I remember seeing that video a long time ago. It's horrible that the DEA would set up a young guy like that for a stupid crime, when there are serial rapists and murderers out there. RIP Sam.
I saw that on pinkbike, and they said it was one of those tricks that you should just use to get back to the trailhead/lift.
I just keep a patch kit and tire levers in my bag.
Rode here last saturday, trails were decent but a little slippery. I was in a DH mood, so i just hiked my bike up the mountain (center trail) and bombed down. Rode in control with no skidding :)
I'm sure you're talking about the derailleur. The device that clamps to your frame and physically moves the chain is the derailleur. The shifter is attached to the handlebars and controls the derailleur. Just lettin you know.
I've had experience with difficult tire/rim combos... I found that standing and pulling on the bead to stretch it out before putting it on helps. More importantly, make 100% sure that the bead is in the dead center of the rim. It makes a massive difference.
All I can say is don't buy skullcandys. I have owned 4 pairs, and all of them have jack issues (and more sometimes). If the connecting piece gets bent in the slightest the sound goes out in one ear. It's the same with all of them. Thankfully Skullcandy has a lifetime warranty and sent me a free...
