Continental Conti Valve Extender (Pack of 2)

I am sure you, like me, are thinking... do I really need this? I am also sure you, like me, learned that theres a specification on a tire tube that tells you the length of the presta stem. So I regret to inform you... yes its necessary if you, like me, bought tubes with too short of stems and realize it is not worth shipping the tubes back. Super easy to install. I had the Park Tool VC-1 tool but the included little wrench works fine. I used the included wrench to install the main cylinder. All hand tight and havent noticed any leakage. I am almost certain I can use them on the spare tube when the time comes (since I have 3 tubes but only two extenders).

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.

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!). :-)

Great for continental tires

Bueno

Works perfectly with my 88mm wheels. I have 88mm carbon wheels with 80mm tubes. Adding these extenders gave me plenty of room to inflate my tire without the stem extending out to much.

I’m not sure what the issue is but these cause the valve to jam. I’m not sure if it’s by design but it’s problematic. This makes it difficult to let air out.

It looks good, but it doesnt fit any tire.

Look very nice and have nice sealer on the threads. Unfortunately the male part of the extender broke off inside of my tube, leaving me to call an UBER back to thr group ride start. Have had my other extenders for years with no problems, just wanted something new looking. Oh well.

Works really well to bring that short tube valve out far enough to actually put a pump on it!
