Less flats, more fun.

Ward off flats with the Michelin Airstop Butyl Road Tube. The thicker rubber adds a bit of weight, but makes up for it with increased flat protection over super thin and lightweight racing tubes. These tubes are great for long training rides and daily commutes where a flat tire could seriously impact your schedule.

  • Thicker rubber
  • 700c/35-37 size
  • 40mm Presta valve stem

Unanswered Question

do the 35mm tubes have a smooth or threaded valve stem?


A tube is a tube

  • Familiarity:I've put it through the wringer

I needed a new tube for my bike and this one caught my eye because of the price. All I can say is that I put it on my bike and forgot about it. I haven't needed to patch or replace it yet. Now what more could you want out of a $7 tube?


Great price

  • Familiarity:I've used it several times

These tubes work as advertised, if your a weight weenie they're not for you. Great price for a quality daily commuter or training tube.


Just what I wanted

  • Familiarity:I've used it several times

Exactly as advertised, and just what I was looking for. Better prices than I could find elsewhere also.


Great daily rider tube

  • Familiarity:I've put it through the wringer

I prefer the Conti race tube for it's light weight but these are a close second. Yes, they are a little heavier but that's because they are a little thicker. And that means they hold air better and flat less. If you ride rough roads with lots of debris and have frequent flats, try this one-it could be your solution.
