Hope Floating Centrelock Disc - Constructed in two parts, aluminium centre and stainless steel braking surface. - High performance disc, allowing the stainless steel outer to expand separately from the centre and handle high temperatures without warping. - Hope floating rotors have a true floating design which allows 1 degree of freedom. This means the outer is always free to expand when subjected to heat. - Lightweight design. - Aluminium centre acts as heat sink keeping disc temperatures lower. - CNC machined centre is stiff and lightweight so has the advantages of a thicker fixed disc without the weight penalty. '- Centrelock fitment - Available in: Ø160, Ø180, Ø200, and Ø220mm sizes. - All rotors come with relevant hardware to fit to hub - Centres available in: black, silver, red, blue, purple and orange - Weight 180mm: 146g
