Continental Conti Valve Extender (Pack of 2)

Exactly what youd expect. They install easily, and with a couple wraps of Teflon tape they lose no more than 20 psi/week with some Michelin tires inflated to 85 psi.

Works great with my carbon wheelset. Especially a good decision if you have a set of tubulars that dont have exchangeable stems.

When using deep dish wheels this is just the ticket item you need. Word to the wise always purchase removable core inner tubes.

These work great and its nice they come in various sizes to get the perfect look as well as fit for the wheels. No excess air leaks, if it does leak, it is not noticeable, at least no more than brand new out of the box latex tubes. Product is quality and price was also fair.

Well made and don’t leak, also light weight.

Doesn’t leak and easy to install.

This was the perfect valve extender for my Boyd wheels that are 90mm. I was having a difficult time getting the correct air pressure in the tire with the extenders that came with them. I like how the continental extenders allow for the valve to be exposed so my bike pump stays connected when inflating the tire.

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

This work great with deep dish carbon rims. The ridges on the tip also allow a good grip when your filling up with your presta valve pump. Make sure to put on pipe sealant teflon tape before screwing these on for a better seal. This is the 3rd set Ive bought. Also make sure to get the proper length so that you have room to place the pump on your valves stems. I tend to go with a little longer valve extender because I have a 60, an 88 and 100mm different deep rims.
