    Fitted 2 in my usual manner to my cross bike with some road tyres on and the punctured instantly once inflated. Upon inspection they were both found to be split where the valve meets the tube. Avoid

    Flat feeling

    The very first tube I used burst after installation. Upon inspection a half inch split had to be patched. After putting everything back together, later in the day the tube split again. Tyre was inflated to 110psi. I hope this was just a dud tube (pushing my bike home from work was no fun though)

    Great value branded tubes

    I have been tempted in the past to save money by buying very cheap tubes that turned out to be heavy leaky and prone to puncturing when fitting. With the 5 tubes bundle that Tredz offered here I reckon I've got the best of both worlds excellent branded tubes at very affordable prices. And this size conveniently fits both my bikes one with 23 and the other with 28 tyres. What not to like this was my first order with Tredz and I was delighted to see that the service was excellent and rapid.

    Inner Tubes Guide

     

    How To Choose The Right Inner Tubes For You

    It's inevitable you'll get a puncture at some point. When you do you'll need a spare bike inner tube with you. Use our simple bicycle inner tube guide to discover the right type for your bike.


    Wheel size diameter on tyre sidewall for correct inner tube sizing

    What Size Inner Tube Do I Need?

    Before buying a new bicycle inner tube, you'll want to make sure it will fit your wheel rims. The easiest way to do this is by looking at the tyres on your bike. On the sidewall you'll see a combination of digits such as:

    700x28c (road wheel) or 27.5x2.2 (mountain bike wheel)

    The first figure is the diameter of your wheel, the latter is the width of your tyre.

    Inner tubes will fit just one wheel size, so you'll need to match your new tube to your wheel diameter. However, inner tubes will cover a range of tyre widths.

    On a product page you'll find inner tubes are labelled with a series of digits:

    • 700 x 23-28c (for road bike tubes)
    • 29 x 1.75-2.4" (for mountain bike tubes)

    The first figure is your wheel diameter while the second two figures are the tyre widths the inner tube can be used with. As long as you match your wheel diameter, and your tyre width falls within the range stated, the tube will fit.



    ETRTO bike tyre sizing can be found on tyre sidewall

    ETRTO Sizing

    When looking at the side wall of your tyre you may see a combination of digits such as 54-559 or 23-622.

    This is ETRTO sizing but we recommend you use the Imperial/Metric sizing above as most cycle inner tubes we stock use this standard.

    Here is a comparrison chart for traditional and ETRTO sizing to help you choose the correct tyre size.

    Schrader & Presta Valve Compatibility

    The easiest way to determine if you need a Presta or Schrader inner tube valve is to again look at your current bike inner tube.

    Schrader Valve

    Schrader Valve

    Easily identified by the 'car type' stubby profile. These valves are often found on entry-level bikes which run on lower tyre pressures such as mountain bikes.

    Presta Valve

    Presta Valve

    Have a long and narrow profile. They have a central core you unscrew before inflating the tube.

    Presta valves are often used on road bikes which run at higher tyre pressures. These valves come in a range of lengths. Longer valves are designed for use with deep section aero rims.

    The Benefits Of Self-Sealing Inner Tubes

    Punctures are inevitable. Instead of having to lug around spare inner tubes with you, you can opt for a self-sealing inner tube. These bike inner tubes are delivered with tube sealant already inside. When you get a puncture the sealant will plug the gap so you can keep riding.
