Choosing front-and-rear brake parts is also a choice between two ways to stop. A cable V-brake kit sits at the low end of the price spread, while a Shimano hydraulic disc brake set sits at the high end. Both count as bicycle drivetrain brakes, but they are built for different bikes and different riding styles. The two V-brake kits in this comparison are front-and-rear rim brake sets. The two hydraulic sets are front-and-rear mountain bike disc brake pairs. The SLX set specifically ships without rotors, so the total project price depends on the rotors you pair with it. This guide compares the four sets so you can decide which one fits your bike and the way you ride.
Quick take
The group splits into two cable V-brake kits and two Shimano hydraulic disc brake kits. The Shimano SLX BR-M7120 / BL-M7100 is the most expensive option. The Shimano Deore BR-M6120 / BL-M6100 is the other Shimano hydraulic set. The Mountain Bike Linear V-Brake Set is the rim-brake refresh option. The Mountain Bike V Brake Set is the full kit.

Decision matrix
- Trail riders who want a 4-piston hydraulic caliper with postmount attachment: Shimano SLX BR-M7120 / BL-M7100. It also adds one-way bleeding and tool-free reach adjustment.
- Riders who want a 4-piston hydraulic layout for less: Shimano Deore BR-M6120 / BL-M6100. It offers a shorter free stroke and inboard hose routing.
- Riders refreshing rim brakes on a mountain or hybrid bike: Mountain Bike Linear V-Brake Set. Spring tension adjustment and a 110mm arch with 70mm pads are the fit details that matter.
- Riders who need a complete cable replacement: Mountain Bike V Brake Set with callipers, cables, and levers. It includes front and rear arms plus cables, boots, noodles, washers, and screws, and it is listed for caliper, V, and U brake styles.
Product notes
Shimano SLX BR-M7120 / BL-M7100
This SLX set combines a 4-piston Ice-Tech caliper with postmount brake mounting and a one-way bleeding system. The 2-finger lever has tool-free reach adjustment, and the brake hoses are 900mm front and 1600mm rear, so they can be shortened during installation. I-Spec EV compatibility lets you mount the shift lever directly to the brake lever for a cleaner cockpit. The biggest limitation is that it ships without rotors; Shimano SM-RT70 Centerlock rotors in 140, 160, 180, and 203mm are available separately. At $219.99, it is also the most expensive set in this comparison, and it is designed for a mountain bike with postmount brake tabs.
Mountain Bike Linear V-Brake Set - Front & Rear
This linear V-brake set is a practical rim-brake refresh for a mountain bike. It comes as a front-and-rear pair and includes the noodles, boots, and screws needed for installation. The aluminum arms help keep the brakes light, and the spring tension is adjustable so you can tune the brake feel. The set uses a 110mm arch and 70mm brake pads, and it is listed as compatible with the Chooee Mountain Bike. The limitation is that this is a rim-brake setup, so it stops the wheel by squeezing the rim rather than using a disc rotor. At $23.39, it is priced above the other V-brake kit in this comparison, though still well below the hydraulic sets.
Mountain Bike V Brake Set Front and Rear MTB Hybrid Callipers Cables Lever Kit
The Mountain Bike V Brake Set is the complete front-and-rear brake package at the bottom of this price range. It includes front and rear V-brake arms, two cables, brake boots, noodles, washers, and screws, so it works as a full cable-operated replacement kit. The housing uses alloy and plastic, with resistance to cold, heat, and oxidation, and the brake type is listed for caliper, V, and U brake styles. Its compatibility list covers mountain bikes, BMX bikes, cyclocross bikes, and hybrid bikes. The main limitation is that this is a cable setup rather than a hydraulic disc brake, and the mix of alloy and plastic parts is built for replacement duty. At $18.99, it is the lowest price in this group.
Shimano Deore BR-M6120 / BL-M6100
The Deore set is the second Shimano hydraulic option in the group, and it uses a 4-piston caliper. It is built around quick brake engagement with a shorter free stroke, and the optimized lever axle position and inboard hose routing make for a clean brake setup. Front and rear hose lengths are 850mm and 1550mm, so it arrives as a front-and-rear pair for a mountain bike. The limitation is price: at $169.88, it is the second-most expensive set here, and the hydraulic disc brake system costs more than the V-brake kits in this comparison. It is part of the Shimano Deore M6100 series and works with Shimano ICE brake pads.
Final recommendation by use case
- For trail riding with steep or sustained descents, choose the Shimano SLX BR-M7120 / BL-M7100 set.
- For a Shimano hydraulic alternative, choose the Shimano Deore BR-M6120 / BL-M6100 set.
- For a direct rim-brake refresh on a mountain or hybrid bike, choose the Mountain Bike Linear V-Brake Set.
- For a full V-brake kit, choose the Mountain Bike V Brake Set.
