I have the Magene Teo cranks, but disappointed by the super cheap plastic preload collar, which can jump threads.  Is there an alloy aftermarket replacement? The SRAM dub aftermarket preload collar won't work as it's a different design, as far as I can see - 2 parts, whereas Magene is just 1 part. Or will the collar still fit? Anyone tried it?

I've never seen a Magene crank in person, so I'm not sure how the preload setup is. But if it's the same as the ones used on carbon cranks, a replacement should be easy to find. Worst-case scenario, if you can't find anything on AliExpress, try reaching out to a dealer or the manufacturer to see if they can sell you the spare part.

I've found for DUB...

Can confirm the Muc Off alloy preload collar without the inner rings works, as inside diameter is correct. I tried some AliX options but these were for dub and the inside diameter for the threads was too small. I found the plastic original works better if tightened a little before setting the preload, as it stops the plastic threads skipping. It also has to be tightened well to stop it moving. But I still feel an alloy preload ring is a better option so sticking with the aftermarket solution.
