MichelinA3 Airstop Presta Tube(Return to Product Page)

What can you say about a tire tube? It holds tire pressure

Great tubes, got about 500 miles on them, not a single puncture. I also noticed they don't leak air as much as standard tubes. Less topping off. I did notice they were slightly heavier than standard tubes...

It's always a crap shoot when I order new tubes because I don't have to buy them that often. I commuted for years on the stock Bontrager race lite tires that came on my bike. I never changed tubes and I never changed flats. Those tires are TOUGH! But, they are really hard and narrow so I changed to some wider tires this year and the first set of tubes I bought with them were some no-name bike store tubes. The goat-heads made pin-cushions of them in a week! But with these Michelins, I have yet to have a low tire, let alone a flat. I checked the air pressure at least once a day the first week and checked it once a week since then and have not had to add any air. Heavier to be sure, but I needed more training weight anyway ,-)

I have around 200 miles on these tubes at the time of this review. Installation was easy, valve and keeper nut seem of good quality, and so far the ride is great. I run my bike with 70 PSI of air in the tires and over a couple weeks I haven't really lost any PSI of pressure when I put a gauge on.

I run them with tire liners on city streets. (lots of road hazard here) I have not had a flat for 4-5 months. I ride 75 - 85 miles a week .

I would definately recomend this tube.

Have been using these tubes for a few years now, they hold up pretty well. I ride 1,300 mi. a year, mostly on the road, still get one or two flats a season, but that might be in part to well worn tires. They hold air pressure much better than an average tube, I always try to keep one of these on hand, but last year I had a flat and the bike shop put one of their tubes on the front wheel. I noticed after a couple weeks the wheel with the Michelin tube will have 10 lbs. more air in it than the bike shop tube.

I love these tubes ! I ride around town along our local bike trails that extend for nearly 100 miles, and when I go out, I don't want to have a breakdown. While these tubes are thicker and a little heavier, I have never had a hole nor have I ever had a seam separate. It's a lot more fun when you go for a ride to actually ride and not have to stop to repair a flat, AND, they hold air pressure for a long time. I also go off road along snowmobile trails through the woods when we go camping, and even riding through briars and raspberry brush, have not had a flat. Buy these tubes for peace of mind.

Michelin tubes are used in each of our familiys bikes. Years ago I transitioned to Michelin for their durability and have no regrets. Quality tube at an affordable price. Puncture resistant and hold air longer than other tubes Ive used give me confidence on all terrain. I ride with Michelin tubes and tires.

I use these tires on my gravel bike. I ride about 22 miles each day. Initially the tires were very stiff and cornering felt uneasy to me. After the first 100 miles, this effect was completely gone and corners nicely now.

Here in Arizona we have to deal with A LOT of thorns and goat-heads from trees and plants are really hard on tirestubes. I've got over 300 miles on the tires now and not one flat tire!

Have ridden daily since receiving the product, no problems whatsoever

Short fides

Bought 2 of these tubes. First one split at seam. Second got small pinhole, slow leak so does not seal

or stop leak as advertised. Just another overhyped overpriced cheap quality tube.

Decent weight, good price. Not a whole lot to say, they are tubes.

I had these tubes on my bike for around 40 miles now. A few weeks ago my rear tire and tube were punctured by a screw on the road. The tube hardly leaked any air and I was able to ride four miles home. The next day when I checked the air pressure prior to repair, there was only a three pounds psi loss from the previous day. These tubes do hold air when punctured! I highly recommend them.

So far, 200 miles inside Michelin Protek 700c x 35mm commutergravel tires, no punctures despite lousy streets, gravel trails and tree debris. Happy so far.

A fairly robust tube - I use these on my '07 Jamis Supernova - the bike I subject to the most abuse - rain, degraded tarmac, dirt, gravel, grass, lunchtime rides from work, and so forth. They usually hold up pretty well. This tube replaces one that'd been on for a couple of years but got punctured when its Clement Xplor Ush was holed by a thorn-sized pyramid of sharp glass.

Good value tube. Serves its purpose well.

Great replacement tubes and easy to install part. Feel confident in the michelin brand as always!

This tube is not thorn resistant.

The Michelin tubes are the best quality. They are my go-to tube.
