Foam Surfaces

foam BiSaddle surfaces process

The new outer material is a "visco-elastic foam" as compared to the "visco-elastic elastomer" on our regular BiSaddle®. The foam surfaces have the same contours as the elastomer except for the back lip being lower, they provide a more consistent softness than the elastomer ones, are lighter by 35% and a little less "springy" than the elastomer. The softness may be a problem for a few riders but our police and randonneuer evaluators asked for this softness with this material and the smaller raised lip in the back....the weight loss is an added benefit.

The foam surfaces are being hand crafted by stacking 7 layers of different softness foam, shaping that block to our surface design contours, then applying a 1/32" outer foam layer and finally putting on our 4-way stretch covering. Because making them is so labor intensive, the foam surfaces are more expensive than the elastomer surfaces.

With our elastomer BiSaddle®, the 4-way stretch coverings are optional, but they are required with the foam hand crafted surfaces.

Price of hand crafted foam surfaces is $125.00 plus shipping.

aluminum frame2024 aluminum frame:

The new saddle surface support frame consists of 5/16" diameter 2024 aluminum drawn wire welded together with an extruded, machined and welded 2024 aluminum plate. The wire and the plate are TIG welded together with 4145 filler, subsequently taken to a T4 conditioning and then anodized. 2024 aluminum is rated at 500,000,000 fatigue strength cycles and the frame has been tested to a dead weight load of 1275 lbs. before deforming or breaking.

The aluminum frame weighs 4.7 oz/133 g in comparison to our steel frame which weighs 10.1 oz/285 g.

2024 aluminum

Chemical composition normally includes 4.4% Copper, 0.6% Manganese, 1.5% Magnesium and aluminum including normal impurities constitute remainder.

Principal Design Features: An age hardening, high strength aluminum alloy. Useful for optimum strength to weight ratio structures.

Applications: Commonly used in the manufacture of truck wheels, aircraft structures, and screw machine products, scientific instruments, veterinary and orthopedic braces and equipment, in rivets….and now, not so commonly used in bicycle saddle frames.

2024 aluminum is approximately 2 times stronger than 6061 aluminum.

Price of aluminum frame is $75.00 plus shipping.
There will be a $25 restocking charge on the aluminum frame.
