Finally, my search is over. Won a ridley crossbow frame (too poor for x-fire/night). Going to give Shimergo a try with campy hubbub conversion to 105 RD 11-28 cassette with 40t chainring. Velocity tubulars with some of the $35 vittoria tubulars. Jagwire race cable set (states that is campy compatible).
Should be built up for around $900 USD. There is a site (realcyclist?) selling Tiagra model for 899, but I will be a bit lighter, with tubular wheelset. Should be a decent cx machine
