In 12 years of coaching mtb skills I still cannot get over how closed minded mountain bikers can be! "Oh, he is a single speeder, they always...", "damn downhiller's with 8" of travel, of course they can ride that section, no skill, the bike does all the work, bet he can't climb to save his life", "look at that idiot on that fully rigid bike doesn't he know...", etc. Well, we are doing the exact same spot! Riding bicycles off road and guess what? The Core, Fundamental Skills are All The Same no matter what kind of mtb you are riding!
Why is this important to you? Because if you want to improve you can learn a lot from riders that are different from you. The skill it takes for Greg Minnaar and Mitch Ropelato to corner so well is the exact same skill all mountain bikers need, regardless of the bike they are on or the label they give themselves.
So open your mind and stop labeling people/riders/things. You can learn from our examples/videos/coaching even if the example we us is on a much different bike that yours. We are fortunate enough to coach many of the best races in the world in all disciplines of mtb racing and we teach them all the same core skills (although in our downhill camps we don't teach climbing skills as climbing on a 40lb bike isn't much fun!).
Yes, we taught singlespeed World Champions Ross Schnell and Sue Haywood the exact same cornering skills we taught World Cup downhill racers Mitch Ropelato and Jackie Harmony.
