its a thorn Raven Sport. The shifter did give me a few headaches, but that option seems to work well. I have bar-ends on my audax bike: shifting using this is basically the same operation as bar-end. If your used to STI or Ergo you may find this hassle, I dont, though I have hit my knee off it a couple of times, I think thats the biggest issue I have with it. I'll trim down the head tube a bit in a few weeks, still finding my position on it. The ecc.b/b might mean I need to be able to adjust bars as well though. Am impressed with Tekro v-brake levers and edelux headlight. Too early really to say much about the bike, but it seems to ride very well, if slow: I'm very happy with it so far.
