Continental Conti Valve Extender (Pack of 2)

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.

In addition to this extender I tried Bontrager and Origin 8 extenders and the Conti one is the best. It comes in lots of sizes, they don’t rattle, they are easy to use, solid and inexpensive. I just wish they came in black. End your search and just buy this.

Works great for an 808 size wheel when combined with a 80mm valve stem with RVC. No problems. Thank you!

They work

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

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.

Worked well

i bought a set of zipp 808s and needed these to fit over my valves. they work exactly as described and now i dont have to worry about being stranded if i get a flat!

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.

Does the job and it does it well. Needed to extend my 51mm Vittoria latex inner tube to fit my Easton EC90 wheelset and this was the perfect choice. Easy to use and install.
