WOW....i was offline for a few months and missed your thread "where i've been"...just looked it up and i must say HUGE KUDOS to you...there is one inspiration after another around here!!!!
as far as material i can't say i could help but finding out what is used for prosthetics is my first thought...i remember a mention of that when the wounded warriors were cycling across the states, a couple of them lost limbs and had chafing issues...just a thought.
Glad to hear you are back on the bike...pedal on!!!!! but watch out for Christmas trees
I am a nobody; nobody is perfect, and therefore I am perfect.
