SRAM X7 Rear 10-Speed Trigger Shifter 2013
The highly capable X7 trigger shifters bring high-end precision and reliability to 10-speed at an unbeatable price. Their precise shifting and race-bred technology will boost your confidence in all types of terrain, from your local trail to the most challenging backcountry singletrack.
I have this on my 1x10 and combined with the X9 rear derailleur, it shifts smoothly and fast through all the gears. Like that there is no "idiot window". Using only my thumb to shift leaves all my fingers to grip the bars for more stability and steering power.
