Lightweight flat mount adapters on Aliexpress

[hubba]

Has anyone used those lightweight flatmount adapters on Aliexpress? They would be a cheap way to drop some weight as they are half or less the weight of original Shimano ones.

I mean adapters like these, there are cheaper ones too but I'm not sure which I can trust.

I have original mounts from Chaser for around 4 months and quite happy with them https://www.aliexpress.com/item/1005006968796582.html
Wouldn't trust extremely lightweight cheap part in general - it could be made from lower grade alloy and bolts could be crap too. These look pretty much the same, they also have the same sticker pack in the reviews, although no mention of the brand. I have a suspicion it could be counterfeit or stolen from the factory.

Might as well go titanium!

I am currently using this one. Imho any of these avaiable are alright. It’s just a piece of aluminium, so I don’t think there is anything to worry about. Chaser is a more known (and more expensive) brand, but both this one I shared and the Chaser one are made out of a CNC’d 7075 alu (their claim lol), so it’s basically the same.

Rrskit has titanium ones at half the price.
