Caring for Your Montu Carbon Bike

Carbon framesets reward a little attention. Here's how to keep your Kopis, Osiris, or Nui V2 riding — and looking — its best for years.

1Cleaning & General Care

Carbon fibre is strong and durable, but its finish and bonded components deserve gentle, regular care. A clean bike is also an easy bike to inspect — dirt hides the chips and cracks you want to catch early.

Do

  • Wash with lukewarm water, mild dish soap, and a soft sponge or brush.
  • Rinse gently — a light hose flow or bucket is plenty.
  • Dry with a soft microfibre cloth after every wet wash.
  • Use a dedicated bike wash or carbon-safe cleaner for stubborn grime.
  • Apply frame polish or protectant sparingly to the painted surfaces only.

Avoid

  • Pressure washers — they force water and grit into bearings and bonded joints.
  • Solvents, degreasers, or petroleum products on the frame finish.
  • Abrasive pads or scouring brushes that scratch clear-coat.
  • Spraying directly into the headset, bottom bracket, or hub seals.
  • Leaving the bike wet — trapped moisture invites corrosion at metal interfaces.

Keep degreaser on the drivetrain where it belongs (chain, cassette, derailleur pulleys) and off the frame. Wipe the chain down and re-lube after any wet or dusty ride.

2Torque & Fasteners

Correct fastener torque is critical on a carbon bike — both for your safety and for the longevity of the frame and components. Always use a calibrated torque wrench, and never exceed the value printed on a component. When in doubt, have a qualified bicycle mechanic torque your fasteners.

Important: The values below are maximum torque specs. Tighten gradually and in stages, alternating between bolts where a part uses more than one. Use carbon assembly (friction) paste on seatpost and bar/stem clamp interfaces — it lets you reach holding force at lower torque.
Component Kopis Osiris Nui V2 Notes
Seatpost wedge bolt 6–7 Nm 6–7 Nm 6–7 Nm Use carbon friction paste on the seatpost.
Stem clamp bolts 5 Nm 5 Nm 5 Nm Use low-strength thread-lock. Apply friction paste inside the stem clamp where it contacts the handlebar.
Expander compression bolt 5–6 Nm 5–6 Nm 5–6 Nm Use carbon paste on the inside of the steerer tube, between the tube wall and the expander plug.

Values are maximum torque specifications for Montu framesets. Always defer to the torque value printed on an individual component.

3Racks & Transport

How you carry your bike matters as much as how you ride it. The golden rule for carbon: never use a rack that clamps or presses against the frame tubes. Clamping force concentrated on a carbon tube can crack it, and the damage often isn't visible until it fails.

  • Best — wheel-clamp platform racks. These secure the bike by the wheels/tyres and never touch the frame. Example: Thule T2 Pro.
  • Also great — vertical / hanging racks that hold by the wheels. Example: Thule Revert.
  • Avoid — trunk and hitch racks with frame-clamp arms. If you must use one, fit a rigid frame protector or a dummy crossbar and never clamp directly on a carbon tube.
On the road: double-check wheel straps after the first few minutes of driving, and again at stops. Remove computers, lights, and bottles before transport.

Not sure which rack suits your vehicle and your bike? Get in touch — we'll connect you with trusted local dealers carrying the racks we recommend for carbon framesets.

4Storage & Humidity

Carbon doesn't rust, but the metal hardware, bearings, and cables on your bike do. Store smart and everything lasts longer.

  • Store indoors in a cool, dry space away from direct sunlight — prolonged UV exposure can dull clear-coat and degrade tyres.
  • Keep the bike clean and dry before storing for any length of time.
  • Avoid damp basements, sheds, or anywhere humidity sits high; moisture promotes corrosion at every metal interface.
  • For long-term storage, hang the bike or support it so the tyres aren't bearing full weight against a cold floor.
  • Never store near furnaces, heaters, or in a hot vehicle — extreme heat is not friendly to resins or tyres.

5Post-Ride & Wet-Ride Routine

A few minutes after a wet or dusty ride saves a lot of wear down the road.

  • Rinse off mud and road grime gently while it's still soft — dried grit is abrasive.
  • Dry the frame, then wipe down the chain and re-lube it.
  • Pay attention to areas where water collects: under the bottom bracket, around the seatpost collar, and at cable entries.
  • If you ride frequently in the wet, periodically remove the seatpost, dry the inside of the frame, and re-apply friction paste before reinserting.
  • Check tyre pressure and give the drivetrain a quick once-over before your next ride.
