Fundamentals is a How To DVD for Downhill riders. XC and freeride mountain bikers should also somewhat benefit. The riding lessons/techniques are for advanced riders. If you consider yourself a border line expert, then purchase this DVD. The footage of Sam Hill and Greg Minnaar will blow you mind! Their style and blinding speed should inspire (or maybe discourage some of you) from getting on your bike. Lucky thing my DVD player has a "super slow motion" control. After watching and learning, you are guaranteed to ride your bike at wanna be World Cup level speed. This DVD also teaches how to build a complete "all mountain" style bike! The bonus footage alone is enough of a reason to buy. From the same people who bring you "Sprung and Earthed", 4130 publishing: Fundamentals!
