Shimano still offers their uber popular 7900 shifters for those wanting to stick with 10-speed. These 7900 STI dual control levers are now sold separately for front and rear. That is great news for those replacing a damaged lever because you don't have to buy both. If you are setting up a 10-speed bike you will of course want to make sure you order one front and one rear.
Shimano's Dura-Ace 7900 STI levers offer a refined, asymmetric contours that offer a true anatomic/ergonomic shape very friendly to the hands. Hidden shifting cables add hand positions and completely clean up the cable routing. Semi-exposed internals with uni-directional carbon shifting blades help reduce the weight 40 grams over previous Dura-Ace shifters. Shifting stroke for the rear derailleur has been reduced by 20% for quicker shifts and a built in reach adjuster allows for fine tuning the fit for riders with smaller hands.
For 10-speed mechanical systems only.
