Kenda Standard 700c Presta Valve Tube

I own a Specialized E-Bike and I had a tube failure. This was the closest fit that I found on BTD's website. I compared the tube to the failed original Specialized tube on the bike and it was very similar in build and weighed the same. The 700, 45-50 size is perfect for the 700, 47 sized tires on the bike. The threads on the Kenda tube Presta valve are 60 mm whereas the Specialized tire came with 40 mm long threads. It is a minor, visible difference.

The original tire failed I believe due to a faulty, removable Presta valve. The failure mode was explosion.

I intentionally sought a different brand of tube due to the failure even though I believe Specialized makes a great bike. The original tire was a 700, 32-50, 40 mm. Since Kenda's size was the narrow width band of 45-50 I'm hoping this may be helpful in avoiding another problem. So far, 2 months later no flats or problems.

The tube worked exactly as advertised. No leaks & no problems.

thanks

They hold air! Reasonably priced makes it easy to stock a few spares.

Good tubes and competitively priced

I bought two tubes, and one came with a hole in it. But that's on me, I've bought enough tubes to know you should always buy more than two. To their credit, BikeTiresDirect gave me a quick refund.

I bought two tubes to replace old ones. I like the long stem. The tubes look hardy and solid. Installing them was easy and I like the value for the money. I'll be ordering more.

I use these tubes in Continental tires and haven't had a failure yet. I can ride a week before I feel the need to top off the air pressure. I usually ride at 75psi.

had a couple of other Kenda's fail where the valve stem meets the rubber. They lasted 10 years, but both failed within a week. Hoping for better with these. Not a lot of choices in the tube market.

Used in a classic bike restoration

Able to remove core to squirt 2 ounces of SLIME. Usually gets me back home.

I've noticed over time that Kenda tubes seem to last longer. I've re-used them occasionally with new tires, and they're often fine.

Good value. Continental tubes are lighter but my last batch of them had 3 bad valves so using the Kenda

These tubes are nice and light, but I was pleasantly surprised at how compact they are (in comparison to other quality brands) - great for fitting my small saddle bag! And as always, a great price through biketiresdirect.com.

This is my goto bike tube. I have used Kenda tubes for years.

Discounted commodity purchase. Air loss at about 2%-3% daily. If using long stems on shallow rims, be sure that value stem is secure or some flats will occur at valve base. Have patched and the repair provided a lasting seal and a useful tube. Many punctures seem to happen near a seam, so patching is useless.

Work well easy to install and price was good

These tube were factory fresh not bad or dry like some you find at a cheaper price

These Kenda tubes are very reliable and a great value for the price. I would buy them again.

Solid Experience. A totally fine tube. I covered it lightly in talc and rolled it up good. It lives happily in my saddle bag in a plastics baggy.
