It'd be hard to get any more cross country than a Les 29 Carbon X01 with SRAM, FOX, and DT teaming up to keep things light and fast. And, while the Complete Mountain Bike build is a contributing factor to this, Pivot's extensive research, design, and exclusive technology is the primary reason. First off, it weighs less than 2. 5lbs. That's light, and it wouldn't be possible without Pivot's hollow box, high compression internal molding technology the same process that's used to create the Les' signature shape. This allows for greater compaction and smoother internal walls in order to produce a lighter, stronger, and highly optimized frame. The top tube and seatstays are flattened compared to the large down tube, creating a leaf spring like motion to dampen the ride. This shape, however, is wider along the Z axis, so it won't flex side to side while sprinting. Adding to the ride quality are stout chainstays that have been mated to a 92mm PressFit bottom bracket. It's here that you'll find SRAM's X01 GXP with a 30t ring that spins a 10 42t X01 cassette. These ratios perfectly match the larger diameter wheels while optimizing clearance for log crossings. On the opposite end of the chainstays, you'll find Pivot's Swinger adjustable dropout system with a 12x142mm thru axle tying everything together. The Swinger dropout allows you to lengthen the Les' short, 17. 1 inch chainstays in order to adjust handling characteristics. Or, if you've the gumption, to drop the gears for a single speed setup. At the front end of the Les, a tapered head tube is graced with FOX's 32 FLOAT 29 FIT CTD Trail Adjust with Kashima. This gives the Les a 69. 5 degree head tube angle a welcome break from the steep, traditional angles of race bikes.
