looks like you need one to run a 140mm rotor as well
That's for a front brake. Flat mount front needs an adaptor - you have it one way up for 160 mm rotors and flip it for 140 mm.
Rear does bolt directly to the frame if you're using 140 mm rotors. You need an adaptor to use 160 mm rotors at the back.

Sorry to ask yet another disc brake mounting question but can anyone exlpain what the trp spyre adapters are for? I assumed it was so you could run a 160mm rotor but it looks like you need one to run a 140mm rotor as well? I'm confused, I thought that flat mount was just mounted directly to your frame?
