I've got the seat height on the Marin dialed in, I think. The new seat still hurts but it also still has that feeling that once it's broken in, it'll be awesome.
It's still not perfect, and the more I ride, it's nowhere near great. I swapped the bars out initially because I had a lot of shoulder and back pain, and now that I'm not hyper-focusing on my knee, I can feel the same tugging between my shoulders and the same lower back pain.
I took it out for a short ride today, trying to pay close attention to the things that bother me, seeing if I could figure it out without bugging a bunch of other people. If I can get more upright, it eases up. If I lean forward more--as if I were riding with drop bars--it eases up. Yet if I change the bars again, I may be back to square one, dealing with my knees because the overall geometry will change.
I've hit the point where I kinda want to sell this bike, and sell the older Raleigh, keep the Townie, and look for a more upright bike with more than 7 speeds. The downfall of the Townie is the gearing and its weight; 99% of the time it doesn't matter, but if I hit a hill, I'm gonna have a bad time.
After the short ride on the Marin, I grabbed the pink beast and headed back out, and it was nothing but fun. I need that, but without the motor.
I've been eyeing the Electra Townie Commute--upright and 27 speeds--but I have to clear garage space before I can even think about it.
