Fat Bike Tube - Schrader (Auto) Valve - 26 X 4.0 - Two Pack

Looks like some quality tubes. One worked as expected and one was a challenge. Went to install the first tube. Could not inflate with the floor bike pump. Ran the shop air compressor and it inflated the tire. Even with the valve removed the tire would not deflate. Poked around with a probe and got it to deflate enough to get the tube on the rim. Tried to inject Slime into the tire and could not get the Slime into the tire. An hour or so of fiddling with the tube and getting it off the wheel the other tube seemed to work ok. It seemed to have similar problems but I was able to get slime in the tube and installed on the wheel. So far the tube is working but I hope the problems like the first tube don't show up. Will see how this tube lasts and if problems with it happen when it comes time to change it.Updated 9/24/19 Based on the quality of the tubes (other than the hiccup with the first tube) and the response from the seller, this is a 5 star product. Upgraded from the original 3 star rating. The tubes are heavy duty and work well in my fat tire e-bike. The seller had an immediate response when he found out I had a problem with the tube and made it right "right now"! When they say its %100 guaranteed they mean it. The problem was resolved immediately without making the customer feel like a dummy asking for help with the product. Based on the product quality and customer service, its a no brainer to buy from them again. With all the off road desert riding I do, more tubes will be needed sooner rather than later.

Nothing special about these tubes. They aren't extra thick for puncture resistance, they aren't filled with slime or any sealant. Just basic tubes. They're the best price I found, getting two of them for the same price a lot of brands charge for a single unit. They arrived quickly, installed just like any other tube, and have been holding up fine. I'd definitely buy them again, though I hope that won't be for a while.

Quality of the tubes is great. Very thick, and worked great in my 26 x 4.25" tires.Warning if you plan on using sealant in the tubes, like Slime, Stan's, etc. The hole at the bottom of the valve stem might be partially blocked by some rubber during manufacturing. It's no problem getting air in, but adding slime was challenging on the tubes I received. I did find that running a drill bit down the valve opened up the blockage and allowed the Slime to flow.Customer service is excellent! Eric responded immediately when I had concerns about the issue and made sure I was satisfied.If you don't plan on adding sealant I'd recommend these 100%. If you do plan on adding sealant just be aware it could be tricky.

Good tube! These have a metal stem there well vulcanize to the tube. I typically do not like capturing the valve stem with a jam nut. However, this tube seems to have the valve stem well attached to the tube so in this case, I’m liking the idea of a captured valve stem with a jam nut.The tubes appear to be a better quality inn, slightly thicker than the crappy tubes that came in my fat tire electric bike.Only thing that can be better going forward is for them to offer a tube with an extra thick outer shell on the tread position to be more anti-puncture.In general, this appears to be a quality tube compared to Chinese crap.

So these came in fast as usual with Amazon and we're exactly what the description stated. I go through a lot of bike pumps and these work great.

Sturdy inner tube, great price.

Got my fat tire ebike up and running again! So far I have about 35mi on the new tube and it’s working fine. No issues with fitting it in the 26x4” tires. My only gripe is that I wish they were individually wrapped as I don’t plan to use the second one until I need it. I believe the rubber will last longer if sealed.

Not sure why I even bother with Amazon reviews anymore. The suppliers can’t contact a bad review to make right. And Amazon makes a tik every time you do a return. Ugh, why is e-commerce buying so hard. Bring back the Kmarts and shopkos.One tube leaked on a ride, too much work to even bother retuning. Other tube seems fine. 50/50 shot at having one good tube.

Parfait aucun mots a dire.

Product was accurate according to detail.

Seems to be the right size
