Product Description

700x35/43C AV48 Self Sealing Heavy Duty Bike Tubes
Life lies in motion.
Life lies in motion.

PRINCIPLE

During riding, when the inner tube is punctured, the self-replenishing fluid in the inner tube is ejected from the punctured hole at the pressure of the outer air. The self-replenishing fluid condenses rapidly at the puncture hole, blocking the puncture hole, thereby preventing the tire burst phenomenon in the riding process.

Life lies in motion.

Does what a tube is supposed to do! I like the fact it has a longer stem than the OEM tube… works much better on a 700C rim…nice n thick, good value in my opinion….

Not the fault of the seller or the manufacture but check to see what type of valve you have. The valves on this tube were too large for my wheel. Could not use this tube.

Cannot attest to the durability as one of them was leaking once installed. I know I didn't puncture it in some fashion while putting it on but disappointing all the same. And it's outside the 30-day return.

Straight up junk. Bought two tubes. One leaked from a cut valve stem immediately, other blew out after three days. Is it really asking too much for you to manufacture quality goods? Best part: Box has a money-back guarantee: "Contact us immediately and we will give you a satisfactory answer or provide a FULL REFUND." Of course there is no way to contact them to collect it. If you buy this product, you should fully expect to be disappointed.
