move backwards which positions the hipbone to the back of the saddle again. The saddle tilt to the right with the body and the left pelvic bone stays on the saddle as the right foot pushes downward. When thigh inner muscles pushes the side of the saddle, the saddle rotates to the right and this reduces friction between the leg and the saddle, which increases power from pedalling. B3f seatpost has it's inflection point in the middle of the Formega which is designed to prevent absorbing power from pedaling. The elasticity of Formga allows the back of the saddle to move downward with riders weight so it prepares to bounce off to create more power.
|3. When the crank arm rotating from 12 o'clock position to 3 o'clock position.
|AS the rider's body weight and the center of body moves to the left. The elasticity of Formga simultaneously bounces to create more power by lifting right pelvic bone when the pedalling starts on the left. This increased pedalling of power reduces muscle fatigue because less body energy is needed for pedalling. Also, rider are relieved from saddle pain because left pelvic bone and the saddle stayed together. And "From 12 o'clock position to 3 o'clock position" will connect the same movement.
|4. When the crank arm rotating from 12 o'clock position to 3 o'clock position.
|Due to the elasticity of Formga, the occupant's weight naturally moves to the left. And "From 3 o'clock position to 6 o'clock position" will connect the same movement. Pedal operation ends with the left pedal and resumes from 1 starts.
1Saddle and Pelvis Synchronization
2Reduction of Shock
|'Formega' acts as a joint, allowing the saddle to move with the pelvis. Your saddle can also move in 3 Ways (X, Y, Z).
|Formega absorbs the vibrations and shocks created from the irregular road surface, minimizing pain and fatigue.
|The bound pedalling created by the combination of elasticity of FORMEGA and triaxial movement of saddle helps increase power and speed of the bike. It also reduces muscle fatigue.
|'Formega' will help you to bikefit. Improves the pedalling symmetrically caused by asymmetry of leg length, asymmetry of pelvis, unbalanced in foot spacing, and X-legs or O-legs.
|Formega absorbs the vibrations and shocks created from the irregular road surface, minimizing pain and fatigue. Because the bike seat moves accordingly with the user's center of gravity, the slant angle can be minimized during cornering, allowing for increased safety and speed (as pedaling while cornering becomes possible).
|If riders have done urgent breaking, when the bike stops but the rider moves forward by action of inertia. So it keeps a rider from rollover accidents by pressing Formega of the saddle forward with bodyweight of the rider.

|The B3F can only be mounted with a circular seatpost.
|Tuned Seatmast Cap
|Tuned Seatmast Cap is not mounted with B3F. (ex: Trek Emonda, Domane)
