Pompe frame looks good, cheap, but heavy at 2kg+ without forks...I'd rather stretch the cost than have regrets on spec.
Have a read through the Pompino thread. Do you see a lot of regret*? On-One frames are a bit porky, but they work. My Pompetamine gets ridden more than any of my other bikes because its fast enough on the road but I can throw it at the scenery without worry. I haven't weighed it, but I'm sure it's over 12kg. If you wanted it light, a carbon CX fork might knock the best part of ½kg off, and you could easily knock a whole kilogram off my wheels and tyres, plus my brakes are far from light. With careful shopping, you could build a singlespeed Pompetamine or Kaffenback at about 10kg, probably for less than the £1100 mine cost. If you can live with rim brakes, a Pompino would be even lighter and cheaper, but there's still no way you're going to build something tough and sub 8kg for under £1k new.
