Frame: Scalp



Battle scars not included.

For 2013 we continue to offer our highly regarded Scalp DH frame which now presents unbelievable value and brings high performance to the masses in an affordable package!

Taking its name from the legendary downhill track at Moneyscalp Wood in Co Down, the Nukeproof Scalp is our original DH race rig offering 209mm of progressive rear travel via a pull-link driven single-pivot suspension system.

Ridden through two tough seasons on the DH World Cup circuit by the riders of Team CRC/Nukeproof, the Scalp is a race-proven speed machine within the reach of all riders.

Built using T6 6061 aluminium with custom triple-butted hydroformed tubing for a perfectly balanced strength to weight combination, the Scalp is a slack and low-slung gravity sled built for the steepest, most technical and most challenging race runs the sport can throw up.

Boasting a super-slack 63-degree head angle, 47.12” wheelbase and +17mm BB height (medium size) the Scalp is characterised by its centrally-positioned shock and linkage system to keep the centre of gravity low and handlng sweet.

Rear hub spacing is standard 150mm while BB shell width is 83mm. The 1.5in headtube can be used in conjunction with the latest generation of Nukeproof headsets to cater for OS 1.5” steerer forks, standard 1 1/8” or tapered steerers.

Progressive platform

Suspension-wise, the Scalp uses a single-pivot configuration with a unified rear triangle for optimum strength and stiffness. Its pull-link driven Fallout Linkage drives the shock in a three-stage progressive action - progressive throughout, with increasing progression at the beginning and end of the stroke, but a linearly progressive midstroke to avoid any spikes in damping.

Huge 40mm diameter main pivot bearings are used with bearings mounted in machined faces in the swingarm, to provide maximum spacing and stiffness. Twin dogbones pull, rather than push, the swinglink giving a perfect progression rate, and allowing ride height tuning by swapping for different length links.

The Nukeproof Scalp. Leave it all on the hill.
