I am in search of any suggestions for a cure to the severe pain in my legs that comes from the front edge of the seat pan on my SILVIO CBSV-091. This pan is similar to sciatic nerve pain, in that it radiates distally down the leg to cause an ache in the knee and ankle areas. The width of the front of the pan is hitting the back of my thighs approximately 4 inches below the hip joint. This pain will begin within the first 5 miles of any ride. Pleasure, power and speed, all 3, disappear as the pain sets in and I find myself squirming around on the seat like a restless child in school.
If I could round down the edges after cutting, I think I would cut away a large section from each side of the front of the seat to clear my thighs on the forward/down stroke. Counter-current to recumbent thinking, I have a vision of a standard road bike saddle with the tilt angle adjustable and the existing seat back @ 45 degrees to lean back against. Gasp!!! Yes, it is true I would rather ride on a narrow roadbike saddle than this wide seat pan!
I have moved the stock seat pad forward and back over the pan trying to find a cure, but none yet. With traditional high-racer recumbents the seat can usually be adjusted to fit the rider and by reclining back more the pressure is taken off the buttocks area until comfortable--we don't have this option.
I have reason to believe that if I were shorter (x-seam = 44.5") this might not be an issue, because adjusting the TFT would raise the bottom bracket in an arch and more clearance would be available for my thighs. If this theory is correct, riders my height and taller will be the ones most likely in pain.
If I were giving input on the design of the Vendetta as a time trial bike, seat design would be part of the new features.
Oh BTW, Mr. John T., how does the VENDETTA prototype progress at this time? You are finishing riding season in the southern hemisphere? and we saw a photo of the lovely creation last September at the beginning of warm weather in your half of the world. Hopefully you got a lot of real world testing miles on the proto.
