The SRAM SX Eagle Single Click Trigger shifter uses the same ergonomic design as SRAM's higher end shifters and carries over many of their features, including Zero Loss to provide instant and responsive shifting. The Single Click Version of the SX Eagle Shifter can only be shifted up the cassette one shift at a time, making it ideally suited for use on electric bikes to prevent too much stress being put through the drivetrain. The SX Eagle Trigger Shifter is compatible with all other SRAM Eagle groupsets, so you can mix and match to your hearts content! The aluminium and plastic construction is also lightweight yet highly durable, so unlike other areas, the trickle down technology effect does not come with a weight penalty. Smooth, accurate and highly durable, the SRAM SX Eagle Trigger Shifter offers excellent performance and is superb value for money.
