RockShox BAR Air Valve Assembly

I had a malfunction with the rear DNM shock on my ebike and the air valve was broken. I contacted DNM to see if I could order the part from them and they were going to charge $10 for the part and $55 for the shipping because it was coming from Thailand. So after trying the local bike shops with no luck, I continued my search and found this one. I took a chance that it would have the right threads and was happy to see on the package when it arrived that it was made in Thailand, so there was hope. It ended up being the right size and the right threads so it screwed into the shock but the center hex size was larger and I had to modify it a little so it would thread in all the way to seal. I was able to put my shock back into operation until the bike manufacturer sent me the replacement shock from China.

Restoring my 1994 vintage Specialized Rockhopper FS.I used 2 of these to replace the failed stock butyl valves (type of valve used for inflating a ball) on my front Futureshocks. Those valves had hardened and would not hold pressure. They are mounted in the top inner plug of the shock.I drilled out the hole for the butyl valve, tapped it with a M7 x .75 tap, a little teflon tape on the threads, recharged the shocks with fresh oil and 35psi of air pressure and now my ancient shocks are holding pressure and working again! Thankfully, the old O-rings in the shocks are still good.I chose this Schraider since it had the lowest height of any Schraider valve I could find which allowed me to still use the top cap of the shock to keep debris out of the upper part of the shock tube. It still protrudes above the top of the shock tube but only by 1/8" so the cap still fits snug, just not all the way down.These shocks were never that great, even when new, but I wanted to restore this bike (that I haven't ridden in 20+ years, because the shocks went flat) to bone stock condition. These valves have gotten me over the biggest hurdle!

Well made it doesnt clame to fit fox shock but looks about right so I tried it does not fit fox shock.

I bought these after reading how another reviewer had used them to replace the leaking ball needle valves on their mountain bike suspension fork. They work great and are much easier to inflate accurately.The hardest part was drilling and tapping the stanchion tube caps to accept the air valves. One of mine is a tiny bit crooked but, the rubber o-ring above the threads makes sure the fit is air tight. I used blue threadlocker to keep it tight without using too much torque on the threads.

Buen producto, se recibio a tiempo muy satisfecho

Leider habe ich an meinem RockShox Bar Dämpfer das Ventil zerstört. Das Ersatzventil war meine Rettung.Einfach altes Ventil rausschrauben, dieses rein schrauben und schon funktioniert alles wie gewohnt. Ich bin echt froh, weil ich keinen teuren Dämpfer kaufen wollte. Vielen herzlichen Dank! Thank you!

I broke the valve attachment from the 2021 Rockshox Super Deluxe Ultimate rear shock due to my negligence. I deflated the shock and compress it with the Air pump attached and it hit the linkage and broke of the valve screw cap attachment. Unfortunately it's together with the shock body. So I have to modified it. I drill a hole, file it flat than screw tap it with M7x0.75. install it with a thread sealant and to my surprise it work with leakage. Awesome.
