Good Stuff

  • Familiarity: I've used it several times

Does its job and does it well. So far they've been super easy to use, no surprise, and I might stick with going with these in the future.

Its a pair!

2 valves for 2 wheels! They will fit most any wheel. Solid for the job!

A Little Short But Otherwise Good

  • Familiarity: I've put it through the wringer

These are great and quite affordable! The base seals up and holds sealant just fine and the valve core is of course removable. I like the pop of red on these add to a bike but they may not work with everyone's color scheme. A second, longer length would be nice for deeper section wheels which are common.

No problems with tubeless set up. They work fine. The red looks good.

The aluminum that they are made of is super soft. Pretty sure these are made of cheese, and not good cheese... like craft singles cheese. The knurling on the nut pretty much is non-existent after tightening them down with a pair of pliers. The valve body itself bent after I pulled the cores and put a compressor chuck on it to inflate. Not very impressed.

Does the job and looks good too.

Nice anodized finish does not seem to flake off and the removable valve core makes inflation a breeze.

Does the job

Get some Stan's sealant and rim tape and you'll be running tubeless in no time! The included valve core remover works well. The red anodization is a nice touch and matches my hubs.

This pair of tubeless valve stems will get you running tubeless in no time. To complete the job, get some rim tape and tubeless sealant.

The removable valve cores make setup easy and mess free.
