Buyer's guide to inner tubes — how to save weight, ride faster or prevent flats with new tubes

How the simple rubber ring isn’t so simple You probably don’t think very much about inner tubes, but the components that hold the air that in turns holds your bike off the ground have a subtle but significant on the way your bike rides and performs.

Inner tubes affect the rolling resistance of your tyres, how easily you can end up sidelined with a puncture and the rotating weight of your wheels. If you care about performance — whether you mean by that speed or robustness and reliability — it’s worth thinking about the inner tubes you use beyond just where you can get 10 for £20. Rolling resistance

The rolling resistance of tyres comes from the force needed to bend the tyre where it contacts the road. But the inner tube has to bend too, so if it’s thick, then the rolling resistance of the whole combination goes up too.

The flexibility of the inner tube material makes a difference too. Inner tubes are made from either synthetic butyl rubber or natural latex rubber. Latex is more flexible and thinner too, so if you want to reduce rolling resistance then latex is the way to go. According to Jarno Bierman […]
