Continental Conti Valve Extender (Pack of 2)

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.

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.

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!

Easy to use, just make sure your tube has a removable valve so you can add the extender. Reusable and will save you money not having to buy 80mm valves.

These work fine. No complaints. Far cheaper than what I could find locally.

Came in super tiny resealable bag without the the little black tool in the second picture. Will have to source a valve remover tool to add to the kit

use plumbers tape to get a good seal. otherwise works great. Put on 88 and 60 deep rims

With the attached tool, these extensions are a breeze to install

The extenders that came with my Easton wheels were a perfect fit for the hole but these are slightly smaller in diameter so you get that tick, tick, tick when youre riding. You have to put tape around it to make the tick to go away. Continental should make different diameters as well as different lengths.

will be using these with the XLC Thorn Resisstant tubes
