MichelinC2 Airstop 26" Presta Tube(Return to Product Page)

I use this product on my mountain bike when I have to put on road tires. Road tires on a mountain bike you ask? This is for New York City's Five Boro Bike Tour. Where you travel with 32,000 fellow bicyclists and visit all 5 boros in 40-44 miles. Some of these cyclists even know how to ride in a straight line. One time I took the tour with my road bike and someone rode into my derailleur. (Er. Sorry he said..), so for this ride I leave my road bike at home. It is sufficiently long and early enough in the season that I didn't want to use my Mountain Bike tires.

This application is uncommon enough that it is hard to get tubes in the correct size. Bike Tires direct had the correct tubes in stock. And Michelin is my favorite brand of bike tubes.

I was glad that I bought them and kept a spare in my saddlebag. I got a failure in my on-bike tube whilst on a training ride. This was NOT a Michelin tube and I had a handy replacement. It failed around the valve and would have been a show stopper if I didn't have a replacement tube.

The Michelin tube worked great. I finished the training ride and rode the five boro bike tour with no problem. I would certainly recommend these tubes.

It's hard to find anything 'super' about tubes, they are pretty much a 'good' product or a 'bad' product. Michellin has the name behind it and the tubes are well made and priced right.

Needed new tubes when converting my MTB to a roadie. The C2 Airstop is perfectly compatible with the Michelin Protek tires sold through BTD. Have limited mileage on the tubes so far, but the construction and good support of the tire indicates what appears will be a longer term value.

I ride road mostly and see A LOT of tube destroying debris. Tubes is tubes to me, the Airstop is a little lighter than Kenda's standard, both are butyl, Kenda seems more substantial. But I also want to take a moment to talk about the GREAT SERVICE I have received from BIKE TIRES DIRECT. Local shops have disappeared where I live, used to be 3-4 now there is one and they struggle. I've used other online bike shops and they are OK but after a few orders and one product issue I can say BTD is the best. Great products, more choices and a staff that treat you good when there is a problem. Accurate and quick delivery and super customer service ... SUPER!

changed over one bike to road both tires and tubes fit perfect. I am satisfied.

It's amazing they hold air!!!

Had a few flats but it was more due the rim .. Loses very little air..

This is a great product with no issues. I don't trust off brands...go for the real thing!

Tubes of course leak air with time, but these seem to hold air longer than most - less pumping up of the tires

I used with the Michelin Run'r Wild Tires I bought. Perfect Fit no problems with installation.

Just as expected. Good quality tube.

This was used on the rear of my recumbent trike. It gave no problems in installation. In combination with the Gatorskin, it has run flat free for over 100 miles.

I've been commuting on Michelin slicks with this tube and it has minimal pressure loss if any. I would recommend it as a reliable tube. I carry a spare but I think it will be long before I have to use it.

The tubes look very well made and I was surprised how the valve stem is reinforced where it attaches to the tube. So far I've hadn't any problems with them. I suggest that when you change inner tubes, look at the condition and the type of rim strip that you're using. In the past I had a problem with tubes that were splitting on the side that was pressing against the rim. At first I thought it was caused by buying cheap inner tubes so I bought expensive tubes and I still was getting flats. The problem was actually caused because I was too cheap and was using inexpensive,poor quality rubber rim strips. You may want to spend a little more and buy rim strips that are made of a nylon cloth material.
