Specialized 2010 HardRock I love my RockHopper, probably one of the best bikes I have had in a long time. But it is a 23" frame and being 5'6 it was a challenge even with 3" cut off the top of the seat post I still could not touch the ground. A few times I have embarrassing tumbled over trying to get my foot planted on the ground before my boys got a visit from the top tube in a not so friendly manner. I really wanted another Rockhopper Comp but in a smaller frame. But cost is a huge factor and the Hardrock is the very same frame as the Rockhopper it just does not have the upgraded components. So I got a great deal on the 2010 HardRock and I can always swap the better components of my Rockhopper onto the HardRock.
