What disc brake mount adapters do you guys use?

[Sam Song]

I am looking at upsizing brake rotors from 7 to 8 inch on my Hex. 

After having extensive experience snapping brake adapters on my previous bike, I want to get an adapter that will last. 

I can get Hope adapters pretty cheaply where I live. Do Hope adapters have a good reputation? They still look pretty skinny to me.

Hope are about the strongest I've come across. There might be chunkier, but the Hopes are chunky enough and well thought out enough that they're fine.
They're CNCed from billet. A lot of the others are cast, which means the material is less dense and porous. More dense, more consistent, and not having sharp corners right where all the stress is going through like some others make them pretty damned good.

If it settles your mind at all, I broke a Shimano one, a SRAM one and the one that comes specifically with Avid brakes. Then got a Hope and haven't broken one in 18 months. About a year of that was on the rear of a 26" too.

Check the Hayes one if you're not made of money.

Frame is post mount? Then getting one of those in line adapters might be strongest. IS to PM I've had good luck with Magura. Broke the Hex in two, not the adapter 😁

With Magura it's a bit complicated though. There's at least that one 180mm IS/PM design that can't take the stress, it's too thin at certain point. Not sure what it was exactly, but I cracked one pretty quick and some others have as well.
