## Description

MICHELIN AirStop Tube, 700x18-23mm 40mm Presta Valve

Review: Smooth valve stem is nice feature - What can you say about a tube - it holds air, that's about it. Isn't terribly heavy, hasn't leaked yet, etc. I've never had a problem with these as long as proper air pressure is maintained. Quality seems okay, and price isn't too high. The smooth valve stem is fantastic. Many tubes have a threaded stem, which eats up the rubber seals in your pump & makes it difficult to smoothly disengage the pump without losing much air. The smooth stem on the Michelin tube easily slides out of the pump head, making inflation a breeze.
Review: Great General Riding Tube. - These are great all around tubes. I had some higher performance tubes and they lost pressure pretty quick. Like the name says they are "AirStop" and hold pressure for several days with only a few psi loss. Two things to consider. First they do not have removable stems so you cannot fill them leak stop fluid. I don't like the stuff because eventually it forms a ball in the tube and when you really need it all that happens is they leak a milky sticky fluid that gets all inside your tire. The biggest thing to watch out for is they are non-threaded and just a little smaller diameter than the threaded ones. If you have a pump with a clamp/release mechanism they are fine, but with the push-on type CO2 cartridges sometimes they don't seal well and can leak. Luckily for me I had two cartridges and the second one worked when this happened. If you use CO2 cartridges, make sure it seals well on the stem before you go off thinking you have a spare. I now carry a threaded tube as my spare.

### ⭐⭐⭐⭐⭐ Superb tube - smooth valve stem is great.
*by G***F on September 3, 2011*

I now use these as my tubes for all my bikes. The smooth valve stem has kept me from having a single failure at the valve stem due to stress on the rubber/metal junction during pumping. My pump head slips on, locks down, pumps up, slips off with virtually no loss of air pressure and no stress on the tube at all. I have had them fail as any tube would from severe punctures etc. but I have never had one fail due to poor quality. My favorite tube. I have tried others, none are as good.
