Mounting the Bisaddle®

Integrated seat post clamp that is very adjustable — a high end option for good rotational adjustability.

Above is an old style seat post clamp. If you have an exercise bicycle that has a seat post with a round-shouldered top about 7/8 to 1 inch in diameter, this clamp will work to mount the BiSaddle®. We can sell one to you for $5.00, or you can buy it locally

BiSaddle® saddle fit factors and suggestions

Bicyclists should understand that it may take 100 miles or more to determine if the saddle can work for you and to arrive at optimal settings.

Riders should mount their bicycles on a bicycle trainer for initial saddle adjustment.

Riders should initially set the surfaces to the suggested starting positions.

BiSaddle mountedDuring the adjustment process, move one or both sides, in the front or back, in increments of one-eighth inch. These adjustments can be made in or out, depending on how the rider feels. The goal is to achieve the most comfortable placement of the surfaces (NOT necessarily directly under the bones). Another goal is to have your weight spread on both the V bones (ischiopubic rami) and the knobs at the ends of the V (ischial tuberosities). Some customers have called the proper feeling “cup-your-bones”. Be open to being asymmetrical.

Minor adjustments are expected during subsequent riding sessions to maximize comfort.

It is suggested, at least during the initial fitting of the saddle, that the rider eliminate all forms of padding from their shorts. This will help the rider feel most clearly the positioning of the surfaces under their ischiopubic rami and ischial tuberosities. The design intent of the surface material and hardness of the BiSaddle&® saddles was to eliminate the need for padded shorts, but some riders prefer padded shorts once the saddle is fit to their bone structure.

Suggested rotation of the saddle is 5 to 15 degrees down from level in the back. The inventor has his BiSaddle® rotated to 14 degrees and his handlebars are at the same height as the saddle. The inventor can also place his palms on the floor in a standing position.

As you rotate the saddle backwards, be aware that you may need to adjust the saddle height to maintain proper leg extension. You will likely need to raise the handlebars to comfort relative to the rotation you can achieve. The variations in the saddle rotation, placement of the saddle over the pedals and distance from the saddle to the handlebars affect what leg muscles are utilized most and how comfortable your neck, shoulders, arms, and posterior are.

The ability to adjust both the front and back of the BiSaddle® saddle should embrace all pelvic variations. Adjusting the saddle to fit you most comfortably is only part of the overall bike fit equation. Leg extension, rotational angle of the saddle, height of the handlebars and the distance from the handlebars to the saddle for each person is individual.

Each BiSaddle® rider needs to take ultimate responsibility for saddle adjustment and overall bicycle fit.

If you have questions or feel that the saddle should be more comfortable, please contact us or seek professional fitting assistance. Experience has shown that, for women, the angle of the surfaces may be less than the 80 to 90 degree setting to provide proper comfort. The surfaces can be adjusted anywhere along the slot positions in the front and then within a range of 45-degrees of rotation in the back. This should provide most men and women riders with a combination of surface adjustments that works well for them.
