Hi! I have a wee problem with brake adaptor.
On front I have TRP slate t4 brake and Fox rhythm 34 fork.
Ran it with 180mm slx disc and Shimano +20mm adaptor. Worked fine.
Now wanted a little more power so switched to 203mm XT ice tech disc and shimano 203mm sm-ma-f203 p/p adaptor.
And it doesn't fit. Caliper hits the disc at it's lower point. Putting 1.5mm washer under the lower mounting point solves it.
Tektro sells it's own adapter, but it looks basically the same, only bit more curvy.
So anyone have info on this?
Are the adaptors really different?
Hoping to get knowledge, not something like "In my opinion" or "I think that..."
Thanks for advance.

Post pictures, it's easier to diagnose.
Does the frame and fork have the same size Post mount? What I mean is, without adapters does the frame and fork accept the same rotor size?

I think some newer forks are designed for a minimum of 180mm rotors so I think there are two different 203 adapters

I reread it and I see what you're saying.

When I first read it and you were talking about the curvy part of the TRP/Tektro adapter, I was thinking the flat section of the Shimano adapter wouldn't let you attach the TRP caliper without extra spacing.
