Can't really review the tubes other than to say I received one that was defective and Western Bikeworks sent a new tube out right away. Excellent customer service. Looking forward to doing business again. Suspect that the tubes will work great. 5 stars for the bike shop....and if I don't edit the review at a later time, assume 5 stars for the tubes also.
So, a pair of these went inside the new cruiser tires I purchased to restore the Specialized Shark cruiser. Look that bike up - it's pretty cool. My daughter loves the look and ride of it with the white Conti retro 26ers.
Excellent tube with a metal stem. I have had problems with rubber stem tubes with high pressure recumbent bike tires. This tube solves the problem and gives me a tube that I can rely on at high speeds and for touring.
Normally have great luck out of continental tires and tubes. But the first tube I had blew up while inflating at just over 40 psi. Had to run to the local bike store and pay twice the price for a lower quality tube. Kind of disappointing, but the other three held.
Bought two of these tubes, $6.99, on sale for $5.41(?), good value at that price. They come with the schrader hole washer, that sells for $2 at other bike shops. Still a good deal at $6.99. Very easy to install and have held up great for the last 100 miles. I commute from Vancouver to Portland, 14 miles one way, five days a week.
I got these tubes to match with some Continental tires bought at the same time. While I was installing the first tire, the tube blew out at about 50 psi, about a 4 inch long split. Could have been pinched, or a one in a million defect, I don't know. I never had a tube blow out like this before in 40 years. But since this was for my wife's bike I switched for some older Specialized tubes I had on the shelf that were a bit thicker rubber.
I run 1.5 semi-slicks on my mountain bike for road use. The standard 1.75-2.1 mountain tube does not install well and pinch flats. This tube solves the problem. The rubber thickness is a bit more and more reliable against flats. I have over 15 bikes and I am convinced the Conti tube is the best! Rumor has it that all tubes come from the same factories in China but for whatever reason the Conti tubes are the best quality, easy to install, but most importantly reliable. Get them!
The threaded valve stem is a cool idea and helps make it a little easier to get some pumps latched on to the stem when there's no air in the tube. I've been using the Schrader version. Gave good volume to the 2.2 tires I used and fit done in the 1.95 as well. I've run em at pretty low pressure on some rooty and rocky trails without any pinch flats yet. This is after a couple hundred miles of use. I feel confident using these tubes and will buy again.
My old tubes no longer held air for more than a weekend, plus they had Presta valves. I can use my air compressor now that I have tubes with Schrader valves. Competitively priced.
