Checklist Items (24)
Pre-ride Inspection
Perform a quick overall check before each ride to catch obvious issues.
Inspect tires for damage
Look for cuts, punctures, embedded debris, or sidewall cracks; replace if damage is deep.
Test brake lever feel
Squeeze each brake lever; it should feel firm and engage the wheel before the lever hits the handlebar.
Drivetrain Maintenance
Keep the chain, cassette, and chainrings clean and properly lubricated for smooth shifting.
Check chain wear
Use a chain checker tool; replace if elongation exceeds 0.5% (1/16 inch over 12 inches).
Inspect cassette and chainring teeth
Look for hooked or worn teeth; replace cassette or chainrings if shaping is uneven.
Lubricate chain and wipe excess
Apply a drop of lube to each roller, let penetrate, then wipe off excess with a rag.
Brakes
Ensure brakes provide reliable stopping power and are free of contamination.
Inspect brake pad wear
For rim brakes, ensure pad grooves are visible; for disc brakes, check pad thickness >1mm.
Check brake cable tension or hydraulic fluid
For cable brakes, adjust barrel adjuster for slight lever play; for hydraulics, check fluid level and top off if needed.
Test brake lever reach and feel
Lever should engage smoothly; adjust reach screw if fingers cannot comfortably grasp lever.
Verify rotor/truing or rim braking surface
Look for warped rotors (side-to-side wobble) or glazed rim surfaces; clean with isopropyl alcohol if needed.
Wheels & Tires
Check hubs, spokes, and tire seating for safety and performance.
Remove wheel (quick-release/thru-axle)
Open quick-release lever or unscrew thru-axle, then lift wheel out of dropouts.
Inspect hub bearings for play
Hold wheel and try to wiggle side-to-side; any play indicates need for bearing adjustment or replacement.
Check spoke tension
Squeeze pairs of spokes; they should feel firm and similar; loose spokes need tightening.
Install wheel and secure axle
Seat wheel fully in dropouts, close quick-release lever firmly or torque thru-axle to manufacturer spec.
Frame & Cockpit
Inspect frame integrity and ensure controls are tight and comfortable.
Inspect frame for cracks or damage
Look at welds, joints, and tube surfaces for any cracks, dents, or paint lifting.
Check headset for play
Apply front brake and rock bike forward/backward; any knocking indicates headset looseness.
Tighten stem and handlebar bolts
Use a torque wrench to tighten stem bolts to spec (usually 5-7 Nm) and handlebar clamp bolts.
Verify saddle height, tilt, and pedal condition
Ensure saddle is at proper height, level, and securely clamped; check pedals for smooth rotation.
Final Check & Lubrication
Apply finishing lubricants, perform a test ride, and record the service.
Lubricate derailleur pivots and brake pivots
Apply a light oil to pivot points; move parts to work in lubricant, then wipe excess.
Lubricate cable housings (if applicable)
Add a few drops of light oil into cable ends or use a cable lubricator for smoother actuation.
Take short test ride, listen for noises
Ride a few minutes, shift through gears, brake firmly; listen for creaks, clicks, or rubbing.
Record maintenance date and observations
Write down date, mileage, and any parts replaced or issues noted for future reference.
