In reference to the video where people keep f*cking themselves up...
I do freeride/downhill mountain biking, so I'm no stranger to getting wrecked. I've done some extreme sh*t, like 30 foot drops, huge jumps with 20 foot gaps, and shore riding (where you ride on wooden structures that are very high off the ground and which are designed to test your balance because everything is extremely narrow, sometimes only as wide as a 2 inches). I'm not bragging, I'm just saying...if you want to be a good bicyclist, you have to be willing to f*ck yourself up.
Well, maybe not if you're just riding on pavement on your cruiser or whatever. But if you want to be a skilled mountain biker, you have to push your limits and accept that you might get wrecked. When I used to race downhill, I would go anywhere between 50-60 MPH down a mountain. My favorite spot is Whistler in British Columbia, Canada. Easily the best mountain biking trails for serious riders, with ski lifts that take you up to the top. Somehow I never broke anything...never even sprained anything...but I've pulled some muscles and ate sh*t tons of times at crazy high speeds, getting deep cuts and scrapes, bleeding everywhere. Got a concussion once or twice.
When we ride freeride and downhill race, we always wear dirt bike helmets (full face), knee pads, elbow pads, and chest/back protection, armored gloves, and clip in pedals so that the intense vibrations from blasting over rock fields won't cause you to lose your footing.
Anyways, that's my rant about the importance of getting wrecked for those of you who are actual mountain bikers. It builds confidence. If you aren't wrecking yourself, you aren't pushing your limits. And if you don't push your limits, then you aren't going to improve beyond your "comfort zone." Go faster, go harder -- smartly and safely -- so that your comfort zone elevates every time you ride. If you do something new and out of your comfort zone and you eat shit, then sack up and try it again until you get it. You'll stop being afraid and, instead, become talented and courageous.
This is my aluminum love child, my Rocky Mountain RM7. You wouldn't know it, but she's been in a ton of wrecks. She's Canadian made, only a small number of this bike produced every year. It weighs 32lbs and has 12 gears, hydraulic disc brakes, 3" wide tires, 26" diameter wheels, and 7" of suspension in the back shock (spring and hydraulic) and 7" in the front fork (hydraulic).
Shit. Now I'm bragging.
