good for thorns
We have so many of those low laying green plants with the yellow flowers with really nasty thorns along the sides of the roads around here that I have installed the no-flat tubes in all my stuff now. Those thorns are nasty, they don't just pinhole the tire and tube they tend to rip a hole in both. They will even go through soft soled shoes.
The back wheel on my trike feels a little mushy when I have a heavy load on it when one of my trailers is really loaded but otherwise I really like them and have no problems with them at all.
I rode about a 9 mile round trip the other day and pulled 34 thorns out of the three tires on my trike when I got back. I will keep the no-flats!
