MichelinC4 Protek Max 26" MTB Presta Tube(Return to Product Page)Add your own review
I thought I would try a different brand of tubes. I had for years used the Slime tubes. But the slime welds your damn valve caps on. I tried these tubes and they are thick and seem real durable. I have been running them for a month and no "Goatheads" have punctured them yet!!!
Not a ton of miles on them yet, but everything about them so far has been great. The quality is notable from the time you take them out of the box. They install easily and do not seem to loose air like most tubes. Just a really nice tube.
Use the tube on a recreational MTB that need to be ready to go for infrequent ride. So far this tube performs well and was easy to install and inflate. Tube is a little heavy and that is fine. I like durable.
Before getting these tubes and matching Michelin Country Rock tires I had two flats in two weeks. With these tubes and tires I've had no flats in 2,000 miles of bike trails, gravel, rocks, and occasional dirt. These tubes are highly recommended.
I rode the bike for a few weeks, then one day come to the bike for my morning ride and tire was flat. Filled it with air and after five miles, it was flat again. Filled it on more time and it has stayed inflated for days! Be patient, be sure to spin the tire after reinflating to allow the green stuff to seal 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.
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 -)
The tube comes with a very small valve to add air, which was not clear to me when ordering the tubes. These do not take a regular air pump to fill the tire. The tube does not come with any adapter to allow filling the tube from a traditional pump. I went to a local bike shop. They had what I needed and would not even take the tubes - free - for someone who may want them. They are filled with anti-leak material and they said that no one wants these. I donated them to habitat. The effort to return these to Bike Tires Direct .com was not worth the effort. These tubes are way to expensive.
Got my first' flat' and it does not appear to be completely sealing - pressure drops again after 24-48 hrs but holds for a ride. My experience with goo tubes is that sometimes you have to refill the tire several times. I also use tube protectors as I ride pretty hostile (desert) trails.
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.
