Product Information

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. Inner tubes are normally made of butyl rubber or Latex, they sit inside your tyre and are inflated with a pump, they sometimes puncture but are easily replaced.

I recycled my dad's road bike (about 20 years left in storage) so I bought a complete set of new wheels. 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.

This gives you a qualitatively reliable inner tube that keeps the tyre at the required pressure for longer.

On bikes, Schrader valves tend to be used on lower pressure tyres, such as kids's bikes and mountain bikes. Now you know your tyre size and valve type, you can consider the extensive Inner Tube range at Wiggle. The Dunlop valve, also known as a Woods is a variation of pneumatic valve that is rarely used on modern bikes.Presta inner tubes are available in different valve lengths to be appropriate for use in deep section rim profiles. I don't care much about pressure since I do not intend to compete, just commuting and eventual light-training in the city. This gives you a qualitatively reliable inner tube that keeps the tire at the desired pressure for longer.
