Best extenders I've tried. Regardless of what brand extender, I always use plumber's tape.

Much better than the valve extenders that fit over existing valves and use a friction lock to open and close the valve. Just make sure you have spare valve cores in case the existing valve core gets damaged or lost during extraction. Also, make sure your tube or tubular tire has a removable core or else this will be totally useless.

Work perfectly for converting carbon aero wheels to tubeless. Use plumber's teflon tape to keep the connection airtight.

I have an older Spinergy wheel on my now commuter bike and was using a set of Lezynes before that both cracked in short order, these work much better so far and seem much better made and more durable.

If you're trying to convert deep-section wheels to tubeless, this is the ONLY way to do it. If you've never used good valve extenders:* Remove the valve core.* Thread these into the valve stem (I also wrapped the small threads with teflon tape), rubber-side first.* Use a stem wrench or needle-nosed pliers to make sure they're tight.* Thread the valve core into the open end.* After inserting the tubeless valve stem into the rim, make sure you tighten well with the locknut, even if you're using the rim strip version.
