Continental Conti Valve Extender (Pack of 2)

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

Excellent quality. You have to unscrew the presta value off the tube then attach the valve extender. Just as easy to pump up the tires as it is with the regular presta valves. I accidentally ordered a size too big for the depth of my wheels but even so, the extenders still look great on the bike.

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.

Just make sure you buy plumbers tape (about $2 for a roll). Dont trust the rubber washers to hold air in over the long-run -- plumbers table should, though. Although, this isnt specific to the Conti valve extenders -- all valve extenders of this type are like that. ALWAYS BUY PLUMBERS TAPE!

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!

I just return valves. because it doesnt fit for Michelin AirComp Latex Tubes. however this extenders are high-qulity

It would have been better to buy the right size for my tubeless stem, but my LBS only had 44mms. I had enough bite for a shallow air chuck, but it would be too short using others an unfortunate oversight when I went on a trip. These stem extenders are just the right length without looking stupid and work better than the extenders where the valve does not need to be removed. I did use plumbers tape to make sure I had a good seal and had to re seat the tires in order for me to inflate them after installation so if you are planning on using them make sure you have a compressor or good pump or you will need to take a trip to your LBS.

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.

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.

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