These are great inner tubes. I used to get flats about every week, and I haven't gotten one since I put these on! A must buy for urban riding.

Kenda Presta Tube
Works really good and not that hard to put on, only thing that sometimes annoys me is when the presta valve sinks inside the tube and i have to manually pull it out, but overall a sturdy tube.

Great tube
These tubes last a while, they seem to take potholes pretty well too. I haven't switched my tube for a while now and I seem to like these tubes over any of the latex tubes too. I prefer these with the 700x25c sizes for my training as well.
