Reason I ask is that I'm looking at this bike with 700 wheels and was wondering if an Old Man Mountain Red Rock rear rack (ha! the alliteration!) will fit on it. I'm afraid of clearance issues. The bike is a Trek 7.3 FX, size 15".
For the record. Is it 700c or 700cc? The bike comes with 700 x 32c tires. What do the numbers and letters mean? Did a google search and still don't get it because there's conflicting info!
