  • Trail +

Bike Description

The ultimate adventure bike that is taking trail riding to the next level. Plus-sized, 27.5+ x 2.8" WTB tubeless-ready tires roll fast, grip anything and bring a completely new riding experience. A premium Columbus Thron butted and formed frameset features custom, investment-cast dropouts with rear Naild 12-3-9 quick-release thru axle and 148x12mm Boost spacing. Rack eyelets and triple bottle mounts make it ready for your next bikepacking adventure. Suspension duties are handled by a Fox Float 34 fork, a new Shimano XT 1x11 drivetrain helps put the power to the ground and a KS LEV Integra dropper post allow the rider additional clearance for when the trail gets aggressive. It only took us 30 years of trail riding to create the Pine Mountain, enjoy a ride like none other.
