I haven't been riding too much the last couple weeks after the MS150. We could meet up on a saturday at some point- send me a private msg.

You also might want to check out massbike.org- they have some good bike safety classes that are good starter classes for getting used to the road again.

I've heard good things about Cycle Loft in Burlington, but other than that don't know shops up your direction. You should probably be looking at something like a less aggressive road bike- something like a Jamis Aurora is popular for the kind of riding you're talking about. A good shop should be able to help you figure out what kind of bike would be best and they should provide a full fitting as a part of the purchase. There's lots of threads on first bike hunting. I unfortunately didn't find this place until I already bought, but happened to get a bike close enough to the right size that I could modify the fit and get where I belong.
