Nukeproof developed their new Rook slopestyle frame featuring an integrated hydraulic gyro head tube. This will be launched on Thursday 19th April at this year’s Sea Otter Classic in Monterey, USA.The integration of the gyro in the head tube allows for a low stack height of just 10 millimeter, including headset cup, which is not possible on conventional frames.
The Rook has a low, mildly progressive leverage rate designed to give a stiff platform for dirt jumping or slopestyle when used with 150+ PSI. Additionally, due to the low leverage rate, the feel of the ride is highly tunable by altering the compression damping of the shock. Switching the shock to its minimum compression position and running below 150PSI provides a supple, active suspension feel for freeride or trail use.
The geometry of the Rook is optimised for a 110mm travel fork giving a 13-inch BB height and 69 degree head angle. Running the frame with a 160 millimeter fork will raise the BB to 13.75-inch and slacken the head angle to a trail taming 66 degrees.
