  Replace cables and housings every 6–12 months depending on riding conditions. Use genuine CUBE or high-quality aftermarket components to ensure compatibility and smooth operation. Proper cable tension ensures precise derailleur shifts and consistent brake lever feel, reducing the risk of failure during critical moments.

  Pro Tip: When installing new cables, apply a small amount of light lubricant (e.g., Teflon-based) to the inner wire to reduce friction and extend lifespan.

• Tire Maintenance

  Proper tire care prevents flats, improves rolling efficiency, and enhances ride comfort. Check tire pressure before every ride using a reliable floor pump with a gauge. CUBE carbon road bikes typically come with clincher tires (tube-type or tubeless-ready), and the recommended pressure range is printed on the tire sidewall.

  General pressure guidelines:

  • 700x25c: 90–110 psi
  • 700x28c: 80–100 psi
  • Tubeless setups: 60–80 psi (check sealant levels monthly)

  Low pressure increases the risk of pinch flats ("snake bites") and rim damage, especially on rough roads. Over-inflation can lead to reduced traction and a harsh ride. Also inspect tires for cuts, embedded debris, or worn tread. Replace tires when the center tread shows visible wear indicators or cracking.

• Washing and Cleaning

  Regular cleaning keeps your CUBE bike looking great and protects the carbon frame and components. Use lukewarm water and a mild, biodegradable soap with a soft sponge or microfiber cloth. Focus on the drivetrain (chain, cassette, chainrings), frame, and wheels.

  Avoid:

  • High-pressure water sprayers—these can force water into bearings, bottom brackets, and headset, leading to corrosion
  • Harsh chemical cleaners or degreasers near carbon surfaces
  • Leaving the bike in direct sunlight to dry, which can degrade carbon finishes over time

  After washing, dry the bike thoroughly with a clean towel. Lubricate the chain with a quality wet or dry lube depending on conditions, and wipe off excess to prevent dirt buildup.

• Hub and Bottom Bracket Inspection

  Hubs and bottom brackets are sealed units but can accumulate water, dirt, and grit over time, especially in wet or off-road conditions. Perform a monthly check:

  • Spin the wheels and feel for roughness or play in the hubs
  • Check the bottom bracket by holding the cranks and rocking them side-to-side—any movement indicates bearing wear
  • Listen for grinding noises during pedaling

  If issues are detected, the components may need servicing or replacement. Use manufacturer-recommended grease and tools when servicing. Proper lubrication reduces friction, prevents premature wear, and extends the life of expensive drivetrain components.
