Title: The Disc Adapters r Dun - About those calipers...

These are the finished products. Wish I had some good advice to give on an easy way to gitter dun. It just wasn't that simple.

I'm pretty sure the front adapter design would work as well on Carbon forks. (An epoxy buildup on the leg with the aluminum plate cast into it.)

The front:

Wahoo!  Will

Nice work Will,nice to also put a face to a name :),
shame about the B4's had mine a couple of years and they've been nothing but outstanding and reliable (though the Hope mono mini's are tempting),sure they'll be fine once you've sorted them.

Very nice! Looks like a factory job.

I like the white paint.

Both disc adapters started out with mechanical attachments using the skewers to hold them in place.

On the front I had to grind down the "lawyer bumps" for a flush fit on the outside of the dropout. Once it was mechanically fixed, I sanded the paint off the fork leg around the tab location. Then I made a mold (out of aluminum tape) on the fork leg that surrounded the aluminum plate. I filled the mold with JB Weld making sure the epoxy penetrated through several small holes in the plate. After everything proved out, I cut off the plate above the dropout for a cleaner and lighter job.
I'm really confident in the build because I actually tested the brakes before they were epoxied in place.

On the back I used almost the exact same method. A nice bonus was an extra threaded hole near the dropout that I used to secure the plate in place.

The good new is nothing but paint and "lawyer bumps" were ever ground or cut away. So... structurally it should all be ok.

Kiwi,

The rear shock is just the old ODS damper with 350# die spring. Very heavy, but also VERY cheap. Don't think I'll invest in anything else until an SPV air shock becomes available for a decent price.
