When I first purchased this product, It did not fit the tire size advertised. I had to use a 26x 1.95 over "Stop-A-Flat"'s 26 x 2.125. Given the nature of these tires, they put an unusual amount of wear on any rim during installation, both Bell and Stop-a-Flat. however, these tires are supposed to be permanent solutions for as long as the tread on one's tire lasts. Since buying this product and needing to put a smaller than advertised tire over it to gain any function of it, It has now become unusable(4-5months). the shape of this product is not correct. it allows for the pinching of the sidewall in a way that both damages the tire and does not provide rim-tire traction. Say, preventing rear brakes from functioning effectively by allowing the tire to spin over the rim.
After I go to use my bike after it has been parked all night, there is a bump while riding every revolution, as if resting on its kickstand cause the foam tire to form a flat spot.
Often while riding and needing to bank a turn or really anything, the tire still feels like riding on a half flat tire. upon inspecting my 26 x 1.95 tire's sidewall, it has become damaged to where if were to keep using this product, one day while riding, this stop-a-flat would tear through and separate from the rim while banking or something. definitely not a confidence booster on the road. besides look in this picture how easily it pushes to the side. often when riding of the slightlyest uneven terrain my Stop-a-flat is floppin around on my tire.
do not like.
Save yourself the trouble and install a Bell no flat from the beginning
Edit: Edit: upon removing the tire to switch back to air while I wait for my Bell in the mail, I took some pictures of what happened to this tube. keep in mind the 2.125 tire i bought to use over this was way too loose so I put a much tighter 1.95 over it instead. after 6 months of sub-satisfactory use this: (picture) is what happened to it. see for yourself.
the only possibility of using this product would have been MAYBE to try putting a 1.75 tire over the 2.125 tube. from the beginning, mine is destroyed
TLDR: bell is tough as nails. Stop-a-flat works by being already always flat
(to be fair i never tried to fit a 26x1.75 tire over the stop-a-flat. how i got it over the bell tire.... idfk)
I am a heavy guy (240 lbs.) and the tires do not "flatten" like I thought they might when I ride.
This application would also be nice for a wheelchair - with the proper sized insert of course.
This is not a "must have", but it will sure make your bike riding a lot less complicated and stressful.

I've spent more than few collective hours each time I get a flat trying to get the 2.125" 26 StopAFlat on my 2.250" treadded bike. Eventally said to hell with it and took it and my bike to the bike shop, just to pay $40 and get my bike and the tube back to be told that because this is a SOLID product these are MINIMUM tolerances for the tread, tread diameter is measured on the outside, not the inside.
There is no way to squeeze it into a tread that size because it just won't fit. So trust me when I say that spending the few extra dollars on a 1.95 is just worth it, because you'll save the endless pain in the ass that was figuring out that buying the RIGHT SIZE product was the WRONG thing to do for once in my life haha.
Lo que recomiendo es paciencia para ponerla, y ayudarse de alguien, hasta ver algún video de como ponerla, y tener un buen rato. Creo que no debería ser tan difícil, pero bueno es lo que hay y a la larga, es una solución para los pinchazos que funciona.
Will make it harder to pedal - not bad but it is noticeable. on my electric bike it cut range by about 10%
Hard to install properly, takes some tweaking as it need to be perfectly centered at high speeds otherwise you will notice a wobble.
Put half the tire on the rim, insert this tube into the tire, then work the other half of the tire onto the rim. Pretty easy, actually.
It's a bit of a drain on the ebike battery but I already knew that before I bought it.
There is a bit of drag in momentum.
