bought this as a spare for my mavic crossmax sx wheelset......the actual wheels came with a pair of exactly the same setup, and they work perfectly.......i only used it on the crossmax, which are ust wheels, and not a they work for that purpose, not sure how they will work on conversions though.........
it is pricey for what it is (i could get 4 tubes for that price).....but generally speaking, everything UST is pricey....i guess u have to pay for the convenience......

PROS: works, Never leaked, Comes with everything

CONS: Price

Not for road wheels
I've used UST mountain wheels in the past to great success, and these are the right valves for those rims. However, I bought these thinking I could use them on my Ksyrium Elites -- I was wrong. Use the Stan's universal stems instead if you want to go that route. The Ksyriums lack the narrow rim channel these valve stems need to work properly.

Works great on Easton 27
Used these on a set of Easton 27mm wheels. Never even thought of leaking, felt right at home all comfy and cozy. They do have a short mans complex and won't work with my presto air gauge, no biggie, they're tall enough to work with my Lezyne air pump.

PROS: Perfecto

CONS: Mucho Dinero

Work pretty well
I bought a pair of these (each item contains one valve) and used these on a tubeless conversion on my 'cross bike's Mavic Ksyrium Elites. The front tire sealed up perfectly, but the rear would not, and would slowly leak about 20-30 psi in the course of a day. It got extremely annoying having to keep my tire pumped up all day, and I found out that it was due to the valve rubber grommet in the outer rim bed was ever so slightly too small for the valve hole in the rim, causing a slow leak that the stans inexplicably would not seal, no matter how much I put in the tire. I replaced the valve with a different brand with a larger grommet and now it works perfectly. The front (Mavic) valve is still going perfectly strong. It would appear the variances in the rim holes between both rims is the culprit.

However, these valves are nice because they lock into place using a washer. If your rims have relatively small valve holes, these should work fine, otherwise you may need a valve with a larger rubber grommet.

These valves include a full set of fittings for schrader, etc, but will not work for even moderately deep rims. The valves are only about 32mm long and will clear only shallow rims. However, once fitted they don't seem to cause any trouble. You need to make sure you align the valve to the rim bed.

PROS: Seem to work

CONS: Do Not Always Seal, Valve Not Long Enough, Difficult to Install

BEST USES: MTB, Cyclocross, Tubeless Conversion
