I’m attempting to construct a very gentle modernish street bike and so I’ve determined to check out TPU tubes. Once they first hit the market, they have been simply too costly for me, however the Thinvik tubes have been about $10 every which isn’t so unhealthy. In addition they have steel stems which appear to be an enchancment over among the different choices which have plastic stems, as I noticed a number of opinions on different tubes saying the plastic stem had damaged. Listed here are some footage:

Very gentle, mine weighed in at simply 39 grams. By comparability I’ve a Continental Race 28 tube right here that weighs 140 grams. A 100-gram financial savings with one tube is kind of superb.

Set up
Set up went very straightforward. I put sufficient air into it, so it held its form and put it into the tire. Then I simply put in the tire and tube the identical as at all times. It has been put in and holding air for fairly just a few days now so appears to have gone effectively. The stem is a bit quick for my 50mm deep carbon wheels. I selected the 65mm stem size which my analysis instructed was a superb measurement, however it doesn’t come out of the rim very a lot. Certainly one of my pumps suits on it and the opposite doesn’t. If I needed to I may additionally get a stem extender. However for now I do just like the look of a brief stem so I’m going with it and can simply use the pump that matches, I assume. Oh it does include a very nice-looking cap too.
Trip
I’m nonetheless engaged on constructing the bike so I’ll replace later.
