I took my old Trek 720 in to get a tire replaced and to have my gears "adjusted" (actually, I had no idea what was wrong with my gears, they just weren't working right). The repair person convinced me I needed a new gear box and chain. I think the whole thing, including a new tire, came to about $200.00, and it was like I had a brand new bike (they even cleaned it up so it shined). Not only does the bike perform better, but it looks better. I appreciated the knowledgeable repair technicians and their friendly attitude. I bike heavily in good weather so I really appreciate good service delivered with a good attitude.
