Ok, it's time to start talking down to me a bit cause this is a little over my head.
I take all my parts and put them on a steel frame. Take the bike out to Alafia and hit Rollercoaster. What is the first difference that I'll notice? Or do you have to be the guy who is fully in tune with his bike in order to feel much?
Also, do they make steel frame FS bikes or is more of a HT experience?
What you will notice is that the ride is not as harsh or as rough feeling. The tubing absorbs more of the vibration from the trail and it tunes out the chatter better. You will fatigue less and be able to ride longer. I have not heard of any FS steel bikes, but that doesnt mean they dont exist. IMO its more of an HT or fully rigid type of thing, or a guy who wants a nice custom bike that he hopes to keep forever.
Most guys who ride Carbon or Aluminum (like my team mates that race XC for example) they sell their bikes and get the new model every season.
Carbon rides pretty sweet as well and it does help to take out the chatter of the trail and they make every type of bike out there in Carbon I know that for a fact.
