KendaThorn Resistant 27 Inch Road Tube(Return to Product Page)

They are very thick rubber on the tire side and value for the money was excellent.

This is heavy tube with thick bottom side. A little more difficult to install tire with this tube but not a big deal.

Installed easily due to thickness, so far 520 miles with no flats. It is a heavy tube though, I weighed it at 375 grams. I'm using them for training now and will switch to a standard tube when I ride my century this year.

i bought this tube because i hate flats and people in my town like to throw glass bottles in the road. i haven't gotten one yet. it is a little heavier which is a draw back if you are weight conscience. If you are a commuter on an older bike or just need a little more protection from a tube, you should buy this one.

The stem broke off. I dont know the exact curcumstances as I was not riding the bike at the time, but this is the first time I have ever had this happen.

I liked the thickness of the tube which will make it last longer and more resistant to puncture.

These are nice tubes. They are super sturdy. A bit heavy but thats what you get with thick thorn resistant tubes. I have not had a flat yet either.
