I have a little project, to put discs on my bike with as little cost as possible.
Now, part of this plan is to use cheapass cable discs (either shimano or tektro), and run 8" rotor. Obviously these are designed for 6", so I need to make an adapter.
Here is where I need help, I have the idea, just need opinions... so, the plan is this (excuse my crappy art skills)
Get some alu plate, the same width as the disc tab. Cut it into 3 pieces, parts a, b and c.
Parts a and b are the same shape, they will be mounted either side of the tabs, and have bolts running through to clamp them together (I do realise rotor clearance will be an issue). Part c runs in the middle of a and b, and will be bolted in 4 places, it'll have holes for the brake caliper to mount.
In theory, this should give the same spacing as the original disc tabs, and providing I support part c enough it should have minimal flex.
Is this idea viable? Has anyone else done it?
I guess I could run the shimano brakes with hayes adapters, but that'll increase my costs by 50%, something which I am very reluctant to do.
The costs have been added up, and if this adapter idea is possible, then I'll go ahead with it, but if it won't work, I'll give up the idea of discs for a while (I'm trying to keep a very tight budget).
