Sram X4 Trigger Gear Shifters Pair For MTB Mountain Bike ( 8 Speed / 3 Speed )
Designed for 24 speed (3x8) drivetrains, the 1:1 actuation ratio necessitates the use of compatible SRAM rear derailleurs, whilst the shifters are compatible with any front derailleur. 1:1 actuation is superior by design.
