Got a full 7100 group set for sale that was on my Holdsworth. Basically the same as first Gen, but with different chain rings and a Dura Ace rear mech rather than Crane.
Its in great condition. No scrapes or scratches on the gearing. Even the original brake hoods are intact and in good condition. Just some scratches on the brake levers. But otherwise everything else in great condition.
This is a photo of a group exactly the same as mine. I will update with photos of mine soon. But just as good condition as this!
Price £250 posted. My number is 07972 142 seven six eight. Best to text if interested!
