Weight is every racer's enemy. A few grams can mean the difference between winning and losing. Now professionals and amateurs alike can have the advantage of our remarkably light "Service Course" tubes, which weigh barely 70 grams (in the A1 road version)! Its extremely light weight and Michelin quality are a formidable combination.

Rated 1 out of 5 Blew two new
Bought a pair of these for a TT bike to pair Ultremo tyres, both tubes blew up before I'd started the ride - put 130psi in them but never had any problem going up to 140 before.

Rated 4 out of 5 by PaulRG Dependable, light weight, good value for weight
Have been buying these for many years. I use the butyl version on my normal road/training bike and the latex version on my race bike.
I have found them very dependable - although a couple of colleagues have had the vale weld fail.
If you find that they fail when you hit a bump or pothole then you need to pump them up harder - or buy the normal (heavy weight) version.

After having issues with Conti tubes, I bought a pair of these, forgetting the weight difference, they perform really well, and loose hardly any pressure, whereas the contis would be flat in a week.

Rated 2 out of 5 by LycraLover72 Love/hate these tubes
The tubes themselves are light and compact (so good for spares on rides) and retain air reasonably well. They are easy to repair punctures on. If that was all I had to say, they'd get five stars.
However, I have had to throw out about eight of them over the last three years, and they weren't due to my self-imposed "five punctures per tube" policy. Every one I threw away was due to the tube's valve stem weld failing. You can't patch that.
Michelin, take note—YOU NEED TO FIX THE VALVE STEM WELD! I will continue to buy these, but would swap to another brand with ~50mm, smooth valve stem if it were available. With these reaching the AU $10 mark, they are no longer as attractive as they were. The second-string Michelin tubes are OK (even if heavier), but don't seem to patch as well, and have grooves around the valve stem that degrade the ease of pump removal.

Rated 5 out of 5 by DJdoddy Can't Fault these tubes
I only buy these tubes i use Michelin lithion MK 1s in the summer and put my schwalbe blizzard sport on in the winter.I have gone over glass when i had the michelin tubes on and had no punchers with these so i cannot fault them at all.
You can pay high prices for some tubes but don't be fooled in to buying something more expensive when it's not all ways going to be better in some cases.
You can pay more for cheaper tubes in a lot of places that sell them and they will be a load of rubbish.

Works fine. No punctures....... In my experience punctures are generally caused by outside influences- glass in the tyre, spoke ingress etc

Rated 4 out of 5 by Anonymous Best tubes except...
Bought these tubes and I'm impressed by the weight considering the price. It's great except the valve is not threaded... Personal preference I guess.

Rated 1 out of 5 by Anonymous two punctures in a week
Oh dear. thought these would be good but I've had 2 punctures in a week on the front tyre. Funnily enough both punctures happened when the bike was at home with no one on it the day after riding. No object penetrated the tyre to cut the inner tube and it wasnt pinched as I checked both sides thoroughly. Must be poorly manufactured with a weak spot that just give after a certain time. Pressure was 95 psi. Shall not be buying again.
