Review: Great value and performance - These tubeless valve stems are very nice. They feature toolless installation of the presta valves by hand into the stem itself. This can also be done via an adjustable wrench because the presta valves have two sides that are intentionally flattened to allow a wrench to achieve grip. They come with two different rubber seals which can sit inside the wheel which was a nice touch. The valve caps are also aluminum and have a rubber piece on them to allow for easier removal and installation when adding or removing air. Overall these are a quality pair of valve stems that do not leak and work well.
Review: Well made and designed - I bought another brand 1st but it would not seal my DT Swiss rims with my Grand Prix 5000 TL tires. It had a cone shaped bung which was a little too wide to seal the stem hole. These stems have two bung options. The block shaped bung fit my DT Swiss perfectly and achieved a good seal. They also are better made than my previous. The lock nut is a little bigger and the rubber washer is wider making it easier to screw the stem on tight. Very pleased.

### ⭐⭐⭐⭐⭐ Excellent product with a smart design feature
*by M***T on September 18, 2019*

I really like these as there is an aluminum lip at the base of the valve, under the rubber gasket. This makes it effectively impossible to tighten the valve so much you pull the rubber off the stem. Its not the sort of mistake you make often, but it can happen. This design makes that impossible to happen in the first place. Worked perfectly with my DT FR560 rims as well as my Weinmann 80mm double-wall rims. A little short with the DT's but still plenty of room to attach an air chuck.
