Is this freehub a Shimano or Campagnolo type? I'm looking at purchasing a used Fulcrum Racing 5 wheelset to go with my Shimano 10 speed cassette.

The seller is unsure if the freehub is Shimano or Campagnolo but has provided pictures. Does anyone know which freehub this is? Will only the Shimano freehub work with my Shimano cassette?

Comparing images, I'd say that is a Campy freehub. Shimano Hyperglide freehubs have shallower splines.

Personally I'd be a bit cautious about a seller that doesn't know or can't provide details about the wheels.
