Bike tune-up spring

Why: Having everything at hand prevents interruptions and ensures you use the correct tools for delicate components.

How:

• Collect a set of metric hex keys (2mm-8mm), a Phillips screwdriver, and a torque wrench.
• Prepare cleaning supplies: a bucket of warm water, biodegradable bike cleaner, a soft brush, and a microfiber cloth.
• Get a floor pump with a pressure gauge and specific chain lubricant.

Done when: All tools and cleaning agents are laid out next to the bicycle.

Why: Dirt and salt from winter storage can hide cracks in the frame and accelerate wear on moving parts.

How:

• Spray the frame with cleaner and let it sit for 2-3 minutes (avoid direct high pressure on bearings).
• Use a soft brush for the frame and a stiffer brush for the cassette and chainrings.
• Rinse with a gentle stream of water and dry thoroughly with a cloth to prevent rust.

Done when: The bike is free of visible dirt, grease buildup, and road salt.

Why: A worn chain will quickly destroy expensive cassettes and chainrings if not replaced in time.

How:

• Use a chain checker tool; if the 0.75% side drops in, the chain needs replacement.
• If you don't have a tool, measure 12 complete links: they should be exactly 12 inches (30.48 cm). If it's over 12 1/16 inches, replace it.
• Check for stiff links by back-pedaling slowly.

Done when: You know exactly if your chain is safe to ride or needs replacement.

Why: Proper lubrication reduces friction, prevents rust, and ensures crisp shifting.

How:

• Apply one drop of lubricant to each individual roller while back-pedaling.
• Let it soak in for 5 minutes, then use a clean rag to wipe off ALL excess oil from the outside.
• Use 'Dry Lube' for dusty conditions or 'Wet Lube' if you expect spring rain.

Done when: The chain is lubricated internally but feels dry to the touch on the outside.

Why: Worn pads significantly increase stopping distance and can damage rims or rotors.

How:

• Rim brakes: Ensure grooves are still visible; if the pad is smooth, replace it.
• Disc brakes: Remove pads and check thickness; if the friction material is less than 1.5mm, replace them.
• Sand the pads slightly with fine-grit sandpaper if they appear 'glazed' or shiny.

Done when: Brake pads are confirmed to have sufficient thickness and a clean surface.

Why: Cables stretch over time, leading to a 'mushy' feel and poor braking performance.

How:

• Turn the barrel adjuster at the lever or caliper to take up slack.
• Ensure pads hit the rim/rotor squarely and simultaneously.
• If the lever pulls all the way to the handlebar, loosen the anchor bolt, pull the cable tighter, and re-tighten.

Done when: Brakes engage fully when the lever is pulled about 1/3 of the way to the grip.

Why: Tires lose air over winter (permeation) and rubber can develop dry-rot cracks.

How:

• Inspect sidewalls for cracks and the tread for embedded glass or sharp debris.
• Inflate to the recommended PSI range printed on the tire sidewall (usually lower for comfort/grip, higher for speed).
• Spin the wheels to check for 'trueness' (wobbling); if they wobble more than 2mm, they need professional truing.

Done when: Tires are at the correct pressure and show no signs of structural failure.

Why: Vibrations can loosen bolts, which is a major safety hazard, especially for handlebars and pedals.

How:

• Check the stem bolts (usually 4-6 Nm), seatpost clamp, and crank bolts.
• Ensure pedals are tight (remember: left pedal is reverse-threaded).
• Tighten any loose accessories like mudguards, racks, or bottle cages.

Done when: All critical bolts are tightened to the manufacturer's torque specifications.

Why: A controlled test ride identifies issues like gear skipping or strange noises before you go on a long trip.

How:

• Ride in a safe, flat area away from traffic.
• Shift through all gears to ensure smooth transitions.
• Perform several controlled stops to bed in the brakes.
• Listen for clicks, squeaks, or rattles that might indicate loose parts.

Done when: The bike shifts, brakes, and handles perfectly during a 5-minute ride.
