I'm a little perplexed by the notion that downhillers aren't cyclists??
I've ridden road, XC and am now downhilling, and I would be the first to admit that although I can cane around the mountains all day on a XC bike, After 5 Mins of intense downhill action, my entire body is completely pumped.
Its the most intense cycling i've ever done.
To top it all, skills wise, by the time your half way down and your body is burning, you still have to be able to lay it on for the big jumps, and technical sections when all you want to do is sit down and rest your calves and forearms.
If you knew any downhill racers, you'd find they are athletes. They train in the gym, on the road or XC as hard as anyone who races any other discipline.
You may think gravity is doing the work, but you'd be wrong.
Oh, and you don't see many DH bikes with 20T rings......i think the norm is around 40T. And if you'd ever tried even pushing a 40lb + rig to the top of a mountain, you may have some idea of exactly how much work is involved.
It's easy to sit down and plug away with a cadence which is comfortable on a 20lb bike.
All said and done though, one of the good things about riding of all disciplines is that the people by and large are pretty cool anyway.
I've found the DH boys and girls to be very laid back, and even the big boys who are amazing to watch, are very understated about themselves. Maybe thats what comes from actually respecting your discipline, and knowing that the courses you ride have the ability to turn nasty at the slightest drop of cencentration, and to take anything for granted is the way that accidents happen.
And whats up with BMXers?? If you saw how much they practice to get as good as they are, maybe they'd be given a little more respect as brotherins.
I could only wish that i had the kind of skills it takes to do the stuff you see even the kids doing.
And its great to see that cycling in some guise still appeals to the youngsters
