700C Tube Bike Inner Tube 700X18-43C, Bike Tube 700X18C/25C/32C/35C/38C/40C with Rim Strips & Tire Levers- Schrader Valve

Happy with purchase. Actually came with 4 rim strips (2-pair). Both rim strips and tubes went on easily. So far I have about 50 miles on my hybrid (27 inch rims) and holding up well. Use my bike for a combination street and trail riding. I’m 200+ lbs so I give the tires a workout... Used to replace tube from brick-and-mortar bike shop that only lasted 1 day. I would recommend product.

Both failed within days, leaked through seams until one catastrophically failed and exploded on the seam. The other one blew apart at the valve stem a few days later on a ride. Running at 90 psi these really are ticking time bombs.

I only received 2 tubes, no rim strips. Package delivered undamaged.Strips are more valuable then these tubes so I definitely got ripped off. No response from Crabtek.CrabTek will not get any more $Yuan$ from me..

While the tube was easy to install, I am sure any tube would install the same.Unfortunately, the first tube of the package failed after 3 weeks (of easy riding). The second tube lasted one week. The interior of rim and tire revealed no nail, or other sharp objects that could have caused the failure

Apparently if you over inflate or pinch the tube when installing the tire will pop very loudly. Kinda scared the neighbors in the middle of the night. That was my fault. Product is great.

Tire was flat... bought and installed these... Now I'm rolling again

It is an average inner tube.

Fit perfect and was easy to install
