MICHELINAirstop 35 Butyl AV Tube - Black, 34 mm

Obligatory bragging about how awesome I am and how I'm not the average idiot, I've been riding for 100 years, oh and I ultra-marathon MTB race so you can trust this review. Blah blah blah - you get the point: I ride bikes and I know tires/tubes/spandex and leg shaving.I grabbed these tubes for spares as the price of no-name crap tubes at my LBS is approaching $8 - I figured these should be good tubes too, with the reviews I read here. I made it farther than KoldFlow's 1/2 mile; I actually got three times the distance before the tube split near the stem (no nut, no cap, remember, I'm hardKore). Because I'm so awesome, I wasn't carrying a pump or CO2 to inflate a spare tube, so I had to push my bike. Well, summer in Michigan brings back our state bird, the Anopheles mosquito - so I actually had to run 3 miles to get back to my car. I hate running. With a passion. That's why I ride; plus, I can't deny how awesome I look in spandex, or so my mother tells me.Anyway, bottom line is this: I was running 50 psi in a 2.1 MTB tire and the tube failed after 10 minutes of use at the presta valve. Maybe it is a fluke - I'll try another one soon, as I bought three total - but maybe I'll be sure to bring bug spray, a pump and another brand of tube as a backup.

Kind of expensive for a tube that ripped when I first inflated it in the tire. The tire was a Michelin Protek that recommended this tube specifically. I inflated it to 40psi and was working the bead around to get it centered on the rim when it went completely flat. The rip in the tube was about an inch long and unrepairable. Straight to the garbage can. YMMV.

Many of us are urban riders who can get some extra speed on pavement by swapping out the fat knobby offroad MTB tires for high-pressure slicks. Well, those high-pressure slicks require high-pressure tubes, and Presta-valve tubes are great for that.I put onto my MTB 26x1.5" Armadillo Nimbus slicks, and these need to be inflated to 80 PSI. These Michelin Airstop C4 Butyl tubes with the Presta valves are just the ticket. They hold pressure reasonably, requiring me to re-inflate the tire only once every three or four days, and the high-pressure slicks gives me speed that wouldn't be possible with low-pressure knobbies. I'm happy with the Michelin inner tubes' performance on my urban assault bike (urbanized MTB).

As usual, Michelin tubes are really good for what you pay for. This one is not a 5 stars just for the cost, I suppose it could be a tat cheaper.

I built a heavy duty 'vehicle' out of garden cart wheels to move walls on a new construction I contracted to build. I put new tires and tubes on these heavy-duty spoked wheels, and it worked out fine moving walls that weighed in over 300 pounds each.

Not much to say except that they are good Michelin tubes, what's not to like? They fitted my 2.15" Big Bens perfectly.

I needed a presta valve tube for my specialized mountain bike and so far these are working out great. They hold air better than the tubes that originally came on the bike. And they are comparable in weight too. Good job Michelin.

Better than all tubes I've tried thus far by delivering a great performance to weight ratio. They last just as long and sometimes longer than heavier duty tubes but weigh less.

ok
