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) ## Frequently Bought Together - Stop-A-Flat Puncture Proof Bicycle Inner Tube - Tragoods Premium Bicycle Tire Lever Tyre Spoon Iron Changing Tool, Bike Tire Levers Premium Stainless Steel Levers to Repair Bike Tube, Best Tire Changing Tool - Slime Bike Inner Tube with Slime Puncture Sealant --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/40402122-stop-a-flat-puncture-proof-bicycle-inner-tube](https://www.desertcart.pt/products/40402122-stop-a-flat-puncture-proof-bicycle-inner-tube) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-12*
