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.
Came quick just need to come in box
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.
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.
