The most important maintenance task. A dirty, dry chain wears out drivetrain components 3–5x faster than a clean, lubed one. After every 3–5 rides in dry conditions (after every ride in wet conditions): wipe the chain with a rag, apply 3–4 drops of chain lube to each link, let it soak for 10 minutes, then wipe excess off. Use wet lube for wet conditions; dry wax lube for dry dusty conditions.
Check tire pressure before every ride — tires lose 5–10 PSI per week even without punctures. Road bike tires: 80–120 PSI. Mountain bike tires: 20–35 PSI. Commuter/hybrid: 40–70 PSI. Overinflated road tires are harsh and puncture-prone; underinflated MTB tires cause pinch flats and rim damage. Inspect the tire surface for glass or embedded debris after every ride and remove with a fingernail or pick.
Squeeze both brakes before every ride — pads should contact the rim or rotor with 1–2 inches of lever travel remaining. Worn rim brake pads have wear lines that should remain visible. Hydraulic disc brake pads need replacing when under 1mm of material remains. Cable stretch is the most common cause of soft brake feel — the barrel adjuster at the brake lever tightens cables without tools.
When your bike skips gears, hesitates to shift, or won't go to the smallest cog, the cable tension is off. Turn the barrel adjuster (the small cylinder where the cable enters the derailleur) counterclockwise a quarter turn to add cable tension. Repeat until shifts are crisp. If barrel adjusting doesn't fix it, bring the bike to a shop for a limit screw and cable check.
DIY: chain lube, tire pressure, flat repair, barrel adjuster tuning, brake pad replacement. Shop: headset creaks, bottom bracket replacement, wheel truing, hydraulic brake bleeding, full drivetrain replacement, frame damage assessment. A good local shop does a $50–80 tune-up that covers everything and catches problems you'd miss. Annual tune-ups make a noticeable difference.
Lube the chain every 3–5 rides. Check tire pressure weekly. Full DIY inspection monthly. Professional tune-up annually for recreational riders, every 6 months for daily commuters. Bikes ridden in wet or muddy conditions need more frequent chain cleaning and drivetrain inspection.
Hex key set (3, 4, 5, 6, 8mm), a chain lube, clean rags, tire levers, a patch kit, and a floor pump with a pressure gauge cover 90% of home maintenance tasks. A chain checker tool ($15) monitors chain wear and tells you when to replace before it destroys your cassette.
