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.
These are quality inexpensive tubes. The valve stem is threaded all the way to the base and there is a nut that goes over the threads. This gives you the ability to secure the valve stem in place making installation incredibly easy.
I have over 300 miles on these tubes with no flats. I am using good flat resistant e- bike tires. There is minimal weekly air loss. Far surpass original bike tubes as well as other replacements.
Great tube well made and strong.
Valves are stainless and screw top (presta)
Sturdy. Rubber ring around valve stem to tube are strong and resist flex unlike other cheaper made tubes.
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.
