Continental Conti Valve Extender (Pack of 2)

will be using these with the XLC Thorn Resisstant tubes

They work

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 finally figured out how to use these, sorry for my previous review, it was my fault for not asking.

Works well, requires a removable valve core

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.

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.

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

Excellent quality. You have to unscrew the presta value off the tube then attach the valve extender. Just as easy to pump up the tires as it is with the regular presta valves. I accidentally ordered a size too big for the depth of my wheels but even so, the extenders still look great on the bike.

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!
