Fincci Pair 26 x 4.0 Inch 48mm Schrader Valve Inner Tubes for Fat Mountain MTB Bicycle Bike (Pack of 2)

Great quality inna tubes, fits perfectly in my fat wheels.I only needed to use one.The valve is kinda long just incase that may cause somebody an issue.Also they Stay pumped up, so that's good 😃.On the puncture resistance side, welll, it's rubber. Its Not exactly the worlds toughest material so if something sharp sticks into it it's going to puncture none the less. But they are tough, as in, not super thin rubber.Value is great too I would definitely buy again.

Got these to replace the inner tubes of my Engwe E-26 fat tyre e-bike.They fit perfectly and inflated easily. They function great and hold air perfectly.

Good

I had a puncture in my E-bike tire and needed a quick replacement, they are very easy to replace and so far very durable, will update in time for any updates, but so far very pleased with price and the quality.

Bit apprehensive on buying these compared to a "general" brand, but im bowled over! Fincci fits my mountain bike perfect! just make sure you get a look at your wheels to understand which inner tube you need! the quality is outstanding in the way that the valve is placed different and it worked great for my fat tyre mountain bike on the one wheel!

Got a puncher in my rad rhino and the inner tube went egg shape , so repairing it was a waste of time . There's are a better quality of inner tube thicker and most importantly round. Let's hope I don't get another puncher but let's hope it's reparable.

Two quality bike cameras came to me quickly and the next day

All good
