That said, on my old bike the rack was close enough to the seat that putting a basket on left very little clearance between it and the seat. I didn't like it. My current bike has a longer wheel base and the rack sits further back from the seat, so it's probably ok but I don't have the topeak rack to fit my basket any more.
