Yeah, no slicks on the mtb.

Actually, today a fellow rider brought along his wife's road bike for me today (it came with a disclaimer: he bears no responsibility to my husband should I run out this weekend and buy a bike).

WHOW what a difference! I think I could ride an extra 15 miles no problem. Hers was a 53 inch so I know now, that's too small. I'm trying out a 54 inch on Sunday & we'll see how that feels. Wish me luck.
