I have just got bought this Dolan TT 700c/650c with eliptical tubing (the three main tubes are eliptical as opposed to oval and has a fairly distinct front and back edge).
Dolan says it is prob Dedacciai hand built by Terry. It was refinished about 2 years ago and looks like not ridden since.
Any idea on tubing make and type ???
Now re building lo pros are so difficult to work out sizing -I have ridden 53tt and 57 tt and both been fine but this is unusual geometry. The seat tube is about 62cm centre bb to top of tube (so with a cm of post and saddle a min top of saddle to BB of say 70cm. but tt ctc is only 50cm !!
When I fit saddle centre of rails and 120cm stem the tip of saddle to bar next to stem is 54 -only 1cm less than my road bike which has a 56cm tt. How wierd .
Well build up or too small ??? Opinions please
