Dura Ace Lite
New for 2010, Trek Bikes is offering “Dura Ace Lite” on their Project One bikes. Now, this is not an official group from Shimano, but a price saving package from Trek. It’s basically the 6700 package with the crank and derailleurs from the 7900 group.
In short, if you want to save weight and money, go for Dura Ace Lite—you save 134 grams over Ultegra, and pay only $630. In comparison, the full Dura Ace group set costs almost $1000 more ($1564.50) to save only an extra 115 grams. (249 grams total over Ultegra)
