Dear Dan, I have encountered this problem and a similar issue with a too-tight stem after rechroming a fork. The solution was to find a small diameter "Flap-wheel" (small flaps of course sandpaper bonded to a mandrel) - a good hardware store should have one, which I chuck into my drill. I have one which is one inch (25.4 mm) in diameter and can be compressed to fit into the seat tube. It takes off much less material than a reamer and is also cheaper. Great for removing those burrs that booger up a stem or seatpost too. Rod Handsfield, Wichita, Kansas
