Looking for fitting flat mount to post mount adapter
Alright so I’m getting a bit of a headache trying to figure out if what adapter I could use. I’m building up a kona sutra ltd frame, which has a flat mount frame and fork. I’m going to use it pretty heavily loaded since I’ll be cycling from Japan to Europe. I still have some Trp spyres laying around that I want to use, but they are post mount. I’d prefer to run a 203mm front rotor and 180mm in the back, and although there are some flat to post mount adapters I’m not sure which ones I can use.
Also not sure if it’s even smart to go up to 203mm because of the added force on the fork, so I’d be okay with 180mm in the front too. I think the frame is designed around 180mm rotors if that helps.
Would the ones by Trp I added in the pictures work, since the bike is already based around the 180mm?
Edit: Alright so 203 in the front is not going to happen, I’ll get a 180.
