It's a road shell, presumably the guides are integral and it's a microfusion cast shell. Probably better than the available plain options. Just another of those cases where road bikes get the advanced technology and track bikes stay old fashioned or adapt road kit for the track.

they looked absolutely identical, just track ends for the pista. a shame and overpriced.
