MEETLOCKS Bike Tube 700x38-45C Recycle Butyl Solid Brass Stem Valve Presta,1 Pcs Pack,2 Pcs Pack,4 Pcs Pack for Choice

Like Chris said, I bought a two pack installed one in the front tire and it blew after 10 minutes of just sitting there. Installed the 2nd one with the same results. Both failed right next to the valve, so I figured it was on me or the rim....had the rim looked at by someone with a great deal of experience and they said try changing the rim tape but otherwise the rim was fine. Bought two more replaced the rim tape and POP! same issue. Save yourself some money....I changed my review from 1 to to three stars. The tubes still get a 1 but the company gets a 5. I wrote to MeetLocks and explained what happened and they refunded the money without question and within 48 hours. I may not buy that brand tubes again but a company with that level of customer service will definitely see my business again.

These things are tough! Although I had a flat while on a 350 mile bike trip, it was not the fault of the tube. In fact, they lasted quite a while considering running about 120 miles on a bad rim tape job! I'm glad I chose the Meetlocks.

The tube s were fine. The only issue was I was unaware that they sell tubes with two types of valve stems and that Presta was not the type on my son's bike. It worked OK anyway.

Three stars because the other inner tube didn't come with a small holes in it! Note! Tire was checked for remaining nails and piercing objects prior to installing new tube, after new tube deflated I changed it with an old tube that has since still remained inflated. Thus, I rather put the blame on the new bad inner tube, especially since others who've bought this product had similar complaints!

Good price. Had one valve stem break but otherwise been great used in a Surly Cross Check for daily commuting.

Two in the box... the first one went "boom" when I got to about 70 lbs. It burst right near the valve (scared the bejesus out of me!). The second one is fine, no issues yet (just two rides about 80 miles).

Nice tube, love the presta valve, although a bit more work then the schrader valve, and....in order to inflate you will need a a presta valve adapter but once filled and you're up and riding, you can't help but yell out, "Ciao Papa"!

Apparently there are two types of piston valves, short and long, I needed long ones, so I bought a ton of the wrong kind. Oops. User error? Probably.
