Beargrease pairs a race-ready carbon frame with the capability of fat tires for the ultimate groomed-trail machine. Its trail geometry, dropper post, and 27.5? wheels grant you confidence in loose corners and descents and make for an all-season ripper. Frame and fork mounts for extra bottles and cargo make it easier to gear up for your long days out or even overnighters, and the high-performance XT/SLX drivetrain is the icing on the cake. For light-and-quick confidence on any terrain, Beargrease is one of the best carbon fat-tire bikes out there. FEATURES : High-Modulus Carbon Fiber Frame : This material offers improved stiffness, better vibration damping, excellent durability, and weight savings compared to other frame materials Beargrease Geometry : Completely redesigned frame and fork for 2019. 440mm chainstays, longer front/center, short stems, and wide bars create room to move and add confidence while maneuvering on tight trails. Standover height is improved, allowing the addition of a new XS frame size. This geometry results in a fat bike that rides like a trail bike. It is stable, steers well in loose conditions, and still remains nimble and agile despite the massive wheels and tires. A low bottom bracket height is also key, keeping the rider’s center of gravity low, and making dabbing, dismounting, and remounting easier.
