Hey there, just wanted to tell you that there is a bike shop in Greensburg. It may be a winner for maintenance or what not. I've never been there, but have heard positive things about the guy. The owner is an avid mountain biker. I think he is open Monday thru Friday evenings only. Anyhow the guys name is Andrew and his number is 270-932-1449. I just thought that may be a local option, since we live in such a rural area. I am a road biker and live in Campbellsville. Take care, Wilson
