I’m making an attempt to construct a extremely mild modernish highway 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 dangerous. In addition they have steel stems which seem to be an enchancment over among the different choices which have plastic stems, as I noticed a number of critiques on different tubes saying the plastic stem had damaged. Listed below are some photos:
Weight
Very mild, 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 sort of wonderful.
Stats
TPU materials or Thermoplastic Polyurethane. Purported to have among the traits of rubber and plastic, declare is that its extra puncture resistant and lighter. It’s positively lighter.
Steel stem 65mm
700 x 18-32mm measurement
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 a couple of 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 urged was a very good measurement, however it doesn’t come out of the rim very a lot. One among my pumps matches 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 extremely nice-looking cap too.
Experience
I’m nonetheless engaged on constructing the bike so I’ll replace later.
