Continental Conti Valve Extender (Pack of 2)

Originally, I just tried screwing one of these puppies over the presta valve of a tire on an aero wheel, but that didnt work well at all. Prepared to award this seemingly miserable product a single star and a nasty review, I happened to glance at the DIRECTIONS, and realized the valve was to be disassembled BEFORE attaching the extender, and that the black plastic piece in the packaging was a wrench intended to accomplish this very purpose, and not, as I initially perceived, a roach clip misplaced by a Continental or Amazon employee. This is a great product that works wonderfully, even if the wrench looks like a piece of drug paraphernalia.

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.

This product is just as described. Nothing to lose here. It will help you with most wheels.

Works well, requires a removable valve core

Does work at all.

Works very well for my FLO wheels. Great for Deep dish wheels. Durability so far works very flawlessly. Put close to 1000 miles on them with no air leak. I recommend using Teflon tape to make a greater seal where it screws on. Recommended

Received defective product

As close to perfect as Ive ever seen or dealt with.

Once I understood how to use the included wrench to remove the valve core and screw into these extenders they worked like a charm. I have used two other brands and types and these by far work the best.

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.
