Continental Conti Valve Extender (Pack of 2)

Best valve extenders Ive ever used. Takes a little more work to install because you have to remove the existing valve core and put it in the extender, but worth the effort. Other extenders that dont have the valve core in them crack at the threads after a short life.

These are great. Easy to install, leak free.

Doing what theyre made for, no issues would buy again. You need a removable presta valve to run these

Honestly, I shouldnt review these, because I never actually USED them. They are light and seem very well made. Others have reviewed them well. My problem is these require you to start with tubes with removable valve cores... simple enough, but where the heck do you get them? this turned into what I thought was a simple solution into... too complicated to race with argument. I gave up and bought long valve stem tubes to use with my 60mm carbon rims.

I was looking for an extender for my presta tubes. This was not it.

Originally, I just tried screwing one of these puppies over the presta valve of a tire on an aero wheel, but that didnt work well at all. Prepared to award this seemingly miserable product a single star and a nasty review, I happened to glance at the DIRECTIONS, and realized the valve was to be disassembled BEFORE attaching the extender, and that the black plastic piece in the packaging was a wrench intended to accomplish this very purpose, and not, as I initially perceived, a roach clip misplaced by a Continental or Amazon employee. This is a great product that works wonderfully, even if the wrench looks like a piece of drug paraphernalia.

Dont waste your money and give yourself aggravation using any valve extenders that dnt have this feature of actually moving the valve. The ones that just screw on to the end of your valve and rely on pressure to open the valve are a royal pain in the butt compared to these guys. Never had a failure with this brand or its harder to fine equivalent from Zipp. Multiple failures with other extenders that close the valve or dont seal wells etc. Get these and give yourself some peace of mind. (Youll need to buy tubes with a removable valve core, which cost a couple bucks more...but youre riding Zipps or some other expensive wheel if you need these, so quit complaining about a couple bucks for a decent tube!). :-)

Conti quality. Unlike other reviewers, I did not have any issues with getting them securely attached and with no leaking. Another brand required pipe dope to keep from leaking, these did not. I use them with Conti tubes, so maybe that’s the reason they work well. They do the job they were designed to do.

I found this very easy to install when you follow the directions. Ive used the extender on two tubes. For both tubes, the fit seems correct however when attempting to pump up the tire I meet extreme resistance. Pressure gauge on the pump shows inaccurate results and makes adding air very difficult.

I used these to help clear my 80mm carbon wheelset. Its worked excellent so far, and they held up through the ironman races I did. No air leaks.
