I'd echo everything the author has to say there. Also, as he mentions, the handlebar is indeed a 25.4. I just found that out when I changed out the stem. (Seriously, Bikesdirect could not have specced an uglier stem). My new one (Origin8 Ultimat8 120) is a 26.0. A 40 cm eBay drop bar in the 26mm size is on its way for only a few dollars more than a shim would have cost. The stock bar goes in the parts pile for now, along with the ugly stem.
I am continuing to love the thinner, higher-pressure tires. I made a bonehead move and bought replacement tubes in the 451 size instead of the 406 size of the Nano's wheels, but I have been able to fit these tubes with only minor encouragement and they have held up well.
I'm ready for better gearing. I'm thinking about getting an 11-34 8-speed cassette and going with just the 53 ring up front. It's a question of what kind of hills I'll be able to get up in a 53X34 more than anything, but I'd love to drop the second chaining and derailer in favor of short stack bolts and a chain watcher.
