The Radio Griffin Pro 26 is a competition level dirt jump and slopestyle frame built around Radio's own COMP hydroformed 6061-T6 alloy tube set, butted, tapered and shaped to keep the weight down without giving up stiffness. Twist resistant pyramid chain stays and seat stays hold things steady, a forged yoke opens up tyre and sprocket clearance, and the forged 135mm OLD dropouts run 10mm slots with an IS disc mount taking rotors up to 185mm. The head tube is CNC machined, tapered IS42/IS52 and drilled for gyro/rotor tabs, and the frame takes a 30.9mm post with a Radio Swat clamp included. The Crankstopper bolt system is also included: note that it is only for slowing crank rotation during tricks, it should not be tightened for normal pedalling, and it applies pressure to the bottom bracket sleeve rather than the crank axle, so check your sleeve regularly. Recommended fork travel is 80 to 140mm and it fits up to a 2.30" tyre. Available in black or purple, 22.8" top tube.
