I kept feeling like "woah, deja vu" the whole time, and then I realized it's because the author repeats everything approximately 100 times. Examples:
"One fact worth knowing for triathletes, if a bike has current Shimano 10 Speed components and shift levers in the tips of the aerobars there is only one Shimano bar-end style shifter: the Shimano Dura-Ace SL-BS78 Bar End Shifter. This is the bar end shifter used with all Shimano kits; Shimano 105, Ultegra and Dura-Ace. The shifters are all the same Dura-Ace SL-BS78 shifter. This is the black vinyl tipped shift lever you see on every Shimano equipped triathlon bike with bar end shifters in the tips of the aerobars. Gray vinyl tipped shift levers denote the earlier 9 speed version.
So, every Shimano equipped triathlon bike regardless of derailleurs uses the same shifter, The Shimano Dura-Ace Sl-BS78 10 Speed Bar End Shifter. The quality of the shift you feel is delivered through the tactile interface between your hand and the shifter. Whether you are using a Shimano 105, Ultegra, Ultegra SL or Dura-Ace derailleur or a mix of those derailleurs you will be shifting with the same shifter."
"The Shimano Ultegra (short cage) rear derailleur is available in two versions: The bright silver RD-6600 and the new 2008 RD-6600-G in ice gray. The new 2008 RD-6600-G Ultegra SL version is exactly 4 grams lighter than the silver RD-6600 Ultegra “Classic” version. For your reference, three paper business cards weigh four grams. Because of this minimal weight difference the Shimano RD-6600-G Ultegra SL and Shimano RD-6600 Ultegra Classic rear derailleur can be considered equal on performance and 4 grams different in weight, the weight of three business cards. "
