🚲 ZOL Mountain Bike Bicycle Inner Tube 26" x1.95/2.125 Presta Valve 48mm – Reliable and Durable Tube for Optimal Performance Review

So the product leaked due to a manufacturing flaw and had to be replaced. I mainly ride my bike for short trips on city streets. For comparison, the tube that came with the bike lasted 14 years. The front pipe is original. This takes less than 20 trips. The company will not replace.

3 tubes seem great (not tried yet) but 1 out of 4 had broken stem threads. Unfortunately, I only noticed this when I put the tire back on the rim. Had to start over to remove it and use a different handset. See photo at the beginning of the thread. DOUBLE CHECK BEFORE INSTALLATION AND SAVE SOME TIME AND EFFORT.

I bought this tube simply because it looked like the best deal on a stock mountain bike tube on Revain. I wanted a Presta stem, not a Schrader, so I went with this tube. I have no problems with this tube. HOWEVER, PLEASE NOTE that there was no set screw on the stem to hold the stem against the rim. I'm not complaining as I had about 100 in my garage and only used one. But it's worth checking out if you're interested. A simple tube that gets the job done.

My e-bike tends to bend and eventually break stems, both Presta and Schrader. The thicker the hose, the worse this effect becomes. This tube is very thin so I use an insert to keep spikes, screws and nails out, but the advantage of an e-bike is the flexibility of the stem. Even if the engine torque twists or deforms the stem, it doesn't break that often. Also, this hose doesn't need more than 40-50 pounds before it really starts to deflate. £30 is really low but I found it worked well with this

I bought these to have spares in my bike saddlebag. I only had an apartment a month after buying it. The tube was taken out of the box and placed in the seat pocket - never unrolled or exposed to anything. I stumbled across the path and went to use this hose, unwrapped it and started blowing some air to shape it and it had a factory hole that rendered it unusable. And now Revane says the return window is closed - not cool. I recommend anyone who buys them to inflate some air on arrival to make…
