The outer material
is a "visco-elastic foam" as compared
"visco-elastic elastomer" on our
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
35% and a little less "springy" than the elastomer. The softness may
problem for a few riders but our police and randonneuer evaluators asked
this softness with this material and the smaller raised lip in the
back....the weight loss is an added benefit.
The foam surfaces are hand crafted by stacking 5, 6 or 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
With our elastomer
BiSaddle®, the 4-way stretch coverings were optional, but are
required with the foam hand crafted surfaces.
