These are the best tubes out there, worth the money. They a very thick and hold up well over time. If you don't want flats run these tubes!
Most durable tube on the market. Make sure to use pleanty of babypowder upon intallation to avoid chaffing later.
I bought these not realizing how thick these tubes really were. The rubber is much thicker than your average tube. I'm sure I'll get my money's worth out of these bad boys.
I seemed to be the guy everyone laughed at when I got a flat every time we went on the BIG ride. Rocks and rough terrain are hard on std tubes. Flats don't happen any more thanks to this HD tube. Haven't had a flat since I installed them!
Great tube wow it's super thick!
Works great!! Its the only tube to buy If you don't want a flat
This tube was super thick, thicker than I expected. It was difficult to install because it barely fit in the tire. However, it didn't pop upon installation and is still running strong a few months later.
tough as nails
Super heavy duty tube. If you can get it installed without pinching it, it'll last a long, long, long time!
Did the job. LA to Vegas without any issues
Excellent choice for riding in the woods or rocky terrain. Also is a good choice if you're still learning the ropes on changing your own tires.
These are super thick tubes! They hold up to rough riding and terrain. I have yet to ruin one from rough rocks. Did rip one after riding on it for 80 miles as I had a bad rim lock and it eventually cut through the tube. But took it 80 miles to get through there.
This is a great 4mm thickness tube to purchase for the
price but mainly the durability it provides the tires and
keeps your bike running rather then repairing.
If you are tired of flats and changing tubes all the time the STI heavy duty tubes are the way to go.
Super heavy duty tubes kick butt in the desert.
Good heavy duty tube for the money.
Can't beat this XX heavy duty tube for the price.
STI Ultra Heavy Duty Tube - 110-120/100-18 excellent UHD tube priced below the competition. UHD tubes are necessary in desert rocky gnarly terrain and these tubes do the job.
