got this last weekend. I really like the nexus internal geared hubs, and this was at a good price. really cool seller even discounted the sale price, as he said it needed a seat and tires. so when I got it home, I saw the wheels were taller than on one of my 26"ers, and so it has a 700 c wheelset. doing some research on tires, it has 700 X 35 on it now, so would 700 X 32 be a narrower tire, and 700 X 38 wider?
