Reading the "Rick Mayer seat thread" Someone mentioned no more sore back. Well I haven't had that problem till lately, but just returning from a 6 day short trip 'bout 1500 miles (didn't ride two of these days) I have returned with a sore back? Am I getting old or has the bike changed (most likely both?)? I know the seat is in process of giving up 86K. Said all that to ask is this a problem with others and if so what seem to be the solution.
