Sram X7 2/3 Speed Front Trigger Shifter 2012
SRAM adds a "2-by" option to their line up of front shifters. The X.7 series shares much of the same DNA of X.9 and X.0 level components and is great blend of performance and affordability.
The X.7 trigger shifters feature SRAM's proven 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result is the easiest index shifting system to set up and stays that way.
Another great benefit of the X.7 line up is that it is MatchMaker compatible. With the MatchMaker you can save weight and clutter on the handlebar. This system holds Avid levers, a number of SRAM triggers and the RockShox PushLoc control- all with one tidy, light clamp.
