Continental Conti Valve Extender (Pack of 2)

Great !!!

Does its job well. It fits perfectly and holds air.

I installed these because I have 88mm deep carbon fiber wheels. There is absolutely no air leak, just make sure you use teflon sealer tape. I have used 60mm length version with 80mm valve inner tube but I could use the size smaller I guess (40mm) , but it is ok.

These seem great in theory, but they only seem to be compatible with Continental valves where the valve itself screws out of the valve stem. Trying to mount these on a Vittoria tubular tire in a deep section carbon rim just depressed the valve and made me lose all the pressure, yet wouldnt even thread onto the valve.

Screws into Zipps tires easily and accepts the valve just as easy.

First off I want to point out that these didnt work for me as I thought they would have. I was setting up 50mm carbon rims, tubeless, forgetting the fact that I need the stems to be fastened to the wheel. These are not threaded to receive a holding nut and can easily be pushed into the rim causing air leakage. However, as a product these are a much better option than using extenders that screw over the presta core, where it is hard to check pressure with a standard gauge and needing to stick a piece of wire or spoke down the shaft the release air. The presta core screws right in to the stem allowing to easily achieve the a fore mentioned tasks. Definitely use a little Teflon tape on the threads before screwing into valve stem.

Before you buy this product make sure you can remove your valve tip or this product is useless.

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.

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

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