The Shimano CS-5700 [paid link] is a trusted 10-speed road cassette from the 105 series, known for its solid performance and wide compatibility. However, proper installation is critical. Even small missteps during the setup can lead to poor shifting performance, unnecessary drivetrain wear, or even component failure. In this guide, we’ll explore the most common CS-5700 [paid link] cassette installation mistakes and how to prevent them, ensuring your drivetrain runs flawlessly from the first pedal stroke.
Improper Cassette Alignment on Freehub Body
One of the most frequent installation errors with the CS-5700 [paid link] cassette is misaligning the sprockets on the freehub body. Each sprocket and spacer must align with the grooves on the freehub shell, especially the narrow spline which ensures correct orientation.
When a sprocket is forced onto the freehub in the wrong position, it causes improper spacing. This disrupts indexed shifting and increases friction across the cassette. Always ensure that each sprocket slides easily onto the freehub, aligning the narrow spline to the corresponding notch.
Incorrect Use or Omission of Spacers
The CS-5700 cassette is designed for 10-speed systems, and it typically requires a 1.85mm spacer when mounted on 11-speed freehub bodies. Neglecting to add this spacer can result in excessive lateral play, which compromises both gear alignment and shifting precision.
Additionally, adding extra or incompatible spacers can tighten the cassette improperly, potentially causing uneven sprocket loading. Always refer to Shimano’s compatibility chart and ensure you’re using only the correct spacers for your hub system.
Under or Over-Tightening the Lockring
Using incorrect torque on the lockring during installation can lead to performance issues or even component damage. The CS-5700 cassette lockring requires a specific torque—usually 40 Nm—for proper fitment.
Under-tightening may allow the cassette to loosen during riding, creating clunky shifts and drivetrain noise. Over-tightening, on the other hand, risks damaging the threads of the freehub or the lockring itself. Always use a torque wrench [paid link] with a cassette lockring tool [paid link] to achieve precise torque specifications.
Dirty or Dry Freehub Splines
Installing the cassette onto a dry, dirty, or corroded freehub can cause the sprockets to bind or seize under load. This also increases the likelihood of metal-on-metal wear, especially under torque.
Before installing the CS-5700 cassette, clean the freehub splines thoroughly and apply a light coat of grease. This not only facilitates smooth cassette installation but also prevents seizing and corrosion over time.
Using Worn Components During Installation
It’s critical to inspect your chain and chainrings before installing a new CS-5700 cassette. If the chain is elongated or the chainrings are worn, they will not mesh correctly with the new cassette, resulting in premature wear and subpar shifting.
The CS-5700 works best with a fresh or lightly used chain that matches the cassette’s wear level [paid link]. Shimano recommends replacing the chain every 1,500–2,000 miles under normal use to prevent excessive cassette wear.
Neglecting Indexing Adjustment Post-Installation
Even when the cassette is installed correctly, failing to adjust the derailleur indexing can undermine performance. The CS-5700’s gear spacing is designed specifically for Shimano 10-speed systems, and the rear derailleur must be adjusted accordingly.
A misaligned derailleur cable tension or limit screw setting will result in sluggish or inaccurate shifts. After installing the cassette, shift through all gears and fine-tune the barrel adjuster to ensure clean, crisp transitions between cogs.
Mixing Incompatible Cassette Components
Some users attempt to mix sprockets from different Shimano groupsets or use aftermarket lockrings with the CS-5700 cassette. While some combinations might physically fit, they can lead to inconsistent spacing or compromise tooth profiling, which degrades shifting quality.
To maintain factory-level [paid link] performance, install the CS-5700 using only OEM components in the correct configuration. Avoid interchanging cogs between models or using parts from other drivetrains unless Shimano explicitly supports compatibility.
Failing to Inspect for Freehub Wear
An often-overlooked issue is freehub wear—especially on aluminum-bodied hubs where cassette splines can bite into the material. A worn or damaged freehub will not hold the sprockets in proper alignment, even if everything is torqued correctly.
Before installing your CS-5700 cassette, inspect the freehub splines for deep notches or deformation. Replace or service the freehub body as necessary to ensure a stable mounting surface.
Skipping Test Rides After Installation
Riders often overlook the importance of a post-installation test ride. Skipping this step can allow undetected shifting issues or misalignment to persist, potentially leading to long-term drivetrain problems.
Always test ride the bike after installing the CS-5700 cassette. Shift through all gears under load and listen for noise, hesitation, or skipping. This helps identify issues early when they’re still easy to fix.
Conclusion
Correct installation of the Shimano CS-5700 cassette is foundational to reliable drivetrain performance. By avoiding common mistakes like spacer misplacement, improper torque, and misaligned sprockets, you can ensure smoother shifts, longer component life, and fewer mid-ride headaches.
Whether you’re installing the cassette yourself or working with a professional mechanic, following these best practices will keep your bike operating at peak performance. For riders looking to dive deeper, consider regularly inspecting your drivetrain and pairing your cassette with compatible, well-maintained components.
