Hey, TSL- trust me, I'm not also going to start changing chains! I took apart typewriters as a kid (teens) and that was fun, but that was then. I'll stick with what's on what I got. I think I'm going to have my LBS put on the tires this time but ask if I can watch. I used to be a reporter, and that's how I learn best.
thanks for all your help.
And Paul, I'm risking the increased resistance and going for the m&g 160, but appreciate the thought. Hi to my old home town, where I NEVER biked.
