Continental Conti Valve Extender (Pack of 2)

Didnt screw flush down on latex tube, but seals just fine. Tool included is nice.

Theyre great. I put plumbers tape on them as extra precaution, but Im not sure its necessary. I use sealant in my tubes and therefore buy tubes with removable cores for my deep dish rims. Anyway, these work great!

Great for continental tires

It looks good, but it doesnt fit any tire.

These are the valve extenders to get. Works perfectly, and light weight as well.

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.

During the final lap of the Cedar Hill Race Festival in Cedar Hill, TX, the valve extender on my rear wheel failed, causing me to lose control and crash out myself and one other rider. Luckily the other rider is ok but I wasnt so lucky and ended up with a sprained shoulder and possibly a torn ACL (hopefully just a sprain). I have a video of the crash and you can see the tire instantly lose air, causing me to lose control and I have a picture of the tubes stem with whats left of the valve extender still screwed into the stems threads.

Exactly what was needed for the deeper Zipp rims. Removable valve core tubes and these extenders make everything so much easier. I wish you could buy different lengths in a set, but this was a huge improvement. 48mm valves on the tubes and 60mm extensions fit the 808 rear wheel well but are long on the 404 front wheel.

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.

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