Choosing between a loose shifter, a brake-only set, and a complete groupset can feel like comparing apples and orange bike projects. The real question is what your bike is missing. This lineup ranges from single replacement parts to a nearly complete drivetrain package, so the decision comes down to the style of riding you do and the component standard your frame uses.

- For a rear 12-speed trigger: SRAM GX Eagle Rear Trigger
- For a full front-and-rear brake set: Front and Rear Brake Set
- For a complete road groupset: LTWOO R7 Road Groupset

Product notes
SRAM GX Eagle 12 Speed Shifter and Discrete Clamp Lunar Mountain Bike - NEW OEM
This right-side shifter is built for 12-speed Eagle drivetrains and includes a discrete clamp and shift cable. The condition is listed as new other, and the item is said to have never been mounted. At USD 41.00, it sits between the other Eagle shifter and the full groupset in price. It comes in Lunar and is positioned for mountain bike use with SRAM compatibility. The trigger shifter style is a standard for Eagle mountain bikes, and the included clamp means you do not need a separate mounting base. If you are adding a right-side shifter to a 1x12 setup, this is the more complete option. Keep in mind that it is specified as a right shifter, so it will not work as a front or left shifter.
SRAM GX Eagle Trigger Shifter Rear 12-Speed No Clamp Lunar MatchMaker X
This rear trigger shifter is priced at USD 32.95 and is marked as new. It is designed for 12-speed Eagle drivetrains and has a Lunar finish with an aluminum trigger lever. The no-clamp design means it needs a compatible mounting setup such as MatchMaker X rather than a standard bar clamp, so it suits riders who already have that mount on their bars. It is specified as a rear shifter, so it is not intended for front shifting. If you are running a 1x12 setup or have a matching left shifter already, this is the lower-priced way to add the right-side control. The aluminum lever is a notable feature at this price, and the finish matches the other Lunar SRAM parts in this lineup.
Mountain Bike V Brake Set Front and Rear MTB Hybrid Callipers Cables Lever Kit
This kit covers both front and rear brakes and is the lowest-priced item here at USD 18.49. It includes brake arms, cables, levers, and the hardware pieces mentioned in the product materials. It is marketed as a universal V-brake set and lists compatibility with mountain bikes, BMX bikes, cyclocross bikes, and hybrid bikes. The materials are aluminum alloy and plastic, with a black/silver finish. Because it is a front-and-rear set, it can replace both brakes in one purchase. The V-brake style is suited for frames with V-brake studs; if you have that type of frame, this is a straightforward option. The universal positioning means it is not tied to a single bike model, which is worth keeping in mind when matching it to your fork and stays.
LTWOO R7 2x10 Speed Road Bike Groupset Shifter Derailleurs 11-32T Cassette Chain
This is a complete 2x10 road groupset priced at USD 149.00. It bundles shift-brake levers, front and rear derailleurs, an 11-32T 10-speed cassette, and a 10-speed chain. Compatibility is listed for Shimano 4700 cable pull, and the brake levers work with rim brakes or mechanical disc brakes, not hydraulic systems. That makes it a fit for road and touring bikes with cable-actuated brakes. The black finish keeps a clean look, and the brake lever body is described as aluminum alloy. If you are building a road bike from a frame or replacing a worn 2x10 groupset, this package brings the main components together. The main limitation is that it is road-focused, with an 11-32T cassette that provides a range suited to road riding rather than mountain terrain.
Final recommendation
- For a 1x12 mountain bike drivetrain with the right bar mount, the SRAM GX Eagle Rear Trigger is the targeted part.
- For a right-side shifter ready to bolt on, the SRAM GX Eagle Right Shifter is the complete package.
- For a two-wheel brake replacement on a V-brake frame, the Front and Rear Brake Set covers front and rear.
- For a road bike build, the LTWOO R7 Road Groupset brings the core drivetrain components together.
