So I was on a ride yesterday (on my hardtail) with some guys on FS. I had no problem keeping up on the hills and they obviously were taking me on the downhill section for control reasons. The thing that bothered me was some flat bumpy riding. It wore me out increadibly! I wanted to puke after about 2 miles of this. A little break and some water and I was ready to climb with them again.
I guess my question is, Does anybody have any edumacated guesses as to the difference in energy usage differences on just flat but bumpy road between Hardtail and FS.
On another note...I've got a lead on a Giant VT at a good price. Does anyone have any experience with that bike?
