Mike is some sort of oracle. John and Bryce refer to Mike like he's Wikipedia. Mike knows everything, but from what I've observed, he especially knows everything about STI levers, Brooks saddles, rivets, touring bikes, racks, and fenders. Five minutes chatting with the guy, and I learned more than I have from all the touring blogs I've ever read. Also, he magically fixed my non-functioning, 10+ year old STI shifters and made sure the rest of my bike was properly adjusted before returning it to me.
