5 Bike Repairs You Can Do Without a Shop Visit

These are the fixes I actually perform on the roadside or in my garage. They’re simple, repeatable, and don’t require a full workbench. Learn them once and you’ll ride calmer, farther, and cheaper.

1) Fix a Flat Tire (Tube or Tubeless)

• Carry the basics: two tire levers, a spare tube, a patch kit, and either a mini pump or CO₂ inflator.
• Tube setup: pop off one bead with levers, remove tube, check the tire for thorns/wire, install new tube with a little air, re-seat bead, inflate.
• Tubeless: spin the sealant to the puncture; if it won’t seal, insert a bacon strip/plug, reinflate, and roll the tire to distribute sealant.
• Pro tip: always inspect the inside of the tire with your fingers—carefully—to avoid re-flats from hidden debris.

2) Rescue a Dropped or Skipping Chain

• Dropped chain: shift the front to the smallest ring and rear to mid-cassette, lift the chain back onto the ring, pedal gently.
• Skipping under load often means a stretched chain or worn cassette. Check with a chain checker and replace before it trashes the cogs.
• Carry a spare quick link for your speed (10/11/12-speed) and learn the 60-second trail fix.

3) Quiet Squeaky Brakes (Disc or Rim)

• Disc: loosen the two caliper bolts, squeeze the brake lever to center the caliper, hold lever while you re-tighten bolts. Wipe rotors with alcohol.
• Glazed or contaminated pads? Lightly scuff on clean sandpaper; replace if soaked with oil. Keep lube far from rotors.
• Rim: align pads so they hit the braking surface squarely; toe-in slightly to reduce squeal.

4) Smooth Out Bad Shifting (Barrel Adjuster Magic)

• If it hesitates going to a larger cog (easier gear), add cable tension: turn the barrel adjuster counter-clockwise 1/4 turn at a time.
• If it hesitates going to a smaller cog (harder gear), reduce tension: turn the barrel adjuster clockwise.
• If adjustment won’t save it, replace the cable/housing and reset limit screws.

5) Stop Random Creaks and Rattles

• Systematically check: seatpost clamp, saddle rails, stem faceplate, pedal threads, crank bolts, bottle cages. Tighten to spec.
• Remove/clean/re-grease metal-on-metal interfaces (seatpost in alloy frame, pedal threads). Carbon assemblies may need paste—follow manufacturer guidance.
• A torque wrench prevents over-tightening—especially important with carbon bits.

My Compact DIY Toolkit (What Lives in My Saddle Bag)

• Multi-Tool, Tire Levers, Tube, Patch Kit
• Mini Pump or CO₂ Inflator + cartridges

• Travel-size Chain Lube & wipes

I keep the torque wrench at home; everything else fits in a compact bag.

FAQ

What’s the minimum tool kit I need to carry?

Multi-tool, two tire levers, spare tube, patch kit, pump or CO₂, a quick link, and a few wipes. That solves 90% of roadside issues.

Are CO₂ inflators better than a mini pump?

They’re faster and smaller, but single-use. I carry both: CO₂ for speed, mini pump as a backup so I’m never stranded.

When should I skip DIY and go to a shop?

Hydraulic bleeding, wheel truing beyond a minor wobble, bottom bracket play, or persistent shifting problems after new cables—let a pro handle those.
