2023-09-09 - Replacing an 02 Cabrinha Mantis wing inflation valve with an Airtime valve.

It appears that Cabrinha has a problem with leaking inflation valves on the Mantis 02 and maybe 03 wings due to faulty plastic with the portion of the valve that is glued to the bladder. In our case, most of our 02 wings, after about 10 months of heavy use, are all showing leaks when you slightly wiggle the inflation valve. This opens up the forming crack at the base of the valve that is attached to the bladder and releases air.
This video runs through the process of replacing the valve with an Airtime replacement along with how to identify the problem. Make sure you follow all of the steps for a successful repair!

Great video. I could not find an Airlock 2 Valve Replacement video from Cabrinha, so your's was very necessary.

Great video but what a hassle. Brand new mantis with that problem on first inflation.

[@marcjorrens9161]

Total hassle! I can do it in 20 minutes now as I have done more than 12. Probably 6 of ours and 6 from friends. Yikes! The Mantis V2 and V3's have the problem. Not all of them but I would say 30% or so. The V3's are a little harder to do as you need to press pretty hard on the strut inflation valve (start with a corner) to push them through to inside of the bladder so you can have enough slack to pull the inflation valve out.

I have this exact problem - on my 4.0 v2, with loads of bubbles coming up around the valve and through the Velcro - so I’m delighted to find this video! Thanks. For the bladder patch - is it an airlock V2 kit that I need? Many thanks!

Glad the video can help! Here is the patch: www.airtimekite.com/cabrinha-airlock-ii-valve-2nd-gen.html

Thankyou! About to do this to my 2meter which blew out at this joint on a 35kn + day. I went out with a bigger wing anyways and got destroyed + walk of shame😢

Go big or go home!

[@antonioeduardo249]

Hi, very good. I saw you did a repair on the handle too. Mine broke too. Do you have a video of your repair?

[@lhcoolbreeze5753]

I just purchased a v2 Mantis in 3.5². I got to use it once last week. It leaks already. I had a close out Duotone do the same after a few inflations. The valve plastic obviously goes bad sitting on the shelf.

[@marcjorrens9161]

Oh boy. Lame! I know Cabrinha had a bad batch go through with the V2s and now the V3s too. We have had to fix two V3s already.

[@lhcoolbreeze5753]

@@marcjorrens9161 At least it is repairable at home. Thanks for filming the process! It will be prove invaluable when my new valve arrives.

Thanks a lot for the video. I'm about to do the replacement on my Mantis 5.0. I've only ever had Mantis wings and I was planning to buy the newer Mantis V3 but now I'm wondering if I should get a different brand that doesn't have leaky valve issues. I am considering buying the Slingshot V3 HH instead. Do you know if the slingshot V3 uses a similar valve and if it also has valve issues? Do you still only ride Mantis or have you found another wing you like? Thanks

[@marcjorrens9161]

Excellent question. There are problems for sure with the Mantis V3 wings. Probably 30% have this problem. I believe they have finally resolved the issue with the V4 wings. I really like how the Mantis flies so I would not switch brands. I would think the Slingshot does NOT have this problem unless the bladders are made in the same factory which I guess is a possibility.

[@jamalschott5547]

That light is awesome - where did you get it?

[@marcjorrens9161]

It is a Ryobi 18V work light (battery)

[@johnseely5532]

How is the Airtime valve holding up? I just got a brand new Dakine cyclone V2 made in the same factory and within 10 minutes the main valve is leaking.

[@marcjorrens9161]

Rock solid. Some wings are going on 6+ months. Looks like they finally rectified the problem with the Cabrinha V4s but Cabrinha V2's and V3's both have the problem. From what I hear, 30% of the wings manufactured have this problem.

@@marcjorrens9161 Great video! Will this airlock replacement valve work in a V3 Vision? Thanks!

@@michaelsmith8231 Almost sure it will.
