I now have a shortlist!
Burls custom Ti
Enigma Elite or Extensor (stainless)
Condor steel Accaido or super or stainless or even Ti Gran Fondo
Genesis Volare 20 or even 953 team
Singular Peregine
Surly Racer
Possibly last two are more utility choices?
No carbon there however Condor do a sweet Gran Fondo carbon frame.
I am in the south east so left out Roukes, Shand and Statley
Steel more budget, Ti more traditional and Stainless steel possibly too much strain on the £3k budget?
Last point, how much should I add to the frame and fork price for a total build? Not looking for expensive wheels or group set but need to do the frame justice!
