Well time to get back on the bike for another go. 5'11" 275. just turned 56. I ride a Trek 7.3 . Summers in Florida with the excessive humidity just kill it for me. Last year I got 10 off then got a pinched nerve in my neck. Ended up with a steroid injection in my neck to kill the pain. put the 10 back on. Off to the Pinellas trail this weekend.
