Excellent job! Getting started is half the battle. Keeping it up is the other half. Now pull off those crazy huge reflectors, get some good lights, fenders, maybe a rack and panniers and enjoy commuting! I'd personally want to do something about the weird cable routing out of those brake hoods, but I know that's how they were "back in the day". Not sure there's any easy way to change it, without changing a ton of stuff.
*edit* [MENTION=334484]deadllama[/MENTION] well hello there fellow Memphian! I'm not in Memphis proper but still in and around the area all the time. I rode some of the Wolf River Trails for the first time on Tuesday morning. What areas do you ride through to get to work?
