You always hear about how fast Trek's Superfly 6 is. It's winning this race, it's crushing this course, etc. But that's only part of the story. Even if you never race it, you'll love the light, efficient aluminum frame with Gary Fisher's G2 geometry, the 100mm RockShox Reba fork and the tubeless-ready Bontrager wheels and tires that roll over practically anything. SRAM adds a 2x10 drivetrain with a crisp X9 Type 2 derailleur so dropped chains are a thing of the past, and Shimano hooks you up with powerful disc brakes. Take all of this and add its legendary handling, and you have a completely capable trail machine that just also happens to be adept at winning.
