My Univega Gran Premio and wife's Trek 420. We have a short commute so we carry backpacks for now. I would like to get a nice rack for the Trek though as she often has more to carry than I do. Plus she has rack mount bosses. Any suggestions for a rack system that bolts on to a bossed frame? Most of what I see is "retrofit" ready, but I don't want to use clamps if I can mount it properly.
