CigTech has been posting his speed in this forum for as long as he's been here. Long before he started this thread. I see no reason to doubt that he maintains speeds pretty close to what he claims. But if he is fabricating the speeds or stretching them - it's not because of this review. He claimed speed like that before this review too. My opinion is that he posts what he sees. Search the forums and see. He claimed fast speeds before this bike. He's in flat Florida. He posts higher and lower speeds - not always record breakers - but they are always fast. FWIW
