There are two upgrade SIZE options with these oversize mountain bike brake disc conversion kits – 160/165mm-180mm (medium power upgrade) and 160/165mm 203mm (mega power upgrade) and the option of full circle profile or new lightweight contoured profile.These mount on most standard 6 bolt wheel hubs and together with the bracket provided, which again fits most 50mm centre forks, your caliper is relocated outwards giving you a stronger brake and better brake feel.

Easy to fit – no other changes are necessary to your caliper, cables, hydraulics or lever. All you need are two allen keys.
These are premium quality heat treated stainless steel discs, diamond ground and compatible with every type of mountain bike brake pad. Kits are available to convert standard 160/165mm up to 180mm or 160/165mm to 203mm or 180mm to 203mm.
