Does someone here know the Ovalmaster's seat tube dimeter??

I need to know because i'm now "shopping" for a seat post and a seat clamp!

thank's a lot!

OLver,

It is very likely to be 27.2mm as all Colnago's that I am aware of are built to that dimension.

If you have a 'clamp on' (not braze-on) Front Derailleur, and it is 31.8mm, the seat tube diameter is 27.2mm

thank you very much!
