After I made the mistake of ordering the inexpensive tubes for my sons CRF70 I purchased thes STI Extremes. I have changed dozens of mx tires in my day and the less expensive paper-thin ones were pinched during mounting, or were faulty from the start. The STI Extreme takes all the worry out of mounting, and hard riding. I race enduro, and use these tubes. They are thick and heavy, but they are tough! Great Value overall.
It's true to size, good material, and lasts! I usually run tubes at least two tires and the sti hold up great! Plus a fair price!
This tube is awesome, it's the thickest I have ever seen personally and the cost is friendly. take your time to properly install it and this tube will not let you down.
10" tube hasent popped in a month with a 250lb rider.
Definitely heavy duty compared to the tubes I removed. So far they've held up to my bashing.
The tubes are thick and not bad to install.
Really durable tube. No need to question the box! Put it in and it held air all winter without losing any air! I would totally recommend this product to any rider and I would buy it again my self!
Awsome service and the best parts in the business.
A little heavy to shove in a 10" wheel but tuff as nails.
I like how thick and durable this tube is. Without the aid of the Tire Valve Puller it would be difficult for me to get the valve stem through the rim. Thus, only 4 starts for ease of installation. However, the difficulty is worth it to avoid pinch flats from square edges and rocks. Eventually all my tubes will be replaced by this one!
Sometimes it's kind of tuff too not pinch a tube during tire installation. That's where these tubes come into play.alot thicker than standard tubes which means it's more durable. Will buy these until they quit making them.these are a no brainer.
This tube is a must front and back if you are a trail rider. Thickest tube I have ever seen and allows you to run those lower pressures when needed without that fear of pinching.
Great value. Not the thickest tubes I have seen but from a price vs thickness these are among the best value out there! Sick and tired of repairing cheep thin tubes these look like they will outlast the tires!
I ride at times in some pretty rocky trails.Correct tire pressure and heavy duty tubes are a must!
it appears to be a well made tube
First off - the tube *is* extremely thick. When you are holding the tube it appears that nothing could puncture it. However the rubber compound it is made from seems to be more "Plasticy" and stiffer than other Heavy duty tubes I have used. This stiffness & it's heavy weight do make it a bit more difficult to install. We ride exclusively in New England rocks & Roots and I have Had 2 Pinch flats using these tubes. I have since gone back to the Michelin UHD.
The tube is about 2x as thick as a regular tube. It is very heavy deuty. Should last longer and have less pinch flats.
The STI Extreme Duty Tube is a heavy duty tube that can be easily reused when changing tires without worrying about punching it since the tube is very thick.
The discription Extream Duty is no exaageration!!! This is the thickest inner tube I have ever installed in a tire. It's a lot of tube to shove into the tire. I have no worries of sand wearing a hole in this tube. It is EXTREAM!!! Will make you sweat putting installing it. But having a flat will make you sweat more.
