The ONE+ is the zero-compromise XC racing machine from OPEN. Boost; a BB92 bottom bracket and OPEN's Thru-Thread thru-axle, the drivetrain increases in stiffness from the original O-1.0 while new Wire-stays improve vertical compliance and traction. A dozen tweaks later, the ONE+ is a much much better frame than what OPEN ever thought possible. Boost also increases tire clearance meaning it now fits a range of 29er XC tires and 27.5+ semi-fat tires. The ONE+ fits tires up to 29 x 2.4" and put to 27.5 x 3.0" for M and L as well as up to 27.5 x 2.4" & 26 x 3.0" for size S to ensure a 6mm clearance between tire and frame. Weight (frame only): - Size Small: 848g - Size Medium: 869g - Size Large: 885g IN BOX: Frame, headset, seat tube collar, rear thru-axle, 2 rear derailleur hangers, 3 MultiStops (2x, 1x, Di2), chainstay cable exit stop, BB guide, cable sleeves, noise-reduction foam sleeves, bottle cage bolts, manual.
