Choosing bicycle drivetrain brakes can feel like two problems at once: are you updating the parts that move the chain, or the parts that slow the wheels? The four options here cover both sides, from a road groupset with a brake lever to a hydraulic mountain bike disc brake set. The decision gets easier when you sort them by what you already have and what you want to change.
Quick Take
For a road-specific refresh, the Shimano 105 R7000 groupset bundles the front derailleur, rear derailleur, and brake lever. For a rear drivetrain refresh, the Shimano Deore M4100 groupset covers the rear shifting path. If stopping power is the priority, the Shimano SLX disc brake set fills that role. If you need a simple all-in-one cable replacement, the Mountain Bike V Brake Set includes calipers, levers, cables, and mounting hardware.

Closer Look
Shimano 105 R7000 2 x 11 Speed 3pcs Groupset Front Rear Derailleur Brake Lever
This 2 x 11-speed groupset is a single-package answer for a road bike: you get the front derailleur, rear derailleur, and brake lever from the R7000 line, with a medium-cage (GS) rear derailleur and a brazed-on front mount. Choose it if the priority is refreshing the shifting and lever setup rather than buying calipers. The trade-off is that the set is focused on the drivetrain and the lever, so it is not a complete brake system, and the parts are OEM units not packaged in retail boxes.
Shimano Deore Groupset M4100 Shifter Cassette Sprocket M4120 Rear Derailleur
This Deore M4100 package is built around the rear of the drivetrain: a 10-speed shifter, M4120 rear derailleur, 11-42T cassette, and KMC X10 chain. The 116-link chain and 11-42T spacing give a clear gearing window for a 10-speed setup, and the shifter is part of the Deore line. It makes sense if you want to refresh the rear shifting path in one go. The limitation is the scope: the included parts are the shifter, rear derailleur, cassette, and chain, so front derailleur and braking are outside this set, and the 11-42T cassette defines the gear range you're working with.
Shimano SLX BR-M7120 BL-M7100 4-Piston Ice-Tech Hydraulic Brake Front/Rear/ Set
Shimano SLX brings four-piston hydraulic braking to a mountain bike setup. The BR-M7120 calipers pair with BL-M7100 levers, with 900 mm front and 1600 mm rear brake hoses, one-way bleeding, and reach adjustment without tools. The kit is listed as front and rear in a left/right configuration, and no rotor is included. Choose it if you're building or upgrading a bike with postmount caliper mounts. You'll need to add rotors separately, and the postmount design targets mountain bike frames rather than road or hybrid frames.
Mountain Bike V Brake Set Front and Rear MTB Hybrid Callipers Cables Lever Kit
This V-brake kit is a complete mechanical package: front and rear calipers, brake levers, two cables, brake boots, noodles, washers, and screws. It's listed as compatible with mountain, hybrid, BMX, and cyclocross-style bikes. The material is alloy and plastic, with cable actuation running from the levers to the calipers. Choose it if you want a straightforward refresh without hydraulic lines. The limitation is that it is a cable-actuated set, not a hydraulic brake set, and it uses V-brake-style calipers.
Final Recommendation
If you're servicing a road bike and want shifting plus a brake lever in the same purchase, start with the Shimano 105 R7000 groupset. If hydraulic stopping is the main goal for a mountain bike, plan around the Shimano SLX set. If your focus is the rear of the drivetrain, the Shimano Deore M4100 package gathers the key parts in one box. And if you need to replace worn V-brakes with cables and levers included, the Mountain Bike V Brake Set handles that all at once.
