Nukeproof Launch Prototype ‘Rook’ Slopestyle Frame
April 27th, 2012
By Factory Jackson in Tech
Fresh from its debut at last week’s Sea Otter Classic, Nukeproof have released some more information on the revolutionary prototype Rook slopestyle frame, a development project between Nukeproof and the company’s newly signed slopestyle rider Jack Fogelquist.
The Rook features an integrated hydraulic gyro head tube which allows for a low stack height of just 10mm – including headset cup – which is not possible on conventional frames. This innovative new head tube feature is set to be a game changer for this type of bike, and the platform will be utilised by Fogelquist throughout the remainder of the 2012 season.
Other features of the Rook include 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” BB height and 69 degree head angle. Running the frame with a 160mm fork raises the BB to 13.75” and slackens the head angle to a trail taming 66 degrees. Chainstays are kept short for pumping tight bowls and manualling.
Pictured above, we have the Rook in long-travel mode with a 160mm X-Fusion Vengeance 2013 fork, X-Fusion O2 RCX rear shock, Trickstuff Trixer hydraulic gyro, Truvativ Descendant cranks, SRAM X0 drivetrain, SRAM RC2 TT shifter and a Nukeproof wheelset sporting a prototype 6-speed ‘short cassette’ hub with 12mm bolt-through axle and wider flange spacing. Finishing kit is also from Nukeproof’s tried and tested component range.
Still in its prototype phase, no price details are available yet on the Rook – which will only be available as a frame-only model – and we’ll be working closely with Jack during the rest of the season to tweak and tune the frame, ready for expected release at Eurobike 2012.
