Road wheel sets

The other point with handbuilts vs bling low-spoke-count factory wheels is that although handbuilts may come in broadly the same weight or slightly heavier for the money, their rotational mass tends to be very good. E.g. they have light rims (far away from the hub, where it matters cos it's spining) compensated for by more spokes. Rather than less spokes, compensated for by a heavy rim.

A good point. It is easy to get the weights for standalone rims (Open Pro, DT etc, ) but finding the weight of say a rim on a Fulcrum wheel is almost impossible.
Is this because the makers don't want us to know...
