Mixed review

Purchased 2 A1 inner tubes alongside Michelin sport tyres (white 700x23) while restoring a Giant Bowery Fmx 2010. I have both tyres inflated at 105psi and ride mostly road (both smooth and rough paved) I'm about 5'7 and weigh under 165lbs. After 2 test rides that were approximately 15km each; I began a 3rd short test ride and had the front inner tube pop mid ride (pedaling ~30km/h) only after 1km. I walked home and replaced it with a spare continental tube I had lying around. Not sure if I got unlucky with a defective tube or I should inflate my tyres at a lower psi (I recommend 92-100psi max) I have not had problems with the back tube since capping the inflation psi to 95psi. Hope this helps ✌️

Michelin AirStop

I tried other Brands inner tubes and usually have to pump tire once a week. I have rode on the Michelin inner tube for 3 weeks and impressed that i did not need to refill the air even once. I test on every ride. This speaks to the valve quality and tube material. Ride is firm without being squishy or harsh.

Quality inner tube

These are fresh, quality tubes. Fit well and inflate easily. Will definitely purchase again.


Inner tube popped after 3 pumps of air. Has anyone had any luck buying an inner tube that hasn't popped? This was my 3rd try.

Quality rubber

These are one of the few tubes that are not made in China. The rubber is of uniform thickness throughout the tube. I have had excellent luck using these. I use the 40 mm for all of my various depth wheels. Each bike is set up with valve extensions of various lengths. The smooth valve stem is a perfect match for carbon wheels

Good spare tubes.

If it is Michelin than it is a great one! Pair them with Pro4 road tyres and it will be easy several thousands miles experience.



great tubes

generally speaking the tubes work and perform as well a any that i have used. Have not put many miles on them yet, but were easy to to install and like the smaller packaging them others.

Good tubes

For me, these are good tubes, not too heavy but durable. I like non-threaded shaft beyond the top part of the valve stem, these allows for easier engagement with my floor pump. The most recent purchase covers up to 25mm tires.


Valve stems could be longer. Tubes have lost 20 psi in two days.
