New Shimano 105 is new for 2011 and incorporates many of the benefits that were originally developed for Dura-Ace 7900 series and integrated into Ultegra 6700 series. The new group is available in Sterling Silver for a classic road cosmetic or Lodestar Black for a more contemporary look. Overall, performance and durability is enhanced while the entire group manages to drop almost 30 grams from the prior generation.
