Nukeproof SCALP FRAME (2012)
Taking its name from the legendary track at Moneyscalp Wood in Co Down, the Nukeproof Scalp is our eagerly-awaited DH race rig, offering 209mm of progressive rear travel via a pull-link driven single-pivot suspension system.
Designed and built with the target of grabbing podium places on the World Cup circuit, the Scalp is nonetheless destined to appeal to weekend warriors everywhere as a top-quality but affordable speed machine.
Engineered from double-welded 6061 aluminium and tested by our team riders on courses in the UK and elsewhere, 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 in wheelbase and 14” static BB height (medium size) the Scalp is characterised by its centrally-positioned shock and linkage system to keep the centre of gravity low and handling sweet.
Rear hub spacing is standard 150mm while BB width is 83mm and the 1.5in headtube can be used in conjunction with the latest generation of Nukeproof headsets to cater for standard 1-1/8in fork steerers.
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.
Shock is a 240x76mm giving 209mm of rear travel, with a Rockshox Vivid R2Ccoil unit as stock on standard frames and Cane Creek Double Barrel as an upgrade option.
The Scalp is available in a choice of Anodized Black, Anodized Silver and Nukeproof Yellow finishes.
