Pros

Features (thorn-resistant, removable presta valve core)

Cons

Very poor reliability

Other Thoughts

After more than 500 miles of trouble-free riding on- and off-road with factory-installed standard tubes on our new Cannondale Quick CX2 bikes, I decided my wife and I were pushing our luck and purchased four Q-tubes to "upgrade" to thorn-resistant tubes with removable valve cores. During our first ride after installing the Q-tubes, the front tire on my bike suffered a fast flat (fully deflated in under 5 seconds) with less than two miles of use. The failure was determined to be caused by separation between the rubber and valve stem (I have a picture but couldn't find a way to include it with this review). I contacted Modern Bike about the problem and received outstanding support. We concluded that premature failure was most likely a fluke and a replacement tube was provided free of charge. Unfortunately, my rear tire then went flat after about 25 miles of riding, and that flat was also caused by exactly the same failure mode: The rubber separated from the valve stem. With a 50% failure rate with the exact same failure mode, I completely lost my confidence in the Q-tubes product.

StarStarStarStarStar Using these tubes in Fat Bike

by
Ownership: several months
Tech Knowledge: somewhat high

Pros

Using these tubes in 26x4.4” fat bike tires for general trail use. I weigh about 200 lbs. I have had no issue with them and highly recommend if you want lighten up rotational weight, but still want to use tubes. Or even just these as a spare versus heavier tube

Cons

None

Just what I needed to convert 26” fatbike to split tube tubeless

Ownership: a month
Tech Knowledge: average

Pros

So far so good for doing split tube "tubeless" on 95mm fat rims. I'd say I have about 3/4 to an inch of extra on either side that I'm too lazy to trim off.

Cons

Didn't magically convert my chaoyang cruisers into a surly bud/lou combo. :(
