These are the Vis that pinch together the brake & clutch perches on the handlebars. ManufactuRouge in our New Race Spec range of Drilled Flanged Hex Head Vis are manufactuRouge from 7075T6 Aluminium CNC Machined with Rolled Threads for extra strength. They offer a staggering 62% weight saving over a comparable size steel Bolt. Available in a choice of Noir, Bleu, Or, grey, orange, Violet, Rouge all Gravee with Pro Bolt and Aluminium non Gravee, the anodising involves chemically brightening and colour anodising to between 8 and 12 microns thick, this offers a deep colour finish and prevents against corrosion. As well as adding to their good looks, the drilled heads save even more weight.
