The Zipp 808 [paid link] wheelset is a high-performance aerodynamic option for road cyclists and triathletes looking to maximize speed and efficiency. Known for its deep-section carbon rims and advanced aerodynamics, the Zipp 808 [paid link] requires precise installation and regular maintenance to perform at its best.

This guide will cover everything from initial setup to ongoing maintenance, ensuring your wheels remain fast, stable, and durable.

Tools Required

Before you begin installing or maintaining your Zipp 808 [paid link] wheels, gather the following tools:

  • Tire levers (for mounting or removing tires)
  • Torque wrench [paid link] (for securing thru-axles or quick-release skewers)
  • Cassette lockring tool [paid link] (for installing or removing the cassette)
  • Pump or CO₂ inflator (for tire inflation)
  • Spoke wrench (for truing the wheel if necessary)
  • Bearing press [paid link] tool (for bearing maintenance)
  • Clean rags and isopropyl alcohol (for cleaning rim brake surfaces)

Installing the Zipp 808 Wheelset

1. Preparing the Wheels

Before installing, inspect the wheels for any shipping damage. Check the rim for cracks, ensure the hub bearings spin smoothly, and confirm the spokes are evenly tensioned.

2. Installing the Cassette

  • Place the cassette onto the freehub body, aligning the largest sprocket with the spline pattern.
  • Use the cassette lockring tool [paid link] to secure the lockring. Tighten to manufacturer specifications (typically 40Nm).

3. Mounting the Tires

  • If using clincher tires, install an inner tube and seat the tire properly. Inflate slightly before fully securing it.
  • If using tubeless tires, install tubeless valves and pour sealant into the tire before inflating. Make sure the bead is fully seated on the rim.

4. Attaching the Wheels to the Bike

  • For quick-release systems, insert the skewer through the hub, tighten the nut, and close the lever securely.
  • For thru-axle systems, slide the axle through the frame and hub, and tighten it using a torque wrench [paid link] (typically 10-12Nm).

5. Aligning Brakes and Gearing

  • If using rim brakes, ensure brake pads align with the braking surface and adjust the calipers.
  • If using disc brakes, check that the rotors do not rub against the brake pads.

Adjusting the Zipp 808 for Optimal Performance

1. Fine-Tuning Tire Pressure

Tire pressure significantly affects performance and comfort. Follow these general guidelines:

  • Clincher tires: 90–110 PSI (based on rider weight and conditions)
  • Tubeless tires: 80–100 PSI (for better grip and comfort)

2. Truing the Wheels

  • If you notice wobbling, place the bike on a repair stand and spin the wheel.
  • Use a spoke wrench to adjust tension slightly—clockwise tightens, counterclockwise loosens.
  • Avoid over-tightening to prevent stress fractures.

3. Hub and Bearing Adjustments

  • Spin the wheels; they should rotate smoothly without lateral movement.
  • If resistance is felt, check the hub preload adjustment.
  • If bearings feel rough, they may need replacement or additional lubrication.

Routine Maintenance for Longevity

1. Cleaning the Wheelset

  • Use a damp cloth and mild soap to clean the rims.
  • Avoid harsh chemicals that can damage carbon fiber.
  • Clean the braking surface regularly (for rim-brake models) to remove debris.

2. Checking Spoke Tension

  • Inspect spoke tension monthly, especially after hitting potholes or riding rough roads.
  • Uneven tension can cause instability and should be corrected with a spoke wrench.

3. Inspecting the Bearings

  • Every 3,000–5,000 miles, check the hub bearings for roughness.
  • If necessary, remove the axle, clean the bearings, and apply fresh grease.

4. Brake Surface and Rotor Care

  • For rim brakes, lightly sand the braking surface if braking performance decreases.
  • For disc brakes, clean rotors with isopropyl alcohol and ensure pads are not contaminated.

Troubleshooting Common Zipp 808 Issues

1. Wheel Wobbling or Poor Stability

  • Cause: Loose spokes, unbalanced tires, or misaligned axle.
  • Fix: Check spoke tension, re-seat the tire, and ensure the thru-axle or quick-release is properly secured.

2. Squeaking or Noisy Braking

  • Cause: Contaminated brake pads or worn braking surface.
  • Fix: Clean brake pads and rims; replace pads if necessary.

3. Reduced Speed or Efficiency

  • Cause: Over-tightened bearings, incorrect tire pressure, or excessive drag.
  • Fix: Adjust bearing preload, optimize tire pressure, and check for brake rub.

Customizing the Zipp 808 for Better Performance

1. Tire Selection for Speed and Comfort

  • Racing: Use high-TPI tires with low rolling resistance.
  • Training: Opt for slightly heavier, puncture-resistant tires.

2. Optimizing Aerodynamics

  • Pair with deep-section aero frames for maximum efficiency.
  • Use latex inner tubes or tubeless setups to reduce rolling resistance.

3. Upgrading to Ceramic Bearings

  • Swapping stock bearings for ceramic upgrades reduces friction and improves longevity.

Comparison: Zipp 808 vs. Other Deep-Section Wheels

The Zipp 808 competes with models like the Enve SES 7.8 and Roval Rapide CLX. Key differences include:

  • Weight: Zipp 808 is slightly heavier but offers superior aerodynamics.
  • Stability: Enve SES models handle crosswinds better.
  • Price: Zipp 808 is a premium option but offers long-term value.

Conclusion

The Zipp 808 wheelset is a top-tier choice for cyclists seeking speed and efficiency. Proper installation, adjustment, and maintenance will keep them performing at their best. Regular inspections, correct tire pressure, and bearing care ensure longevity and reliability. Whether you’re racing or training, optimizing your Zipp 808 setup will enhance your overall cycling experience.
