When you're building or upgrading a bike, the brake levers and shifters are the parts you touch most, and they need to match the rest of the drivetrain. Bicycle drivetrain brakes cover everything from a single mountain-bike trigger shifter to a full road groupset with derailleurs and levers. The four options here span a wide price range, so the real decision is less about brand loyalty and more about what your build actually needs: a complete gruppo, a dedicated lever set, or the one missing shifter to finish an existing drivetrain.
Quick Take
If you're completing a 12-speed SRAM Eagle mountain drivetrain, the GX Eagle shifter is the least expensive part in this group. If you're working on a SRAM road bike, the Rival DoubleTap lever set supplies both brake-shift levers. If you want a new, never-installed 2x11 road groupset with derailleurs and levers, the Shimano 105 R7000 three-piece set is the balanced mid-price pick. If you want the most complete Campagnolo package, the Centaur build kit includes 175mm crank arms, 53/39 chainrings, and a 12-27 cassette, though it will cost you the most in this group.
Price Comparison
| Option | Listed Price | Price Position |
|---|---|---|
| SRAM GX Eagle Shifter - Lunar | USD 41.00 | |
| SRAM Rival Carbon DoubleTap Lever Set | USD 149.00 | |
| Shimano 105 R7000 Three-Piece Groupset | USD 179.88 | |
| Campagnolo Centaur Build Kit | USD 350.96 |
How to Choose
- For a mountain-bike shifter replacement: The SRAM GX Eagle is the only trigger shifter in this comparison.
- For a dedicated road lever set: The SRAM Rival is the obvious choice when you need a left-and-right brake/shift lever set.
- For a new road groupset start: The Shimano 105 R7000 includes the two derailleurs and brake lever in one box.
- For a Campagnolo road build: The Centaur kit is the broadest package in this group.
The Four Options
SRAM Rival 2x10 Speed Carbon DoubleTap Brake Shift Lever Set Road Bike
If you already have a SRAM Exact Actuation road drivetrain, this Rival set gives you the controls to match. The left lever runs the front derailleur for a 2x setup, the right lever runs the rear derailleur, and the DoubleTap shifting is built around SRAM's road action. The carbon brake lever material is a clear standout, and the set includes both the left and right levers. The limitation is condition: this is a used set, so you're buying components that have seen handlebar time rather than fresh-in-box parts. At $149, it is a complete lever pair rather than a single piece, which makes it a practical replacement for a SRAM road bike.
Campagnolo Centaur Black 10-speed Road Bike Groupset 175mm 53/39 12-27 Build Kit
This Centaur kit is the most complete option in the group because it is a build kit with 175mm crank arms, 53/39 chainrings, and a 12-27 cassette, along with the front and rear derailleurs. It is listed as compatible with cyclocross, gravel, and road bikes, and the front derailleur uses a 34.9mm clamp mount. The chain, cassette, and chainrings show minimal wear, but the condition is still used. At $350.96, it is the most expensive option here, and it is Campagnolo-specific, so it only makes sense when the rest of your bike is set up for Campagnolo.
SRAM GX Eagle 12 Speed Shifter and Discrete Clamp Lunar Mountain Bike - NEW OEM
If your Eagle drivetrain is missing its right shifter, this GX Eagle piece is the direct fix. It is a 12-speed trigger shifter in a Lunar finish, brand new and never mounted, and part of an OEM batch, so it does not come in a retail box. The package includes the discrete clamp with bolt, two ferrules, a shift cable, and a cable end. The limitation is scope: it is only a right shifter, not a brake lever or a groupset. If your bike needs brake controls or a front shifter, this will not cover those. At $41, it is the least expensive option here.
Shimano 105 R7000 2 x 11 Speed 3pcs Groupset Front Rear Derailleur Brake Lever
This three-piece groupset is a solid middle ground for a 2x11 road bike. It includes the front derailleur, rear derailleur, and brake lever, with the rear derailleur in a medium cage (GS) version. The front derailleur uses a brazed-on mount, so the frame needs a braze-on tab. The condition is new other: these are OEM Shimano parts, never installed on a bike, but not in retail packaging. That means you get the mechanical parts without the box. The set is not a full groupset, so you will still need to pair it with a crank, cassette, chain, and brakes. If you are collecting parts for a Shimano 105 road build, this is the set that packages both derailleurs with a brake lever.
Final Recommendation by Use Case
- For the least expensive Eagle mountain-bike fix: Choose the SRAM GX Eagle shifter. It includes the clamp, cable, and ferrules in the box.
- For a SRAM road lever pair: Choose the SRAM Rival DoubleTap set.
- For a new road groupset core: Choose the Shimano 105 R7000 set to get the derailleurs and brake lever together.
- For a Campagnolo road build: Choose the Campagnolo Centaur build kit if your bike is already set up for Campagnolo.
