Quick take
If you're shopping for bicycle drivetrain brakes, the real decision is how much of SRAM's Eagle ecosystem to bring home. Do you just need a rear trigger shifter for a modern 1x mountain bike, or do you want a complete AXS groupset with cassette, cranks, bottom bracket, battery and charger? The options here span from a $32.95 no-clamp rear shifter to a $375 full AXS build. In between are a clamp-and-cable-ready shifter and a triple-chainring trigger set for older mountain bikes.
The least expensive path is the SRAM GX Eagle Trigger Shifter No Clamp (Lunar), which works with a compatible no-clamp setup. If you'd rather have the handlebar clamp and shift cable in the package, the SRAM GX Eagle Shifter + Discrete Clamp (Lunar) does that. For a frame-up 1x build, the SRAM GX Eagle AXS Drivetrain bundles the derailleur, controller, cassette, cranks, bottom bracket, battery and charger. And for a vintage hardtail, the Sram X0 trigger set is the straightforward pick.

Product notes
SRAM GX Eagle Shifter + Discrete Clamp (Lunar)
The SRAM GX Eagle Shifter with Discrete Clamp is the one to grab when you want a clean, complete rear shifter for a 12-speed Eagle drivetrain. It is listed as new OEM and has never been mounted, and it includes the discrete clamp, bolt, two ferrules, premium shift cable and cable end. That makes it a practical spare or replacement part when your existing shifter gives up. The main limitation is that it is an OEM part without a retail box, so the packaging is basic. It also is the right shifter only, which fits a 1x12 setup.
SRAM GX Eagle Trigger Shifter No Clamp (Lunar MatchMaker X)
If your handlebar setup already uses MatchMaker X, the SRAM GX Eagle Trigger Shifter No Clamp is a deliberately slim choice: it's the rear trigger shifter only, in a Lunar finish, with an aluminum lever and an updated internal mechanism for crisp shifts. Because there is no clamp, it keeps the bar area less cluttered and pairs directly with a compatible mounting system. The trade-off is that you need that MatchMaker X-style mounting point already in place; this version does not bring its own handlebar clamp. It's also a rear shifter only, so it won't cover front shifting for a multi-chainring setup.
SRAM GX Eagle AXS Wireless Drivetrain
The SRAM GX Eagle AXS Wireless Drivetrain is the whole package for someone starting a 1x mountain bike build or upgrading a frame that already has compatible parts. It includes the wireless derailleur, wireless controller with handlebar clamp, XG-1275 10-52T cassette, Truvativ Stylo DUB 170mm crankset with a 32T X-Sync 2 chainring, DUB threaded bottom bracket, AXS battery, and AXS charger. The kit is used and was removed from a mountain bike after regular use, so the used condition is the main limitation.
Sram X0 3x9 Trigger Shifter Set
For a vintage 3x9 mountain bike, the Sram X0 Trigger Shifter Set is the period-matched option. It gives you both front and rear trigger shifters, and the bar clamps are brand new and sized for a standard 22.2mm grip diameter. The shifters came off a bike after two seasons and were stored before being offered, so the rear shifter shows the most use, including a carbon fiber cover with clear-coat scuffs. The inside of the cover is not damaged, but the visible wear is worth knowing. This set works best for a 3x9 drivetrain restoration.
Final recommendation by use case
Here's the short version: If you want the lowest listed price and already have a compatible no-clamp mount, go with the SRAM GX Eagle Trigger Shifter No Clamp. If you prefer a shifter that arrives with a clamp and shift cable, the SRAM GX Eagle Shifter + Discrete Clamp (Lunar) is the more complete single-part kit. If a full AXS groupset is the goal, the SRAM GX Eagle AXS Drivetrain is the option that covers the whole build in one used package. If your bike is an older hardtail with a triple chainring setup, the Sram X0 Trigger Shifter Set is the direct match.
