Dolan Seta, not in their site yet, carbon fibre, £800 -
found via tokyofixedgear;
"This is the new Dolan Seta. A ultra light track carbon track frame for £800. And its not any of that open Taiwanese open design bull, this is a Dolan original design made for longer track disciplines & even to their own admittance a great frame to ride on the road. By "on the road" I mean on the road, not off fun box's or even curbs. This frame also has a custom colour way, more of these will be coming a custom colour's can be ordered."
for £800, I'd get this over the Cinelli MASH, pretty light at 1200kg for the frame.
good price, ice looking frame too
