Easy set up, good product for the buck

As described.

Couldnt get these to seal around the valves on my rims (Alex CXD4s) with Donnelley/Clement USH tires. Tried with o-ring both inside and outside. Wasted literally hours and hours on these valves. Should have just paid the extra 7 - 8 bucks for Stans as I finally gave up and switched to an old pair of stans valves and had immediately better results (still had some minor valve seal issues, but I didnt re-tape after using these stems and I suspect part of it is that these things blew the valve hole out too much).

Great valves for the price! Get these instead of the premium brands!

Worked great

Works great !

Followed BASIC instructions and both leaked air. Did not form a tight seal.

I think these 40mm Presta valves are the perfect length for my MTB. Ive tried other valves that were 46mm and they were longer than necessary. I like that these valves are made of brass and not aluminum because of the added durability of the threads. I use a rubber grommet instead of the o-ring because I feel that when its compressed down it gives a more complete seal. I really like the shape of the locking nut on these valves because it holds the grommet in place nicely. I also like the silver color on these valves instead of the brass colored valves because they match my bike components better. I dont use the plastic valve core remover that comes with these because I have valve caps with the valve core remover made into them.

Its been a month and holding good!
