PhilDAS-
I'm just learning about disk brakes so sorry if I'm getting it wrong, but the Kinesis 'recommends' 140 at the back but it appears in the case of my frame, it's the only option.
Juin Tech say only to use 160 and the rear calliper lines up to a 160 without any adaptors.
The frame comes with flat to post mount adaptors but they are for 160 which is stupid as the frame won't take them!

Ok, so I just pick the coolest looking rotor, I can do that.
But I have an issue...
My frame is a kinesis 4S and now I'm way to far into the build, I find it can't quite fit a 160 rotor on the back. It just scrapes the lump caused by the weld where the chain stay meets the drop out.
But... on forum advice, I bought Juin Tech F1 brakes that you are only meant to use with 160 rotors.
Is it possible to just use Juin Techs with a 140 rotor? My logic says that they are designed for a 160 so the pads won't line up with a smaller rotor and there is no way to step them down. That then leads to filing down the frame slightly, or using HY/RD which is a little annoying and more expensive.
Thoughts?
