Ultra Light Speed TPU Inner Tube

Ths tube runs superbly with low rolling resistance and they sound great but they are very fragile. I punctured one tube putting it on the wheel and another punctured 20miles into my first big ride. The supplied puncture repair patches work really well (best I’ve seen for any tube) but you will probably need them!

Tubes are very light and work great. One has been holding air better than the other but other than that very good product.

Feels good in the hand and the stem looks great compared with others I've had. I run latex and carry this as an emergency, so for space and weight I'm quite happy, I'm sure it rolls well too.

These are really light, the feel when riding is similar to Latex tubes. They also pack into my seat bag taking very little space, no need for large seat bags anymore. They seem to be more resilient to flats than Latex and Butyl tubes.
