That’s why with our 2 year warranty (starting from the date of purchase) we will replace any defective item that does not live up to our standards of quality and unbeatable value. Mountain bike riders will also often under inflate their tyres, sometimes quite significantly, to maximise grip, cornering, and shock absorbance. They look like a cross between the two valves, with a wider lower section, like the Schrader, then a collar and a narrow top section, like the Presta. 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.

When the Dresco tires are inflated to the correct pressure, the rolling resistance is lower and they offer excellent driving comfort. 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. Schrader valves have a core that is sprung loaded, and the central pin can be depressed with a narrow object to release air from the tube. I recycled my dad's road bike (about 20 years left in storage) so I bought a complete set of new wheels. These pieces of information are used to create a user profile and deliver personalized ads that align more closely with their interests.Now you know your tyre size and valve type, you can consider the extensive Inner Tube range at Wiggle. We save this information so that you do not have to fill it in again each time and so that we can contact you in connection with the performance of the contract.

Schrader valves, pictured right in the image below, are shorter and fatter (found on car and wheelbarrow tubes).Please also note that although this listing is for a specific size, all tubes fit a range of tyre widths and this will be evident from the packaging or sizing shown on the tube itself. While trying to figure out what pressure I should use I came to realize that the tires are 28" x 1" 1/8 (700x28) and the inner tube is 700 x 18-23 which to me seems quite a lot.
