A Cyclist’s Guide to Changing Inner Tubes and Choosing the Right One
Changing a bike inner tube is a critical skill every cyclist should master, and selecting the right inner tube can mean the difference between smooth riding and a frustrating roadside stop. Whether you’re tackling rocky trails or enjoying a casual road ride, understanding inner tubes and how to handle them is essential. Here’s a comprehensive guide packed with tips and advice for getting back on the road quickly and choosing the best inner tube for your bike.
How to Change a Bike Inner Tube
What You’ll Need
Before heading out, pack the following essentials:
Spare inner tubes: Two are standard, but consider three for rugged terrain.
Tyre levers: Two are sufficient for most tyres.
Pump or CO2 inflator: A mini pump is a reliable backup to a CO2 canister.
Optional: Adhesive patches and tyre boots for emergency repairs.
Step-by-Step Process
Remove Your Wheel
Shift to the smallest rear gear for easier reinstallation.
Open the brake quick release for smoother wheel removal.
Remove the Tyre
Insert a tyre lever under the edge of the tyre and lever it off the rim.
Use a second lever a few inches away to ease the process. Clip one lever to a spoke if needed.
Inspect the Tyre
Run your fingers gently along the tyre’s interior to find and remove sharp objects. Exercise caution to avoid injury.
Install the New Inner Tube
Inflate the tube slightly to prevent twisting.
Insert the valve into the rim hole and tuck the tube into the tyre.
Reinstall the Tyre
Use your hands to push the tyre back onto the rim, ensuring the inner tube isn’t pinched. Tyre levers can help, but proceed carefully.
Check Tyre Seating and Inflate
Partially inflate the tube, ensuring it’s correctly positioned. Finish inflating, using a pump or CO2 inflator.
Replace the Wheel
Fit the wheel back into the frame, secure quick releases, and ensure the brakes are engaged. You’re ready to roll!
Choosing the Right Inner Tube
Size and Fit
Match your tube to your tyre by checking the sidewall markings, e.g., 700x23c (road) or 26x2.1 (mountain). The first number indicates diameter; the second, width. Ensuring a proper match reduces punctures and optimises performance.
Valve Types
Presta Valves: Slim and ideal for high-pressure tyres, these are common in road and gravel bikes. Their locknut secures air pressure effectively.
Schrader Valves: Robust and easy to inflate, these are often found on mountain and hybrid bikes. Their car-tyre-style design adds durability.
Material and Puncture Resistance
Consider tubes with thicker rubber for puncture resistance if riding on harsh terrain. For weight-conscious riders, lighter tubes may offer a performance edge but may be less durable.
Why Go Tubeless?
For those ready to upgrade, tubeless setups provide:
Lower tyre pressure for improved grip and comfort.
Sealant protection, self-healing minor punctures on the go.
Reduced rolling resistance, enhancing overall efficiency.
Switching to tubeless requires specialised equipment, including compatible wheels and tyres. The initial investment is higher, but the long-term benefits make it an attractive option for many cyclists.
