I'm one of the unholies who has used the S40 in a way other than intended. Because I didn't need it for a head/neck rest, I flipped it over, cut off the end 4" of the tubes (to remove some of the arc and allow it to insert into the frame a little longer) and clamped it in place. I mount a standard seat bag on top or bottom and clip rear lights to the bag and tube. I also keep a stretch/velcro band wrapped around it for bringing home the odd bag of bagels or other bits after a ride. Can even use it to wrap up a jacket mid ride after things (including me) warm up. Nice that the CB guys designed it just perfectly for dual duty!
