I've been lucky enough to be an ambassador for Trailhead Cycling in Champlin, MN for a few years now. The upshot of that is that I've been able to do long-term test rides of a number of bikes. I've also go (more than) a few bikes of my own. Here you'll find info on both; in the case of loaner bikes, I'll make sure to note it somewhere in the post. Same goes for other borrowed/rented/demoed equipment.
