Tuebeless vs TPU tubes

Notices
Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

The primary flats from hitting potholes is pinch flats which don't exist with tubeless, so tubeless is better in that regard. Most of the examples here are hitting a pothole and tearing the tire which is bad no matter what you are using. At that point it's a bit of dumb luck. Most of the time anything big enough that the sealant can't seal will leave whatever tube you are using very vulnerable to a flat the next time your ride over something unless you stop and put in a boot.

My understanding of rolling resistance is that latex tubes are actually the best but delicate. Tubeless is close to latex and more robust. TPU is worse rolling resistance but still better than butyl tubes. www.bicyclerollingresistance.com has tests for all the various configurations.

3 tubes and a Park GP-2 patch kit (which supposedly works according to a poster in another TPU thread on this forum) weigh the same as the butyl tube I carry in my saddle bag.

Are they hard to install? Have you used this brand before? Iíd love to give a couple a try.

Here again, www.bicyclerollingresistance.com tests rolling resistance on a drum, not in real world road conditions. I take their ratings with a grain of salt.

One of the advantages of latex tubes is a plusher ride according to some who use them. A downside to latex is that they lose air faster.

Although drum testing might produce numbers that differ from the real world, I think it still gets the relative results right, i.e. if tire A tests better than tire B on a drum, A also tests better than B the real world.

The Ridenow TPU tubes are the first and only brand my friends and I have tried. They are not hard to install but because they are so thin you need to be careful not to pinch them with a tire lever when removing the tire. So far we havenít had a flat yet. At under $10 per tube itís worth a try. One drawback is they only come in a 65mm valve length for 700c tubes. If you have deep section rims they may be too short. We havenít tried using valve extenders yet - the valve cores are not removable.

You are right, but I think real world really benefits tubeless where the lower tire pressures help on rougher surfaces. Youíll never convince naysayers without the standardized testing though.
