Hey you are right, I didnt realise there wouldnt be a braking surface.
The sun actually looks pretty good. Im having problems deciding between 32rear and 28front or 28 F&R.
If I got with 2x28 then both Sun rims would be great. I am not bothered about the colour mismatch.
If you have any hubs to go with them it would be superb.
I may take the used cxp off you too, just in case.
