And one more silly tip: I have loaded those baskets so much (grocery shopping), I broke the bottom part of the rack, where the rack "stays" are welded and then attach to the frame. One of the people who works at the LBS suggested a hose clamp as a fix. You can see it, albeit not clearly, in the picture I posted, on the right side, in front of the seat stay. It has held together very well. Anyway, you'd think racks should be able to take the weight by design...
The baskets get warped with the weight, but the LBS straightened them the last time I took the bike in for some annual TLC.
