I recently purchased an SWB 'bent with a Euromesh seat. On rides longer than 25 miles, my rear end gets sore. The seat is reclined at around 40 degrees from vertical. I also have a V-Rex with a Rans mesh seat reclined at approximately the same angle, and have never had this problem. Does this ring a bell with anyone, and if so, how might it be remedied (other than replacing the seat with a different one). Other than this problem with the seat-induced butt pain, the new bike is great (Barcroft Virginia Ti).
