Shifty is right about the SR CA brake thing cause i have used both with the brackets. but CA is better as far as fitting smallish rims. We have never had a problem getting hold of kev rowley. If your still hitting a brick wall in a week or so get in touch with me i can supply you a trace of a bracket you only need one as they can go on either side we will also supply a vernier caliper measurement of the thickness if you like then you can get them converted to cad drawings and laser cut.
