OT but yeah have searched and bladder is a pretty common term. North had that T valve business but I was thinking of something else. Was personally never affected. From searching it looks like multiple companies have had bladder QC issues. generally a pain in the A$$ for both retailer and consumer.
This is from some post in November on problems with 2010 chicken loops so not as old as 2008
the bladder issue affected loads of brands. And some major brands aswell..
The batch of bladders LOADS of them, where made wrong and thats when they teared even with just looking at them. But after that it should be alright. Its something thats totally out of the hands of the companys. It sucks drasticly i had to replace all my bladders aswell but i got em all send over really fast.
The factory solved the problem by now and the new bladders are good as far as i can tell.
Thought lines were generally well sorted by now, but if there is a cheaper option companies might go for it only to have it backfire. I know at least three companies other than Cab have similar looking lines. Thats just what I've seen, there are probably more.
