Michelin A1 Aircomp Ultralight Road Inner Tube

I have been using these tubes for years. I like the threadless valve stems because they do not tear up my pump head. I also like the low weight. I use them on both 700x23 and 700x25 tires. I never have flats unless something goes through the tire. I average about 9,000 miles per year and have gone some years with no flats.

Excellent value tubes and lite weight , no punctures after two weeks of winter abuse on the UK 's potholed B roads

Excellent tubes that are slightly lighter than normal ones. Easy to fit and nice valve too. Only drop one star due to the price although PBK had a good offer on them!

Even though these need air after almost every ride the stems are holding up.

These are really good tubes...are fantastic with the C050 dura ace wheelsets I bought from PBK as well, no need for valve extender.

This is a good quality lightweight Butyl tube it is perfect for training or club racing they are much more supple than the standard 100 gram Butyl tube which equals lower rolling resistance.

I use these tubes because they are light and have no threads on the valve stems. Threaded valve stems ruin my pump head. I use these same tubes through many tire changes. I do put air in every other day.

I've been using these for about 15 years, and keep; coming back to them. They have a threadless valve, which doesn't chew up the rubber grommet on my pump. They are light (actual weight about 77 g),and definitely lighter than most other brands 'lightweight' tubes, and not too expensive.

so far so good excellent ride feel

Haven't needed to use yet but hopefully will be as good as the recommendation.
