The Shimano CS-5700 [paid link] cassette, a 10-speed road cassette from the 105 series, is a widely used and dependable component in many mid-range road bikes. Despite its reliability, improper setup is a common source of performance issues like skipping gears, noisy shifting, or drivetrain inefficiency. This guide will help riders diagnose and resolve CS-5700 [paid link] setup issues to restore optimal performance.
Understanding the CS-5700 Cassette Design
The Shimano CS-5700 [paid link] is a Hyperglide (HG) cassette featuring precisely shaped ramps and tooth profiles. It’s engineered for smooth, fast gear transitions under load. The cassette is compatible with Shimano 10-speed freehub bodies and pairs best with Shimano 10-speed chains and drivetrains.
Due to its precise engineering, even minor installation errors or compatibility oversights can lead to degraded performance. Understanding the cassette’s structure and function is critical before attempting setup corrections.
Common Setup Problems and Their Root Causes
Improper setup of the CS-5700 can be traced to a few typical mistakes. Recognizing these is the first step in fixing the issue:
1. Incomplete or Incorrect Installation
Even a slightly misaligned lockring or missing spacer can cause the cassette to shift poorly. A common mistake is omitting the 1.85mm spacer required when fitting the CS-5700 on a Shimano 11-speed freehub body. Without this spacer, the cassette cogs don’t align correctly, resulting in poor indexing.
2. Incompatible Chain or Derailleur
The CS-5700 is designed for Shimano 10-speed systems. Using it with an 11-speed chain or non-compatible derailleur (such as a SRAM Exact Actuation derailleur) can cause shifting hesitation or excessive noise. Chain width mismatch disrupts the flow across the cog ramps.
3. Misadjusted Rear Derailleur
If the B-tension screw is not correctly set, or the high/low limit screws restrict derailleur travel, the derailleur won’t guide the chain accurately. This creates problems such as ghost shifting, inability to reach all gears, or chain rub on adjacent cogs.
4. Worn or Dirty Components
Dirty, dry, or stretched chains paired with a new CS-5700 cassette will result in poor engagement and slipping. Similarly, using a worn cassette with a new chain can accelerate wear and impair shifting. Proper drivetrain hygiene is vital for reliable function.
5. Cable Tension Issues
Incorrect cable tension—either too slack or too tight—prevents the derailleur from indexing precisely across the 10 cogs. Modern Shimano setups are especially sensitive to cable tension, and even slight misadjustments can throw off performance.
Diagnostic Process for Identifying Setup Errors
Riders should perform a methodical check to identify which issue is causing poor performance in their CS-5700 setup:
- Visual Inspection: Check cassette tightness, verify presence of spacers, and inspect chainline.
- Hand Pedal Testing: Shift through all gears while pedaling on a bike stand [paid link] to identify sticking points or skips.
- Component Compatibility Review: Confirm that the chain, derailleur, and shifters are all 10-speed Shimano compatible.
- Cable Condition Check: Examine housing for kinks or fraying and test smooth cable movement.
- B-Tension and Limit Screw Assessment: Ensure rear derailleur clears the largest cog and doesn’t overshoot on the smallest.
Corrective Actions to Fix CS-5700 Cassette Setup Issues
Once issues are identified, resolving them usually requires one or more of the following interventions:
Reinstallation with Proper Spacer Use
Remove the cassette and reinstall using a torque wrench [paid link], ensuring the correct torque (typically 40 Nm) and spacer setup based on the freehub body. A 1.85mm spacer is essential for use on 11-speed road freehubs.
Chain and Derailleur Alignment
Replace worn chains and check that the derailleur hanger is straight. Misaligned hangers skew the derailleur path, making accurate shifts impossible. Alignment tools or professional servicing may be required.
Derailleur Adjustment
Fine-tune cable tension using barrel adjusters until shifting is smooth and reliable across all gears. Reset limit screws to prevent over-travel or restricted movement. Adjust B-tension to set the correct gap between the guide pulley and the largest cog.
Drivetrain Cleaning and Lubrication
Degrease and clean the cassette, chain, and chainrings. Apply fresh, suitable chain lube to reduce friction and promote clean engagement. Dirty components mimic mechanical issues and can mislead diagnostics.
Preventative Tips for Future Setup Accuracy
To avoid repeat issues with the CS-5700 cassette setup, follow these best practices:
- Use only Shimano or Shimano-compatible 10-speed components.
- Always inspect and replace drivetrain components as a group (cassette, chain, chainrings) when wear is significant.
- Maintain proper chain tension and check cable health every few months.
- Use a torque wrench [paid link] when installing the lockring to avoid over-tightening or under-tightening.
- Regularly inspect for cassette body wear, which can affect cog alignment.
Conclusion
An improperly set up Shimano CS-5700 cassette can compromise the entire riding experience. Fortunately, most setup errors are easy to identify and correct with a methodical approach. From ensuring spacer placement to adjusting derailleur tension, small tweaks can yield significant improvements. By understanding the nuances of CS-5700 installation and performance, riders can keep their drivetrain running smoothly and extend the life of their components.
