B3F [Bikefit By Body Form]
: Speed Up, Pain Out
The B3F Seatpost includes an elastic rubber suspension that allos the saddle to move in 3-Way(X,Y,Z Axis) in react to the movement of the rider.
How to Work
: How B3F Works
The B3F Seatpost incorporates the Formega, a '3-Way Stabilization' technology, that allows the bike seat to move top-to-bottom and left-to-right together with the thigh and hip muscles, significantly reducing friction between the seat and the hip
Existing Bike Seatposts and Saddles
Problems with fixed saddles
If rider's right foot pushes downward, pelvis tilts to the right as the center of gravity moves to the right and left pelvic bone leaves the saddle at the same time. It reduces power generated from pedalling because friction is created from the inside thigh muscles trying to push the right-side of saddle towards the back. Also riders experience pelvic pain from left pelvic bone because the fixed addle bumped against each other while pedalling from the left.
The problem of shock absorbing seatposts and saddles
When we walk, the width between our left and right feet is narrow, so when we step forward, our pelvis, knees and feet are aligned straight in the direction of gravity.
pedal and left pedal the pelvis, knees and feet are not aligned in the direction of gravity. So the angle of the knee bends inside bcause the knee gets stressd. This condition pedal can cause knee pain and reduced power.
B3F Seatpost
The birth of a perfect solution
* Although the gap between pedalling is large, flexibility of Formega allows the saddle and pelvis move together. This allows pelvis, knees, and foot aligned to the direction of gravity and increases power without injuries.
* It allows extra safety to riders in cornering because it moves the center of gravity naturally either to the left or to the right.
| 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. |
Benefit of B3F
|
|
| |
|
1
Saddle and Pelvis Synchronization
|
2
Reduction 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. | |
|
|
| |
|
3
Bounding Pedaling
|
4
Pedalling Symmetrically
| |
| 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. | |
|
|
| |
|
5
Cornering
|
6
Nose Down
| |
| 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. |
Analysis
: Before and after use of the B3F seatpost measured by power meter
The data below presents a comparison between before and after using B3F Seat Post. A computrainer was used. In brief, after the experiment, participants expressed that B3F reduced knee pain and/or other uncomfort.
The computrainer was used to measure power (Watts), speed (KPH), and number of rotations (RPM) between the conventional seat post and B3F Seat Post.
1
Ms.Eun○ Bak: Lateral(outside) right knee pain.
RESULT: Overall, torque, speed, and rotation were increased. The knee-line posture was normalized. Knee pain was reported to be resolved.
2
Mr.○ Lee: Waist(lower-back) pain and perineum pressure.
RESULT: The knee-line posture was normalized. Lower-back pain and perineum pressure were reported to be resolved.
3
Mr.Jun○ Hong: Waist(lower-back) and left knee pain.
RESULT: The knee-line was normalized. The shoulders became leveled, reducing lower-back pain and discomfort.
4
Mr.○ Lee: The right inner-thigh pain, bent hip, and (left-right) leg length imbalance.
RESULT: The knee-line was normalized. The shoulders became leveled, reducing pain and discomfort.
5
Mr.U○ Kim: lower-back pain and numb feet.
RESULT: The knee-line was normalized. The shoulders became leveled, reducing back pain and discomfort.
STRAVA Records from Amateurs
So, We decided to open a public event.
To recruit a loads of numbers of unspecified amatuer testers on Facebook, and testers have to provide both before and after segment records of riding with B3F seatpost on road!
We recruited testers from Facebook, Instagram and our homepage.
Since then many Korean amateurs gave us joyfulness, support and fun.
Below is one of the STRAVA segment records of testers.
This case shows a best shortening record of Korea's Buraksan Arirang Uphill (distance 5.36km, altitude 239m, average slope 4%, level 3 uphill) which massively shortended 3 minutes from 24:02 to 21:02.
12.5% improvement
In addition to improving your records, B3F will help you to break your PR in a snap as well.
Testers used B3F and had an average improvement of over 10%
Are you still suspicious of B3F? VAZALAB welcomes suspicion from customers.
Now by reading this page, also you can participate in the B3F test.
We will show you the result. It is a matter of what we care about: Nothing is better than purchasing something you really need after experience it.
