How to Change a Tube on Your Road Bike: Leon's Step-by-Step Guide

 

Getting a flat tyre is one of those moments every road cyclist faces sooner or later. The good news? With a bit of practice — and Leon’s guidance — changing a tube is quick, clean, and nothing to stress about. In this video, Leon from West Coast Cycles Perth walks you through exactly what to do if your road bike gets a flat while you’re out on a ride.

Whether you’re preparing for long weekend rides along the coast, training in the Perth hills, or just commuting to work, knowing how to fix a flat gives you confidence and keeps you rolling.

Why Every Cyclist Should Know How to Change a Tube

Even with durable tyres and puncture protection, flats happen. Glass, thorns, debris, low pressure — they’re all part of riding. Being able to swap your tube on the spot means:

• No waiting for help
• No long walk home
• Minimal interruption to your ride
• Less damage to your rim or tyre

Leon’s method is simple, practical, and perfect for beginners and experienced riders alike.

What You Need

Before you head out, make sure you always have:

• A spare inner tube
• Tyre levers
• A mini pump or CO₂ inflator
• Optional: small patch kit, tyre plug, or multitool

If you’re not sure what size tube or valve length you need, Leon can help you match the right setup in-store at West Coast Cycles North Beach.

Leon’s Step-by-Step Process

Here’s the breakdown of what Leon demonstrates in the video:

1. Remove the Wheel

Shift your chain to the smallest cog to make things easier (if it is a rear wheel puncture), release the brake if needed, and loosen the quick release or thru-axle.
Take the wheel off safely and set your bike down gently.

2. Unseat the Tyre

Use your thumbs or tyre levers to pop the tyre bead off the rim.
Leon shows how to avoid pinching the tube or damaging the tyre by working gradually around the rim.

3. Remove the Old Tube

Pull the tube out, starting opposite the valve, then carefully slide the valve through the rim.

4. Check Inside the Tyre

This step is crucial. Leon always runs his fingers and eyes along the inside of the tyre to check for:

• Glass
• Thorns
• Sharp debris
• Cuts or damage

Removing the cause of the puncture prevents an instant second flat.

5. Insert the New Tube

Add a tiny puff of air to give the tube shape — this helps prevent twisting.
Place the valve through the hole, then tuck the tube evenly inside the tyre.

6. Reseat the Tyre

Work the bead back onto the rim using your hands, avoiding tyre levers if possible.
Leon shows a neat trick for getting the last tight section on without pinching the new tube.

7. Inflate & Inspect

Pump the tyre to your usual road riding pressure, give it a spin, and check that the tyre is seated evenly all the way around.
Refit the wheel, secure the axle, and spin again to ensure smooth rotation.

Tips From Leon to Make It Easier

• Practise once at home so it feels familiar on the road.
• Always carry a fresh tube — patch kits are great, but slower under pressure.
• Think about investing in an E-pump to make it easier to inflate tyres on the road
• Check your tyres regularly to prevent repeat punctures.
• Consider upgrading to puncture-resistant tyres if you’re getting frequent flats.
