Thanks, I will download this, though I probably won't get on it anytime soon since we have a cold front coming in. I am hoping I won't need any parts, I am feeling at least 2 separate speeds, I think that means the dynamo must be doing it's thing and the brain is working to some extent. Since I don't know how it's supposed to feel, I am not sure if it is skipping over the middle gear. The easy pedaling gear is extremely easy. I'm looking forward to getting it up on the stand. With the other 3 speed it seems like the middle gear is roughly 1 to 1 on the rpm for the crank/wheel.
