I just bought a 2007 Bianchi Mutt 7700. I plan to start racing XC races in my area. I was wondering what is the big difference between fs and ht for racing. It just seems like a fs wouldnt be as fast as a ht. I know they probably are alot smoother through rough terrain. Also the fs that is compared to my ht in components is $1000 more atleast. My friend is planning on buying a bike and is asking the same questions.
