Hardtail energy usage

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?

Joe

When your on a real bumpy section, are you sitting on the saddle? The best suspension is your own legs. When going over bumpy areas, dont sit and you will be fine

That's what I think is eating up the energy. I'm out of the saddle for most of that ride using my legs as suspension where my buddies on the FS are taking it easy in the seats and letting the bike suspension handle the bumps, thus, I've used more energy then they have. Is my logic flawed in any way?

Pretty much on target. While a case can be made from an engineering standpoint about the energy loss from rider input to the rear wheel on a FS frame vs HT the overall affect of the terrain takes a toll on the energy level of the rider on the HT.

Which do you think would take up more energy, though, a bad FS bike or a HT?

That I think would depend on the terrain. I think one reason I was able to keep up with these guys on hills is because I was on a hardtail (they were on fuel 100 & fuel 95). That and that I do a lot of squats and lunges.

also, picking the best line helps as well. I see people just plow over roots/rocks when they could steer their tires around them, giving a smoother ride.

or even 'pumping' on the backsides of some small slopes or whatnot, can increase your speed.

what shape are you in? what is your skill level? etc.. this will have an effect for sure.

also, I would suggest a camelback type backpack. that way you don't have to stop for water, you can sip as you ride.

I would say a bad FS bike would take up more energy. I took a entry lever FS bike out for a try. Just around the block of my LBS. It felt like I was riding that slinky dog from toy story.

My stumpy does a good job cancelling out the pedal bob, i know its still there, but i remain seated in alot more situations, and i conserve energy. A good quality FS will be able to cancel out alot of pedal bob, the fox shocks now come with pro pedal dampeing which helps even more. I say i use less enegry riding my FS than i did riding my hardtail, although i do sometimes miss the HD on a really long climb..but the downhill after with the FS makes me forget all that..
