I have been riding a Fisher GS Tassahara Large for a few years and will be purchasing a full suspension bike soon. I Test rode a medium womens FSR Stump Jumper and am very impressed with the ride. Had to replace the stock 90 mm stem with a 110 mm riser stem to get the proper reach for the test ride. It fit ok but any more seat post extension and the bike will feel a little unstable. I am 5' 71/2" tall and have a 31" inseam. I wonder if the large will be a better fit. Can't find a large to test ride. Any Stump Jumper fit advise would be appreciated.
