Holy thread resurrection (apologies - not logged in here for ages!)
I have a Drössiger CX bike. Frame was pretty cheap, but quality seems perfectly fine. Was considering a hardtail too, but that would be just for easy trail riding or commuting etc., and nothing hardcore (have a Cotic for that).
If still in the market for one...
Can get the frames cheaper from
http://bike-x-perts.com (that's where I bought mine).
Can get Vortrieb branded frames, which are the same thing as Drössiger, for even cheaper prices from
