Thorn Resist Tube, 26" x 1.95-2.35 32mm Schrader Valve, Sunlite. Mountain Bike, Cruiser, MTB, MTN Bicycles Replacement Tube Puncture Resistent

I'm what every bike shop hates: a broke college student who is too cheap to spend $50-$100 on mountain bike rims/tires that are the same width and are in good shape. I have (improperly) installed these tubes on various rim widths (1.95" and 1-3/8") with mismatched tire widths and have had no issues for about a year. I inflate them to 45psi and they keep their pressure for several weeks. Yes, it's absolutely better to have the right sized rims/tires, but these tubes are great and they withstand the abuse I put them through.

These tubes have been a blessing for me. I ride to work daily, a 16 mile round trip through the streets and the parks. The parks were my main concern as it is extremely dry where I am located and there are a lot of thorny bushes around. The tubes are noticeably bigger and heavier when riding, but to me it wasn't an issue since my main focus was to stop the piercings in my tubes. The tube is significantly thicker and will require patience while installing. The tube will need to be inflated slightly (10-15 psi) then slightly deflated before inserting, this allows the tube to form with ease outside the rim. These tubes can handle 50 -55 psi with ease. Paired with durable rim tape, and puncture proof tires, I'm able to ride on any surface at any tire pressure without worry. Cheers.

WOW great company that stands behind their products. I purchased two thorn resistant tubes. I installed and both held air until I took a test drive. Both tubes became flat after just a 100 yard test drive. The tubes both had leaks around the neck of the fill valve. I contacted the seller and they QUICKLY sent two replacements. I installed these two new tubes but also checked to ensure no pinching of tube took place while filling and closely inspected tire to ensure nothing sharp was popping the new tubes. I also carefully filled the tires to 40 PSI with a hand pump. These also developed leaks in the same location on both front and back tires after a short ride on my Rock Hopper Mountain Bike. I installed my old tubes and road the bike for about 10 miles without issue. I was embarrassed to contact the seller again because I felt the tubes arrived fine and held air but something was causing them to become flat and I had no clue what that was. I included photos and the seller sent a third set from a different manufacture to try and rule out defective product. I then noticed the seller had provided a full refund of my original purchase price without me ever requesting it. I never felt the owner questioned me or my ability to properly install the tubes he was 100 percent focused on making a happy customer every step of the way.I installed one of the third sets of thorn resistant tubes and only changed one variable the amount of air pressure in the tube was increased from 40 PSI to 60 PSI. NO flats after two months. It is my determination that the thicker tube when inflated to 40 PSI did not provide enough surface tension between the tube and the inside of the tire. This condition would allow the inter tube to move and slide within the tire and rim creating stress to the fill neck of the tubes. The bike has a very hard ride with 60 PSI but to properly expand the thicker tube you will need extra pressure when using Thorn Resistant tubes on a Mountain bike.It is easy for a seller to send behind product when thing go well but is quite a different thing for a owner to stand behind something when it goes bad. The seller was off the chart and was very interested in finding a solution when it clearly looked to be something I was doing incorrectly. They never questioned my ability to install the tubes and just stood behind their product even when I am not sure I would have.I can not rate this seller any higher but I will be a customer for life and would encourage others to do the same to support companies that go out of their way to resolve issues when a customer is having issues. Six stars and a customer for life. Thank you Andy for being a class act.Mike from Fairfax Virginia

nice heavy tubes.... ordered them several times....same problem with every one..... valve stem pops off.... keep thinking it was something I was doing when installing..... this time I added 15 psi before installing and could easily see an air bubble under the thin layer of rubber around the valve stem.... then it popped off like my previous orders

These are thick tubes and hopefully no thorns or goat heads go through

They look well built, time will tell.

These tubes are very high quality, very thick and about as thorn resistant as I have ever seen. They are a little heavier than a standard tube, but you will have to decide if you would rather buy a super light tube and be stuck on a trail with a flat, or purchase one of these and ride with confidence. I don't mind pulling around a couple extra ounces so that I can complete the ride. Besides, I ride to keep in shape, so a couple extra ounces is good for me. Cheers!!

Never had a flat with these tubes!! I'd recommend using these tubes with Puncture Resistant Tires! Select the appropriate tires for the appropriate terrain!
