Grimeca Alloy Calipers. These alternatives to the originals can be fitted without any modification. They weigh approximately half as much as their cast iron counterparts & can be used on either side. They can also be used as part of a twin disc conversion. Please note that the original chrome caliper cover requires modification before being able to fit either of these calipers - but when they look this good, who wants to cover them up?

Norton Commando Floating Disc. This 12" floating disc conversion significantly improves braking in the Commando disc models. It uses the standard slider with the caliper mounting plate No:MP2 & any one of our alloy calipers. The disc is produced from close-grained cast iron attached by stainless steel rivets with a floating mount to an alloy centre piece. The small degree of disc float ensures smooth brake operation. The whole assembly weighs in at just under 2kg compared to 2.3kg for the standard 10" disc.
