Ugh... even after the bike's tuneup, I still have to make my own personal tweaks. The seat was causing me a lot of pain so I had to change to a wider seat. After taking a ride, I had to readjust the seat position because it was too far forward and too low. Then after I got it just where I want it, the handlebars started twisting in their clamp due to the weight I was putting on them, so I need to pick up a set of alen wrenches and tighten down the clamp. I can just avoid putting so much weight on them until I get it fixed, but it's still annoying.
On the plus side, with the seat change, my riding distance has increased a little bit. Now I can ride twice a day without worrying about feeling like my butt bone is grinding into the seat.
