For me back in the day, we rode and raced it was all the same, you turned up and did an XC and a DH, heck you even did a hill climb race on your way to the DH start, all on the same bike, with the same people.
Then after a while (mostly with the advent of FS) you would ahve 2 bikes, 1 for XC and the other for DH, but at any time your XC bike could race the DH and the DH bike could be pressed into service of XC.
Then for me around 97/98 wehn proper DH only bikes were coming around, course got more "narly" and you had to have longer travel and your XC bike would get you injured (killed) on a DH course and in general.
Then my local races and the world cup XC and DH became separate things ant different events.
The you get the problem of, we have suspension, that course is now OK, oh so we get a harder course->get more travel->get harder course->more travel->harder etc etc...
I've come across people that like to ride hard tracks (illegal ones) because they say that normal stuff is too easy on aDH bike, I say go buy a hardtail.
I went to my big race last year (worlds) and watching the XC was simply amazing, seeing the fitness and skills on display, after watching the DH practice, I was so underwhelmed didn't both to watch the finals (also the spectators didn't help).
Also judt for the masses, not the pros, but the attitude is completely different, XC people seem to be, oh DH, nt my thing, Dher's seem to be, what you ride a HT? what for, there is something other than DH, that isn't DJ?
Anyway thats just my thoughts, I'm not XC or DH, just ride around very slowly and wish it was all different, liek in the early 90's :idea:
