Thanks Grasschopper - it takes a silly big front derailer clamp. A 34.9 I think. I maybe get a braze on dura ace and then get a clamp to braze adapter - my lbs has one.
When you're down here you'll have to give me a shout. Maybe go for a ride w/2Roadies and I - and anyone else that wants to come along. Bring your climbing legs.
