The tire sealant hasn't been replaced in 2 years and I couldn't justify spending money on sealer just to turn around and buy more in a month or so when I get tires. I already had to put a tube in the front and recently the rear was needing to be pumped up daily, so I looked for the least expensive tubes I could find to keep my bike on the road in the meantime. These tubes were the best deal I ran across, and the tire levers were a great bonus. But wait.....there's more! The little valve stem tool was also a nice touch. I have no use for that on a presta valve, but they'll be handy to use for shrader valves for sure. I split the levers up and paired them with 1 each from another pair I had so I'd have a valve tool in each of my 2 bike kits. The tube itself is pumped up to 35psi and so far I've ridden a couple miles on it and all is well. Before installation I also pumped it up a bit and looked it over very closely since there were a number of unfavorable reviews. It appeared to be of good quality and gave me no reason to believe it won't last for a reasonable amount of time. I think at least a portion of the less than stellar reviews may be due to other factors having nothing to do with the tubes quality. I do know that rims are built to use either a presta, or a Schrader valve, and to my knowledge there aren't any that are specifically made to accept both. If a Schrader is crammed into a smaller hole meant for a smaller diameter presta valve, well, I think the outcome is pretty obvious. A presta left to slop around in a bigger Schrader sized hole will likely cause undo strain around the valve and cause problems as well. I've seen many new tubes damaged due to pinch flats caused by the tube being pinched between the tires bead and the rim, then inflated. Some rims have burrs and imperfections that go unnoticed and can puncture a tube. I only mention these things because from what I see, these tubes are of pretty decent quality. I suppose if my opinion changes, I'll promptly change my review, but for now I think 5 stars is a fair assessment given that even the unfavorable reviews mention great customer service and an effort to make things right on the manufacturers part, that's gotta count for something. I should also mention that I pull a heavy trailer and am pretty hard on my bike as it's my daily means of transportation. So far, so good. Review: Good price and quality - Works as expected. Replacing Kendra inner tube that developed a slow leak which I could not find the source. ## Features - Presta Valve – The heavy duty reinforced rubber base and extremely robust 48mm FV Valve prevents shearing off while cycling - User Friendly Innertubes System - The bike tubes are designed to fit all types of mountain bikes with wheels of 26" and a tire width of 1.75 to 2.125 - Puncture Resistant - Thorn resistant specialized tubes have been tested to ensure highly resistance to punctures - Tire Lever Pro Tool Kit - Quick and Easy Installation, pry and close ties in with little to no effort, reducing the inner tube installation time by as much as 50% - Solid Thick Butyl Rubber - Excellent resistance to ozone cracking, weathering, or aging ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09B856Y2R | | Best Sellers Rank | #7,470 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #40 in Bike Tubes | | Bike Type | Cruiser Bike, Mountain Bike | | Brand | Ultraverse | | Brand Name | Ultraverse | | Compatible Tire Width Maximum | 2.13 Inches | | Compatible Tire Width Minimum | 1.75 Inches | | Customer Reviews | 4.4 out of 5 stars 1,215 Reviews | | Included Components | Instructions, 2 inner tubes, 2 bike levers | | Item Diameter | 26 Inches | | Item Type Name | Bike Inner Tube | | Item Weight | 0.45 Kilograms | | Item Width | 2.13 Inches | | Manufacturer | ULTRAVERSE | | Manufacturer Part Number | 102 | | Material | Butyl Rubber | | Material Type | Butyl Rubber | | Model Number | 102 | | Size | PRESTA 26'' x 1.75/2.125 | | UPC | 677222545857 | | Valve Length | 48 Millimeters | | Valve Type | Presta | | Warranty Description | Warranty covers defects in workmanship and materials for all parts of the product. | | Wheel Size | 26 Inches | ## Product Details - **Brand:** Ultraverse - **Item Diameter:** 26 Inches - **Material:** Butyl Rubber - **Valve Type:** Presta - **Wheel Size:** 26 Inches ## Images ![Bike Inner Tube, 26/27.5in x 1.75-2.125, Presta Valve | Rubber tube, fits mountain, trail & all-terrain bikes, 2 pack - Image 1](https://m.media-amazon.com/images/I/81pzXUVlPVL.jpg) ## Available Options This product comes in different **Item Shape, Size** options. ## Questions & Answers **Q: How big are the tools included in the set?** A: Hello, The Multipurpose tools are 120mm L 20mm l - 17mm h or 4,7 inch L - 0,78 inch l - 0,66 h **Q: I have a 650b 2.0 tire. Will this tube fit my size? Which one should i choose?** A: Hello, The 650b means that you own a wheel of 27.5" in diameter. The other measurement symbolizes the width of the tire. We recommend you buy the Presta 27.5" X 1-75/2.125 inner tube size. This will cover both your diameter and tire width. Thank you, Ultraverse Team **Q: Do the presta valves have removable cores?** A: No. The cores cannot be removed. They have a small part that unscrews to add air, but they do not come off. **Q: Is presta stem removable?** A: No, it is fused to the tube. If you want Schrader, there are adapters. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Seem like fine tubes so far, tire tools are cool too. *by L***. on November 5, 2022* I normally run a tubeless set up, but my tires are very worn right now and I plan to replace them when I have the extra cash.
