Does anybody know the weight of the MASI 54/56 CM FIXIE TRACK PISTA FRAME BICYCLE?

The frame in the link is not a 54/56 cm frame. Track frames don't have to be all that light, stiffness is much more important for sprinting. Many track frames are made from a heavier gauge tubing than road frames to enhance frame stiffness. Frame geometry is also important, this frame has a 54cm top tube. The information does not state what frame tubing it is made from, only a generic description of the tubing. It isn't really possible to give the weight.
