Continental Conti Valve Extender (Pack of 2)

Work but they leak like crazy.

Go big go latex! Use these get less flats and go low pressure

Didnt screw flush down on latex tube, but seals just fine. Tool included is nice.

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.

Really complements my Enve Wheels, these look and work great.

This is a terrific product. My wheels have deep rims, and the tube for my front wheel only comes with a 40mm valve stem, which makes it difficult to get a good seal with the pump. I bought the 20mm valve extender and installed it with no problem in about 10 minutes. As suggested in several Youtube videos, I used a little bit of Teflon plumbers tape on the threads to ensure a good seal. Now, the pump engages with no problem, and the valve does NOT leak at all. I should have done this a long time ago.

Great for continental tires

Work great to extend valves for Zipp 808.

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!

Works really well to bring that short tube valve out far enough to actually put a pump on it!
