The Sram X9 Trigger Shifter is a fantastic addition to any mountain bike that is looking for lightweight components that are slick to use and durable enough to handle the off road trails. The X9 shifter has a new smaller design for the new year for more compact shifting and uses the same technology as the XX and X0 parts for dependable performance. The Sram gear shifter uses Impulse technology and is Matchmaker compatible to save on weight for better performance and less space taken up on the bars. The X9 has been made with ZeroLoss technology means that there is zero loss of movement and gives precise and instant gear changing which is ideal for riders that find a laggy gear shift can throw off your game. The Sram gear shifter is designed for 10-speed chainsets and uses Exact Actuation technology that gives easier index gear shifting.

EA helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way. Matchmaker Compatible Save weight and clutter on the bar with MatchMaker. This system holds Avid® levers, a number of SRAM® triggers and RockShox PushLoc controls – all with one tidy, light clamp. ZeroLoss ZeroLoss simply means, well, zero loss—when you push on the lever, for an upshift or down shift, the cable is engaged instantly—zero loss of movement. There is no middle-ground where you’re waiting for the shift to come. Gear changes are instant and precise.
