Perfect fit for going tubeless

These are working very well in my WTB i35 tubeless 2.8 set up, the rubber O-rings are a plus to get that extra seal.

Worked great

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

I have a standard rim and the rubber part was slightly too big to fit in the hole. I ended up tightening the nut really tight and it still seals so it isnt a huge deal. The stems seem solid and durable. Pretty happy with this product. Only knocked a star off because of the fit.

Bought Stans no tubes version, fought them for a week with no luck. I ordered theses and they worked out great for me, sealed up right away no issues. 2 months in now all good.

Product is great, as expected

Includes a nice embedded o-ring in each nut so they never come loose. Helps with seal and prevent scratches, as well. A spare o-ring is included just in case and the valve core tool is a must have. Great size that fits almost any rim. This will be my go-to from now on!

I should have read all the reviews. Like several other reviewers, after setting up my new tires and wheels, and installing sealant, these valves leak at the drilled rim hole. They dont seal properly. Big mess to re-install my tubeless tires with old Stans valves which fixed the problem. Mistake to buy these to save a few bucks. Stick with name brand components. Not at all sure about all the positive reviews on Amazon. Read and believe the negative reviews!

Converted my Rockhopper rims to tubeless and these seated well and havent leaked at all so far. Easy to install, arrived on time, no complaints. Cant comment on durability yet but so far Im happy.
