Riding for fun
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.

Great tube
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.

Great Tire, Needs some break in
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!

low quality tube
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.

Tubes Are Excellent
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.

Gravel bike worthy
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.

Fairly robust tube
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.

A little heavy but worth the protection
These tubes run heavier than the latex tubes but are well worth the added flat protection.

The BEST Tubes!
I have a 700c wheel set with the Michelin Transworld Sprint 35mm tires on them, which I also purchased here. These are the best tubes for overall use and commuting. They are light and strong, and have a nice polymer dusted on the outside, which feels great and mitigates the tube from sticking to the rim or being punctured by the tire when being inflated. And even if they are punctured, its worth patching and re-using them, which is better for your wallet and the environment. You just can't go wrong with these tubes so just go ahead and order 3 and you will be set for years. Thanks BTD.
