The Shimano BR-5700 [paid link] brake calipers are part of the 105 5700 series—a workhorse group praised for its reliability and performance-to-value ratio. However, in a market filled with incremental upgrades and evolving technologies, many riders find themselves comparing the BR-5700 [paid link] to newer models like the Shimano R7000. Understanding the specific differences between these two caliper models is critical when upgrading, maintaining, or tuning a road bike. This article examines all key aspects—from installation and mechanical design to performance and compatibility—to help you make an informed decision.
Design Philosophy and Mechanical Layout
The BR-5700 [paid link] uses a traditional dual-pivot design that was standard in mid-tier Shimano groupsets before the widespread adoption of more refined caliper geometries. It features a symmetrical arm design that prioritizes stable modulation and strong braking force.
In contrast, the R7000—part of Shimano’s updated 105 lineup—takes cues from the Dura-Ace R9100 series. Its caliper arms are more compact and incorporate a sleeker, more aerodynamic profile. Mechanically, the R7000 benefits from Shimano’s newer symmetrical dual-pivot architecture, which delivers smoother cable pull and enhanced brake lever feel.
For riders sensitive to brake feel, especially during aggressive descents, the R7000 provides a more consistent and progressive bite point than the older BR-5700.
Installation and Adjustability
The BR-5700 calipers mount using a standard recessed bolt-through-the-fork design, compatible with both traditional and newer frame standards. Installation is straightforward, with a barrel adjuster for cable tension and a centering screw for lateral alignment.
The R7000, while retaining the same mounting system, features an updated pivot design that improves alignment accuracy. The built-in pad angle adjustment in R7000 allows for finer tuning of pad-to-rim interface, making setup more forgiving for riders or mechanics working with slightly out-of-true rims.
While both models install similarly, the R7000’s refined adjustment mechanisms simplify the tuning process, reducing time spent on pad positioning and cable tension optimization.
Braking Performance in Real-World Conditions
Under dry conditions, both the BR-5700 and R7000 offer excellent stopping power when paired with compatible Shimano brake levers. However, differences emerge in wet or mixed terrain scenarios.
- BR-5700 Performance: Offers reliable but sometimes inconsistent braking in rain or mud due to its older arm geometry and less rigid caliper body. Pad contact timing can vary slightly between left and right arms if not perfectly centered.
- R7000 Performance: Enhanced rigidity and refined mechanics yield better modulation in all-weather conditions. The symmetrical dual-pivot design ensures both pads engage the rim more uniformly, providing greater control on technical descents.
In terms of performance, the R7000 clearly surpasses the BR-5700 in modulation, bite feel, and all-weather consistency.
Brake Pad and Rim Compatibility
The BR-5700 uses Shimano’s standard R55C pads, compatible with alloy rims. While effective, these pads can wear quickly under aggressive use or in wet climates.
The R7000 uses the same Shimano-standard cartridge design, but often ships with R55C4 pads that offer improved durability and better wet weather performance. Because both models use Shimano’s standardized cartridge system, pad interchangeability is guaranteed. However, the R7000 caliper’s improved angle adjustment allows for more precise pad-to-rim contact, which can extend pad life and improve brake response.
Weight and Aesthetics
- BR-5700: Approximately 330 grams per pair, depending on hardware and finish. Its profile is more utilitarian and boxy, reflecting the design trends of its era.
- R7000: Slightly lighter at approximately 325 grams, and features a more modern, aerodynamic profile with a glossy finish that complements newer frame designs.
For weight-conscious riders or those looking to maintain a clean, modern aesthetic, the R7000 offers subtle advantages.
Customization and Upgrade Path
The BR-5700 can be upgraded modestly by using premium brake pads, replacing the stock cable housing with low-friction options, and ensuring rim surfaces are clean and decontaminated. However, mechanical limitations in its design restrict braking improvements beyond these basic modifications.
With the R7000, riders benefit from broader compatibility with newer Shimano STI levers, integrated cable routing designs, and improved performance from high-end cables and advanced rim coatings. Its braking curve also matches more closely with contemporary STI lever ergonomics, enhancing feel at the hoods and drops.
Compatibility With Drivetrain and Levers
- BR-5700: Best paired with Shimano 5700 series shifters and levers. Cross-compatibility with other Shimano 10-speed levers is possible, but performance may suffer due to mismatched cable pull ratios.
- R7000: Fully optimized for Shimano’s 11-speed systems, but maintains backward compatibility with older STI levers. However, optimal performance is achieved when matched with R7000 or R8000 series levers due to consistent cable pull dynamics.
This makes the R7000 a more versatile option for riders upgrading from 10-speed to 11-speed setups.
Verdict: Which Should You Choose?
Choose BR-5700 if:
- You’re maintaining an existing 10-speed Shimano 105 groupset.
- Budget constraints are a priority.
- You prefer to maintain legacy components without overhauling your system.
Choose R7000 if:
- You want better modulation and brake feel.
- You’re upgrading to an 11-speed system or modern frameset.
- You ride in variable weather conditions and need more predictable braking.
While the BR-5700 remains a solid performer, the R7000 offers substantial improvements in ergonomics, performance, and maintenance simplicity, making it the better long-term investment.
