🚲 CrabTek 2 Pack Inner Tube 700x38C/35C/40C/43C with Rim Strip - Schrader Valve A/V 33L 33MM - Perfect for Mountain Bikes Review

Apparently if you overinflate or pinch the chamber during assembly, the tire will pop very loudly. In the middle of the night the neighbors startled. It was my fault. The product is excellent.

Although the price was great, the first hose burst at the seam after one day. The second inner tube contained slow lead. Ordered a replacement, hopefully good luck.

Both failed and seeped through the seams for days until one failed catastrophically and exploded at the seam. Another broke a valve stem a few days later during a trip. Operating at 90psi, they really are ticking time bombs.

Only received 2 tubes, no rim. The package was delivered undamaged. The strips are more valuable than these tubes, so I was definitely ripped off. No more reply from Crabtek.Crabtek will no longer receive RMB from me.

Although the tube was easy to install, I'm sure every tube will be installed the same way. Unfortunately, the first hose in the kit broke after 3 weeks (light driving). . The second tube was enough for a week. No nails or other sharp objects were found inside the rim and tire that could cause breakage.

Happy with the purchase. In fact, 4 rim tapes (2 pairs) were included. Both rim tape and tubes were easy to attach. So far I've put about 50 miles on my hybrid (27" rims) and it's holding up well. Use my bike for combined road and trail riding. I weigh over 200 pounds so I train hoops. Used to replace an inner tube from a regular bike shop that only lasted 1 day. I would recommend.

This product has some production problems. Valve stems break easily. I thought it was during installation but I noticed the second tube has small cracks on the bottom of the stem. Replacement requested, when replacing there were also small cracks and tears. Too bad the rubber is thicker and looks like a quality product. The crafting process must be revised to obtain this core.
