Mountain Bike Maintenance Tips: Keep Your MTB Running Smoothly

Mountain bikes take more punishment than any other type of bicycle. Mud, water, rocks, and impacts all accelerate wear. Here's how to keep your MTB in top condition and avoid expensive repairs.

After every ride

• Hose off mud — don't let it dry on. Use low pressure, never a jet wash
• Wipe the stanchions — fork and shock stanchions should be clean and free of grit
• Wipe the chain — a quick wipe removes the worst of the grit
• Check for damage — look for dents, cracks, or bent components after rough rides

Weekly maintenance

Drivetrain

• Clean and degrease the chain, cassette, and chainring
• Apply wet lube (MTBs are almost always in wet/muddy conditions)
• Check chain wear — MTB chains wear faster than road chains
• Check derailleur hanger alignment — impacts can bend it without you noticing

Brakes

• Check pad thickness — MTB pads wear fast in gritty conditions
• Clean rotors with isopropyl alcohol
• Check lever feel — spongy levers mean air in the system
• Listen for rubbing — realign calipers if needed

Tyres

• Check for cuts, tears, and embedded thorns
• Top up tubeless sealant every 2–3 months (it dries out)
• Check tyre pressure before every ride — MTB pressures are low and drop quickly
• Rotate tyres if the front is wearing faster than the rear (or vice versa)

Monthly maintenance

Suspension

Your fork and shock are precision instruments with seals, oil, and air chambers. They need regular attention:

• Wipe stanchions with a clean cloth after every ride
• Check air pressure monthly with a shock pump
• Lower leg service every 50 hours of riding (or every 3–6 months)
• Full service annually — damper oil change, seal replacement

Bearings

• Check headset for play — grab the fork and rock the bike
• Check bottom bracket — spin the cranks and feel for grinding
• Check pivot bearings (full suspension) — feel for play at each pivot point
• Check wheel hub bearings — spin the wheel and listen for roughness

Seasonal deep service

Every 6 months (or more often if you ride hard), book a full service:

• Full drivetrain strip, clean, and assessment
• Brake bleed (both brakes)
• Bearing check and repack
• Wheel true and spoke tension
• Bolt torque check throughout
• Suspension service (lower legs at minimum)

Common MTB problems to watch for

• Chain suck: chain gets stuck between chainring and frame — usually a worn chainring
• Ghost shifting: gears shift on their own over bumps — bent hanger or cable tension
• Suspension bottoming out: not enough air pressure or too much sag
• Tubeless burping: tyre unseats momentarily in hard corners — check sealant and pressure
• Creaking suspension: dry pivot bearings or loose bolts
