Seamless Latex Innertube

Save up to 3 watts per wheel


Latex inner tubes are far more supple than normal butyl tubes. They adapt quickly to the tire changing shape while cornering and rolling. The unique Challenge seamless latex inner tube saves more than 3 watts per wheel over a butyl inner tube according to German, Finnish, Belgian, Dutch, UK and American testing.

Lighter, softer, more supple (#)

The lighter, softer, more supple tube reduces rolling resistance and improves comfort, traction and cornering. This is because latex extends and expands 7 to 8 times its original size, whereas butyl only about 1.5 times, which means latex is much, much more flexible, guaranteeing more speed, improving rolling resistance and comfort than a standard butyl tube.

Latex inner tubes also weigh less than standard butyl tubes so can help save weight.

They also increase puncture protection; the latex stretches and deforms around the body which is trying to penetrate the tube instead of, like the stiffer butyl, trying to resist the body and shortly after, being punctured through with a big blow.

The highly elastic latex material is extremely more difficult to puncture and in the unlikely case that it is, the air will anyhow come out very slowly, because the elastic latex, punctured at that point, will move slightly and still stick and conform to the object so not leaving a big tear and gaping hole. The slight leaking of air in that point means that if you are riding and have no spare, you may still be able to ride most of the way back while it very, very slowly looses air, but you won’t be stranded somewhere out there with a sudden flat!

Key advantages of latex inner tubes (#)

  • The only Seamless ‘one-piece’ latex inner tube on the market
  • Seamless & smooth, no bumps at the valve,
  • No “out of round, unbalanced” wheel
  • Improves rolling resistance and comfort
  • Strong and extremely elastic, thus very reliable
  • Improves resistance to punctures
  • Is lighter weight than standard butyl and some superlight butyl tubes
  • Has a two-piece removable valve core for valve extender use
  • Two sizes: for Road/wider Road 19-28mm and for wider Road/Adventure 29-38mm
  • By far the cheapest way of improving the performance and overall feel of your bike!

Warnings and suggestions for optimal use (#)

Latex is more porous and gas permeable meaning that a tire with a latex tube should be checked before every ride, to make sure that it has retained your desired pressure.

Installation of a latex tube is also not so easy and can be tricky for the inexperienced hand. It can be more prone to pinch flats if not installed properly. The suppleness of latex means it can find its way into the smallest of cracks and holes and push itself in between and pinch. Latex is also somewhat sticky, which is why it comes with a coating of talcum powder to help it slide.

In case the talcum came off and you found that the inner tube were sticky, you could add a little coating of talcum powder to eliminate this stickiness, which otherwise wouldn’t make it easy for you to slide it smoothly and seat it properly. When seated correctly in its cone, the latex inner tube can be extremely strong, reliable and a great added benefit to your ride.

A latex tube is also known to be somewhat delicate and susceptible to greasers and degreasers, ammonia and solvents, direct prolonged sunshine and high heat, all which may contribute to damaging its properties. These agents, light and heat must be avoided as much as possible.

Now that you know of its great advantages and have taken the additional precautions and care, you’ll certainly feel the difference, enjoy your ride and ride longer!
