Continental Conti Valve Extender (Pack of 2)

I found this very easy to install when you follow the directions. Ive used the extender on two tubes. For both tubes, the fit seems correct however when attempting to pump up the tire I meet extreme resistance. Pressure gauge on the pump shows inaccurate results and makes adding air very difficult.

Very good and light. I remove a start because I find annoying that they force us to buy 2 when many people have a disc in the back and 808 in the front e.g.

pricey but necessary for deep rims. works great for me. I had no problems or issues. installed easy without problems

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.

OK, so this is my second set (and third) of these continental valve extenders. Honestly, the third set is just a spare in the event that for some reason I need them. I have found that too much is better than not enough. I purchased the first set after I received my deep rim wheels from Flo (I dig these wheels and for the cost, the are quite nice). Flo sent me a set of Silca valve extenders, which broke during set up. I was really disappointed in them and became really disappointed that I couldnt use my wheels the day they came. I did a little research and ordered these. Install was quick and (even though Silca is just a one step process and this is three) this was an amazingly simple install. Rode these for IM Austin 70.3 and had no issues (except a nervous mistake prior to starting in which I flattened the tire by unscrewing the extender). I dont seem to have any air leaks, not any of significance anyway.

Great for continental tires

Best valve extenders Ive ever used. Takes a little more work to install because you have to remove the existing valve core and put it in the extender, but worth the effort. Other extenders that dont have the valve core in them crack at the threads after a short life.

will be using these with the XLC Thorn Resisstant tubes

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

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