Your pump will become lonely.

Far more airtight than latex inner tubes, Butyl tubes won’t require you to reach for your pump before every ride. Michelin Aircomp Butyl Ultralight tubes weigh just 80 grams and offer confidence-inspiring durability on the open highway. These also come in three valve stem lengths—40mm, 52mm, or 60mm.

Here's what others have to say...

These say they are for 18-23mm sizes / Will these work with a HED Ardennes Plus SL fitted with a 25mm tire (which swells to maybe 27-28)?


Using these with 25mm tires and wide wheels will open yourself up to problems. It may work but is not ideal. Any benefit from these awesome tubes will be negated by flat problems.

Has anyone used these with 25mm tires?

You should be just fine to use these tubes with 25mm tires.

Hey Matt, thanks for your answer.

I actually went ahead and I tried this tube with 25mm tires(GP 4000S II). I have about 50 miles with the tube, so far so good!

It is a good tube

  • Familiarity: I've put it through the wringer

Have used these for many years. I appreciate the non-threaded, smooth valve stems (more aero? haha). They weigh in just fine. Never had any issues.

I like em.

  • Familiarity: I've put it through the wringer

Consistent high quality. Non-threaded stem. Light weight. 75 gm actual for 40mm stems for the most recent ones I got. Compact in the saddle bag or jersey pocket. Not significantly more prone to flatting than heavier tubes IMO. I wish they still made them with 35mm stems. They usually have nickle plated stems but I have gotten some with plain brass (as in the current picture), which turns dark and mottled. Nickle is nicer.

good tube

  • Familiarity: I've put it through the wringer

These are good tubes-dependable with 3 different size options. They pack very easily in a saddle bag as well.

Decent if you need a Long Stem

  • Familiarity: I've used it once or twice and have initial impressions

The biggest advantage to these tubes is that they come in a 60mm stem length. This means if you have deep v wheels or aero spokes it should provide enough length to be able to put air into the tube! Decent tube but I have had better luck with Vittoria's tubes.

Weighs more than they say...

Granted I have the 60mm valve length the weight comes in at 82g.
May seem insignificant bu when you are playing the weight game with bikes and you are getting to the point of paying 1$ per gram saved then it may be a little more susbstantial. Operationally I have had no issues.

What size tube do I need for my SRAM 60...

What size tube do I need for my SRAM 60 wheels? 700x23 but I guess I need an extended stem length .......?

I use 80mm. I guess 70mm is good, too.

Are you going to stock these tubes again?...

Are you going to stock these tubes again? These are the only ones I'll buy, and I'd rather buy from you guys than some other outfit.

Highly Recommended

I love these tubes. What originally sold me on them was the non-threaded stem. I prefer the smooth exterior of this stem for my Silca floor pump. The air chuck will hang on to a threaded stem and sometimes pull the stem out of the tube.
