Tired of getting flats? Turn to Michelin's revolutionary Protek Max Inner Tube.

Thanks to a unique "square" shape and textured surface, tube actually resists puncture better than traditional round tube. This unique design causes the tube to compress, rather than expand, when pieced by a sharp object. A sealant has also been added to increase the "self-plugging" effect at the origin of the puncture.

As an added bonus, the square design also eliminates twisting during installation and holds pressure twice as a long as a traditional round tube, so you can spend less time pumping up your tires, and more time out on your bike.

This version of the Protek Max tube is sized for 26x1.85-2.30 inch mountain bike tires (47/58-559 ISO) and features a 34mm schrader or 40mm threaded Presta valve (removable core). 349g (tube weights may vary).

This tube holds air better than other tubes Ive tried.

I use this on my MTB with Continental street tires. I use the bike on roads, trails and hard pack gravel. I've gotten punctures with this tube but the slime slows the rate of air loss and it's enabled me to get home without changing the tube.

I purchased 4 of these about 2 years ago (2 for my road bike and 2 for my wife,s touring bike). Place them inside Michelin tires and neither of us has had a flat yet. We live in in area where flats are are common occurrence as the trees here drop very sharp spiny thorns.

My neighbors use slimy tubes and slimy fillers and they are consistently fixing their flats.

Goat Heads Be Damned

In my area we have goat heads galore. I average 1 goat heads per 10 mile ride and I make a conscious effort to stay on the pavement. That means I was repairing a tube after or during every ride. I put one of these baby on and, as usual, got a nasty big goat head half way through the ride. When I pulled it out I could hear the air escaping for about 3 or 4 seconds and I thought I was done. But no! It quit leaking quickly enough that I finished the remaining half hour of my ride and it was fine. Didn't even have to add air. From here forward there's only one kind of tube going in my mtn bike tires. And no, my last name's not Michelin -)

This is a great Mtn bike tube for areas with goat head thorns. So far I have ridden 200 miles with out a flat puncture. I have never done that with any other sealants in tubes. I have tried them all !!! I'll post again as the summer months begin.

I use these on the day I went mountain biking and they lasted. I like how it felt heavy duty as I placed them in and no need for extra attachments to pump air into them. They are great, bought them 5 weeks ago and are still good.
