A practical, at-home bike service guide from working mechanics. Learn the essential tools, a methodical workflow, and the safety checks that keep your bike running smoothly.
Who this guide is for
This guide covers a thorough home bicycle service suitable for most hybrid, road, gravel and mountain bikes. It’s ideal if you want a full safety check, smoother shifting and braking, and a reliable bike for everyday rides, charity events, or a supported bike ride.
Note: We always recommend a professional mechanic for advanced jobs or if you’re unsure. If you need a bike ready for an event, hire a bike can be more
Tools
- Allen key set (hex keys)
- Screwdrivers (Phillips & flat)
- Chain lube
- Light penetrating spray (e.g., TF2)
- Floor pump with gauge
- Bike stand (optional but helpful)
- Torx set (T25 commonly used on disc rotors)
- Pedal spanner or 6/8 mm hex (for pedal axles)
- Clean rags and mild bike cleaner
- Torque wrench (recommended)
The key points
- Be methodical: Work front-to-back or top-to-bottom so nothing gets missed.
- Slow is smooth: Adjust one thing at a time. Test. Then move on.
- Use correct torque: Over-tightening can damage parts; under-tightening can be unsafe.
Step 1 — Tyres & Wheels
- Inflate tyres to the PSI on the sidewall. Check for cuts, embedded flints, and worn tread.
- Ensure wheels are seated correctly in the dropouts. Tighten quick-releases/axle bolts to spec.
- Spin each wheel—look for side-to-side wobble. Minor rub can often be fixed with pad centring; significant wobbles require truing.
Step 2 — Brakes
Squeeze both brakes firmly and check for rubbing, spongy feel, or weak bite.
- Cable rim brakes (V-brake/caliper): Ensure pads hit the braking surface squarely; centre the brake arms; set lever travel.
- Mechanical disc: Centre the caliper, set pad clearance using inboard/outboard adjusters if present, then set cable tension.
- Hydraulic disc: Check rotor straightness and caliper alignment. If the lever feels spongy or pulls to the bar, it likely needs a bleed (a shop job for most riders).

Step 3 — Gears & Drivetrain
- Clean chainrings, cassette and jockey wheels; wipe the chain and re-lube sparingly.
- Shift one gear at a time while pedalling steadily. The chain should climb and drop crisply without skipping.
- Fine-tune cable tension using the barrel adjuster. Check front shifting (if fitted) across the full range.
- For Di2/electronic groupsets, use micro-adjust as needed; update firmware periodically.

Step 4 — Headset & Steering
- With the front brake on, rock the bike. Any play at the headset indicates loose preload or worn bearings.
- Turn bars lock-to-lock—binding or grittiness usually means the bearings need service or replacement.

Step 5 — Bottom Bracket & Cranks
- Hold a crank arm and try to move it side-to-side (not fore-aft). Any movement suggests bearing wear or loose hardware.
- Check chainring bolts and crank-fixing bolts to manufacturer torque specs.
Step 6 — Controls & Contact Points
- Ensure brake levers and shifters are securely clamped and aligned.
- Check saddle angle and height; tighten saddle rail clamp evenly.
- Confirm seatpost is greased (alloy/steel) or carbon-pasted (carbon) and clamped to spec.
- Check pedals are tight and spin freely.

Bolt Tightening Checklist
Always use manufacturer torque values. If you need general guidance, Park Tool maintains an excellent reference — check here.
- Wheels: Thru-axles/QRs tightened and closed correctly
- Brake rotors (T25) and caliper mount bolts
- Front & rear derailleurs: main mount bolt + cable pinch bolt (if applicable)
- Handlebar controls: brake lever and shifter clamps
- Stem faceplate and steerer clamp + top cap preload (follow correct sequence) – https://youtu.be/F_yCCCA3DEg
- Cranks and chainring bolts
- Pedals
- Seatpost clamp + saddle rail clamp
When to see a professional mechanic
Book your local shop if you find: persistent brake rub after alignment, spongy hydraulic levers, severe wheel wobble, cracked components, seized parts, or bottom bracket/headset play that returns after tightening.
Getting ready for a big ride? Sometimes hiring a bike that perfectly fits the event saves time and money—especially for supported charity rides or multi-day challenges.
FAQs
How often should I service my bike?
For regular riders, every 6–12 months or every 1,000–2,000 miles is a good rule of thumb. Wet/muddy riding shortens intervals.
What’s the best lube for UK conditions?
Use a quality wet lube for year-round commuting and winter, and a dry lube for dry summer conditions. Wipe excess to avoid grit build-up.
Do I need a torque wrench?
Highly recommended—especially for carbon components and stems/seatposts. Correct torque prevents damage and keeps you safe.
Can I bleed hydraulic disc brakes at home?
Yes with the right kit and procedure, but if the lever still feels spongy or you’re unsure, book a professional bleed.
Is it cheaper to repair or to hire for an event?
It depends on parts and labour. For one-off events, bike hire can be more economical and ensures event-ready spec.
