I’m building a flat bar gravel bike and I was going to use an old pair of xt brakes from another bike. Unfortunately the xt brakes are made to thread into the frame, and my gravel bike is made to thread into the brakes. What adaptor do I need to make this work?

Flat Mount to post mount adaptors front and rear.
You need a [Flat mount to post mount adapter](https://www.merlincycles.com/trp-flat-mount-to-post-disc-brake-adaptor-89957.html?utm_campaign=googlebase-CA&utm_source=googlebase&utm_medium=shopping&utm_term=MTB+Disc+Brake+Rotors+%26+Spares&ucpo=27021&gQT=1)
If ur plan is going flatbar with deore xt and need xt brakes note there are xt flat mount u can get
I just went through this with a new gravel frame and mtb brakes. A few companies make adapters but they look wonky and seem like a compromise. I just paid the $80 each for the correct calipers. They’re easy to swap and don’t cost dramatically more than the adapters.
I feel like brakes are never a bike part you should half ass.
You’ll need a flat mount to post mount adapter.
Here’s the brake mount adapter model breakdown from Shimano: [https://productinfo.shimano.com/en/compatibility/C-193](https://productinfo.shimano.com/en/compatibility/C-193)
So, you would need either SM-MA-R140P/D or SM-MA-R160P/D.
WORD OF WARNING THOUGH:
I had a pair of SLX brakes that I tried to do this with, but I ran into issues with the clearance of the caliper and seat stays on the rear triangle.
I ended up having to buy a flat mount brake and picked up an SLX flat mount to match the front SLX paired w/some GRX levers.
is this a niner rlt?
