These are the most important points in the article:
"Trek purchased, from another supplier, a fixed number of special wheels, one of which was for Alberto. However, someone in Alberto's entourage noticed that Lance's wheels had the LiveStrong logo painted all over it and told AC that these wheels were better than his. Alberto took notice, called Trek and bought other wheels."
"It all started the day before the Tour, when one of Astana's mechanics that were putting together the TT bikes noticed that two of the back wheels provided by Trek were different from everyone else's. Not thinking any of it, this mechanic went on with his business thinking that one of the wheels was for Alberto and the other was for Lance, but upon using one of these "special" wheels to assemble AC's bike he was told by the Trek mechanic that both wheels were for Lance, although he had nothing to worry about because they were the same, only the logos changed. Without hesitation, the Spanish mechanic took one of the wheels and wheighted it. Since these two wheels were 150 grams lighter than the ones Trek had provided everyone else with, the mechanic took one and said 'one for Lance and one for Alberto', to which the Trek mechanic replied 'I'll have to talk to Lance first'.
Seeing that there was someting very wrong with this situation, the mechanic told this person to not worry about it. And, after talking to Alberto, the later thought that a wheel wasn't worth fighting over and decided to buy his own wheels, the very same wheels Lance had. Without wasting any time the mechanic called the provider and bought the wheels for AC for 5.000 Euros (~ USD 7,000.00). The wheels eventually arrived before dinner that very same day and were applied pastic, the special glue that is applied to the tubulars and were left to dry overnight. The next morning, the same day of the start of the TdF, Contador's mechanic gave the two extra lightweight Lightweight (the actual name of the company that makes these special) wheels to the Trek mechanic to paint the Bontrager logos on them. And this is how AC and LA ended up starting the TdF on equal footing, one not having to do a thing and the other having to scramble to get equal quality equipment".
"A couple days later LA ended up using the same wheel in the TTT, but AC did not. Though, during the Annecy TT, both cyclists ended up using the same wheel, although Lance used a different logo."
"To those in the know we will say that all Astana riders, except Lance Armstrong, had access to and actually used the Lightweight 240 brand, while the Texan was given the more advanced and newer version, the Lightweight 190, with ceramic bearings, approximately 15% lighter and 30% more rigid due to the way the carbon fibers were laid out (in a criss-cross pattern). Only AC's mechanic, who is not the best mechanic in the world but is one of the best, could have noticed such a small difference like that. But he did."
And the rest is history.
