I spent a few minutes re-reading it, and I honestly think Cigtech was a well-intentioned guy who was a little bit of a fish-out-of-water posting in the Road Cycling forum. I think his mistaken sense of speed just added to the crazyness, because every time he spoke about how fast he could ride ("Its flat in florida," etc.), people would kind of get fixated on how unrealistic it was.
I think it was just someone who was willing to keep a close eye on his walmart bike and keep it together. (Although didn't his read derailleur or his rear wheel fall off eventually?)
Now, I *do* believe he really bought a Walmart Denali and rode it. But I also think he embellished the hell out of it because it made everything so hilarious.
That's the beauty of the thread, it was so on the border of being unable to tell if it was a troll. Do recall that he claimed he calibrated his computer on a track and vs. a car - there's no way he was off by like a factor of 2. He was absolutely adamant about this.
It was little things that made it awesome - the fantastic speeds, when he said (dead serious) that he wanted to get in the race to replace Lance, the collision with a car where he bounced off the hood and back on to his still rolling bike, etc. There were a few other things too that were absolutely hilarious.
The funny thing is I'm still not 100% sure he's a troll. But if he's not, he should be, because that thread was fantastic. Either way the guy is a freaking hero.
