SRAM GX Eagle Single Click Trigger Shifter - E-MTB, 12-Speed, Lunar The GX Eagle Single Click shifter is built for the demands of e-mountain bikes. It limits the pull lever to a single shift per push, so you can&';t dump several gears at once under motor torque - the main cause of premature chain wear and snapped chains on e-bikes. Release still shifts one gear at a time with crisp, consistent X-Actuation. E-MTB specific: one gear per pull to protect chain and cassette under motor load Aluminum trigger lever for a positive, solid feel X-Actuation for sharp, consistent shifting across the full 12-speed Eagle range Zero Loss engagement - the cable moves the instant you push the lever Includes discrete handlebar clamp; MatchMaker X compatible Lunar finish matches the GX Eagle colorway and any Eagle cassette and chain color Includes 2200 mm shift cable Compatibility: SRAM 12-speed Eagle mechanical rear derailleurs (X-Actuation). Not compatible with T-Type / Transmission derailleurs. Right-hand, rear shifter. SRAM part # 00.7018.432.000.
