How To Tune Up a Bike

ERIC KIM MODE: ENGAGED — let’s rocket-launch your bike into god-tier performance.

A bike tune-up isn’t maintenance… it’s a spiritual cleansing. It’s you declaring to the universe: I ride with precision, power, and zero drag. Let’s turn your humble machine into a frictionless freedom rocket.

1. CLEAN THE BIKE — PURIFY THE MACHINE

Before anything else: remove all grime, dust, past sins.

A dirty bike is a slow bike. A clean bike is a fast philosophy.

  • Hose lightly or wipe by hand
  • Bike-specific soap or simple dish soap
  • Degrease chain, cassette, chainrings
  • Wipe perfectly dry

Your bike should glisten like a katana.

2. LUBRICATE THE CHAIN — THE SECRET SAUCE OF SPEED

Your chain is your power-transmission. Treat it like a Formula 1 drivetrain.

  • Use a good chain lube (dry lube for dry environments, wet lube for wet conditions)
  • Drop a tiny bead on each link
  • Spin cranks
  • Wipe off excess (most people OVER-lube)

A well-lubed chain feels like butter on ice.

3. ADJUST THE BRAKES — STOP LIKE A JAGUAR

You want power braking, not sponge braking.

  • Check pads for wear
  • Align pads with rim or rotor
  • Tighten cables
  • Make sure levers engage smoothly

When tuned right, braking should feel telepathic.

4. TUNE THE GEARS — SHIFT LIKE A LASER

A well-tuned drivetrain is pure joy.

  • Put the bike on a stand (or flip it upside down)
  • Use barrel adjuster to fix slow or skipping shifts
  • Limit screws (H & L) prevent chain from over-shifting
  • Check cable tension

When perfected, gears click with sniper precision.

5. TRUE THE WHEELS — ZERO WOBBLE

Even a slight wobble steals power from your pedal stroke.

  • Spin wheels
  • Check for side-to-side wobble
  • Adjust spoke tension using a spoke wrench
  • Or take to a shop if you want perfection

Straight wheels = maximum velocity.

6. INFLATE TIRES — THE FREE SPEED BOOST

Most people ride with slightly underinflated tires.

You? No. You ride with optimal PSI like a champion.

  • Road bikes: ~80–110 PSI (depending on weight + comfort)
  • Gravel/hybrid: 40–60 PSI
  • MTB: 20–35 PSI

Higher PSI = less rolling resistance = faster ERIC KIM.

7. CHECK BEARINGS — SMOOTHNESS IS GOD

Bottom bracket, hubs, headset.

If anything feels gritty, rough, or loose:

  • Re-tighten
  • Re-grease
  • Replace if needed

A bike with perfect bearings feels alive.

8. BOLT CHECK — TIGHTEN EVERYTHING

Not over-tight—just snug and safe.

  • Stem
  • Bars
  • Seatpost
  • Cranks
  • Pedals

This is your exoskeleton. Secure it.

9. TEST RIDE — FEEL THE POWER

Shift through all gears

Brake hard

Sprint

Stand and climb

A tuned bike should feel like it wants to leap forward with every pedal stroke.

10. FINAL TOUCH — ERIC KIM STYLE

  • Remove unnecessary accessories → minimalist = faster
  • Clean lines, clean frame, no baggage
  • Bike as sculpture
  • Bike as freedom

Your bike is not just transportation — it is the expression of your will to move through the world with power.

If you want, I can tailor a tune-up checklist specifically for your bike type (road, gravel, mountain, fixed, folding, etc).
