Continental Conti Valve Extender (Pack of 2)

They leak. Oh my, now I have a problem. Used them with new Veloflex Roubaix. Sure, everything fit. I even used plumbers tape around the threads for a better seal. But they leak a lot of air. And this is a real pain in the butt because now my tubulars are held down with glue tape. Ill be out $50 if I need to entirely remove the extender and replace with a new one.

will be using these with the XLC Thorn Resisstant tubes

As long as you remember that these work only on tubes with removable cores, these are great. Try them out at home before you ride. Simply remove the valve core, screw these in, and put the valve core in the extender. Voila! They are well made and come with the mini, plastic valve core wrench. If you find a good deal on tubes with short stems with removable cores, these might come in handy, or if you have deep aero wheels that require an extension, these can help. Better to buy the right length stem to begin with.

These are easy to put in and they look nice. Thank you.

Wish they made longer ones! But was able to screw two of these together and attached to my tubular. I have zipp 1080s and by using two of these extenders together I can air up and know my tire pressure too. These allow for you to screw in the valve to the extender unlike many of the simple straw extenders!

Once I understood how to use the included wrench to remove the valve core and screw into these extenders they worked like a charm. I have used two other brands and types and these by far work the best.

OK, so this is my second set (and third) of these continental valve extenders. Honestly, the third set is just a spare in the event that for some reason I need them. I have found that too much is better than not enough. I purchased the first set after I received my deep rim wheels from Flo (I dig these wheels and for the cost, the are quite nice). Flo sent me a set of Silca valve extenders, which broke during set up. I was really disappointed in them and became really disappointed that I couldnt use my wheels the day they came. I did a little research and ordered these. Install was quick and (even though Silca is just a one step process and this is three) this was an amazingly simple install. Rode these for IM Austin 70.3 and had no issues (except a nervous mistake prior to starting in which I flattened the tire by unscrewing the extender). I dont seem to have any air leaks, not any of significance anyway.

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.

Just make sure you buy plumbers tape (about $2 for a roll). Dont trust the rubber washers to hold air in over the long-run -- plumbers table should, though. Although, this isnt specific to the Conti valve extenders -- all valve extenders of this type are like that. ALWAYS BUY PLUMBERS TAPE!

This product is just as described. Nothing to lose here. It will help you with most wheels.
