I race on the track and am considering both of these framesets. Does anybody have any opinion between the two? I know the KHS is the same as the mercier kilo tt which I know a few people use where I am. The KHS is $188, the eighthinch is $150. I know eighthinch updated their geometry for the v3 by raising the bottom bracket up a bit for added clearance. Does anybody use one or the other for track racing?
