The Shimano FH-5800 [paid link] hub, part of the 105 series, is designed for road cyclists seeking reliable and efficient performance. Proper installation, adjustment, and maintenance are crucial to ensuring smooth rolling and long-lasting durability.

In this guide, we will walk you through the step-by-step process of setting up your Shimano FH-5800 [paid link] hub, troubleshooting common issues, and maintaining it for optimal performance.

Tools Required

  • Cone wrenches (13mm and 15mm)
  • Adjustable wrench
  • Hex keys [paid link] (5mm and 10mm)
  • Grease (Shimano Dura-Ace or similar)
  • Cleaning brush and degreaser
  • Rag or paper towels
  • Torque wrench [paid link] (recommended)
  • Spoke key (if adjusting spoke tension)

Step 1: Installing the Shimano FH-5800 Hub

1.1 Preparing the Wheel and Hub

Before installation, make sure your hub and wheel components are clean and free from debris. Inspect the hub shell, bearings, and freehub for any visible damage or wear.

1.2 Mounting the Hub into the Wheel

  1. Align the FH-5800 [paid link] hub with the wheel rim, ensuring that the spoke holes match the lacing pattern.
  2. Lace the spokes correctly, following Shimano’s recommended lacing pattern for optimal wheel strength.
  3. Use a spoke tension meter to ensure even tension across all spokes.

1.3 Installing the Cassette

  1. Apply a thin layer of grease to the freehub body splines to prevent corrosion.
  2. Slide the cassette onto the freehub, ensuring proper alignment.
  3. Secure the cassette lockring using a cassette tool and tighten to 40Nm using a torque wrench [paid link].

1.4 Attaching the Quick Release Skewer

  1. Insert the quick-release skewer through the hub axle.
  2. Tighten the nut until the skewer provides firm resistance when closing.
  3. Ensure the wheel is centered in the dropouts before final tightening.

Step 2: Adjusting the Shimano FH-5800 Hub

2.1 Checking Hub Bearing Preload

  1. Spin the wheel and check for any lateral play or roughness in the bearings.
  2. If the hub feels loose or rough, adjustment is necessary.

2.2 Adjusting the Cone and Locknut

  1. Use cone wrenches to loosen the locknut while holding the axle in place.
  2. Adjust the cone by tightening or loosening it in small increments.
  3. Aim for a setting where there is no lateral play, but the wheel spins freely.
  4. Once adjusted, hold the cone in place and tighten the locknut securely.

2.3 Ensuring Proper Axle Alignment

  1. Check that the axle is centered within the dropouts.
  2. If misaligned, loosen the quick-release skewer, adjust the position, and retighten.

Step 3: Maintaining the Shimano FH-5800 Hub

3.1 Regular Cleaning and Lubrication

  • Wipe down the hub shell with a clean rag after every ride.
  • Apply fresh grease to the bearings every 3,000-5,000 km to prevent wear.

3.2 Servicing the Bearings

  1. Remove the quick-release skewer and axle.
  2. Take out the bearings carefully using tweezers.
  3. Clean the bearing races and apply new grease.
  4. Reinstall the bearings and reassemble the hub.

3.3 Checking for Wear and Tear

  • Inspect the freehub for excessive play or roughness.
  • Replace worn-out bearings or a faulty freehub body if necessary.

3.4 Preventing Water and Dirt Ingress

  • Use waterproof grease on external seals.
  • Avoid power-washing the hub directly to prevent contamination.

Common Issues and Troubleshooting

4.1 Hub Feels Rough or Does Not Spin Freely

Cause: Over-tightened bearings or contamination inside the hub.
Fix: Re-adjust the cone tension and clean/re-grease the bearings.

4.2 Freehub Slipping or Skipping Under Load

Cause: Worn pawls or insufficient lubrication.
Fix: Disassemble the freehub, clean the internals, and apply light oil.

4.3 Unusual Clicking or Grinding Noises

Cause: Loose locknut, dirt buildup, or worn bearings.
Fix: Tighten all components and inspect for debris inside the hub.
