Oh, I was told by the original owner that these were later with the grub being earlier - I would have thought the engineering problems exposed by the grub screw was an original design with the more conventional seat clamp a solution to threaded/ seized/ sheered grubs screws
There was a problem with the earlier vitus 997 with the conventional seat bolt,in order to stop the seat post from sliding down you had to do the bolt up very tight which inevitably caused the bolt to shear.Vitus answer to this was the grub screw,which at the time was considered really clean and aero,however 20 years plus latter ,seized and rounded out socket heads,not so clever :cry: .I suppose they should have just fitted a separate seat post clamp,like all alloy frames have now,ah well call it Gallic charm
