M5 Lightweight disc hubs
Never done before anywhere in the world: disc brake hub set (front) of less than 100 grammes. With just 99 grammes we now have the most lightweight disc brake hub in the world. Incidentally, also one of the most rigid hubs ever too, thanks to the large diameter of the hub housing. Furthermore we introduced a rather revolutionary disc placement: the six cut out, dirt collecting "lobes" are completely absent. The bearings have an extra seal by means of two rubber rings around the 15 mm hollow axles. This extra sealing provides an even longer lifespan of the bearings. Like al our lightweight parts, the hubs are laser engraved with the M5 logo, and have been anodised black or red. Available in 32 hole version, This set of hubs combines excellent with those splendid, new designed 40 mm high ATB rims by M5!
