GI (gastrointestinal) problems are common for marathon runners, long distance cyclists and triathletes; but there are ways to reduce GI, or elimitate it, with the correct nutrition approach. Latex tubes have also been proven in multiple tests to have lower rolling resistance, making them faster. Good" hubs and rims, not quality brand though but I've been told they're good and that's what almost everyone in this country uses.

Changing a punctured inner tube - or at least, removing and replacing it during a quick repair - is an inevitability, so it's a good idea to be capable of doing it quickly and with ease. For this purpose, we use your name and address, IP address, e-mail address, telephone number and billing address.Latex inner tubes are an alternative to the standard butyl rubber inner tubes that are commonplace in the market. The tube needs to fit your tyre to avoid overstretching or pinching, both of which are likely to cause punctures and the tube material needs to be appropriate for your style of riding.

Fading of colours on materials under the influence of sunlight is a natural process and is not covered by the product warranty.

If you have any questions or want to know what personal data we have of you, you can always contact us. Assuming you haven't changed the specification from when you originally bought the bike, then look for the tyre size in the product description, such as "Tyres: Continental UltraSport 700x25c". Now you know your tyre size and valve type, you can consider the extensive Inner Tube range at Wiggle. To confuse matters further all tyres use the European Tyre and Rim Technical Organisation (ETRTO) system, so for a road, it would display 622 x nn with the nn value indicating the tyre width which is the same as 700 x nn.

You must make sure you replace your inner tubes with a tube that is the right size according to the diameter and width for your tyre. The disadvantage of latex tubes is that they are a little trickier to fit, with a tendency to get caught between the tyre bead and the rim. To inflate or deflate a Presta Valve, the top section must be unscrewed, allowing the core of the valve to be free to move. Mountain bike riders will also often under inflate their tyres, sometimes quite significantly, to maximise grip, cornering, and shock absorbance.

As the rim drilling is the same for both Woods and Schrader, it is easy to replace the older tubes with the more modern variety. Again - as long as the tube isn't so stretched that it's prone to failure, or doesn't have enough room to expand smoothly and creates kinks/folds, the tube doesn't matter. Changing an inner tube, as anyone who has been caught out by the side of the road will know, is a necessary evil. We would like to know: brand / model / type, year of manufacture, coach work, fuel, automatic transmission or manual, number of doors, VIN.
