Fresh from its debut at last week’s Sea Otter Classic, we’re pleased to bring you more information on the prototype Rook slopestyle frame, a development project between Nukeproof and the company’s newly signed slopestyle rider, Jack Fogelquist.
Integrated Hydraulic Gyro: The Rook features an integrated hydraulic gyro and 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.
Suspension: 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 150psi or more. Additionally, due to the low leverage rate, the feel of the ride is highly tuneable 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.
Geometry: 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.
Nukeproof fitted a SRAM RC2 TT shifter placed on the downtube to shift through the gears, allowing the rider to take full advantage of the gryo and not worrying about tangling the shift housing.
Pictured above is the Rook in long travel mode, with a 2013 160mm X-Fusion Vengeance fork, X-Fusion O2 RCX rear shock, Trickstuff Trixer hydraulic gyro, Truvativ Descendant cranks, SRAM XO 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 and being tweaked and tuned by Jack Fogelquist, no price details are available at this time. The Rook will be available as a frame only when it is released at Eurobike 2012.

I didn't have a pic to share but found this....check out the bit that mounts on the down tube.

We didn't figure out the hydraulic gyro but we did get the first gyro built for the cable pull of a disc / v-brake (longer pull than BMX).
