Disc Brake Retrofits

Slotted Dropouts

Kirk Pacenti sells some nice tabs that can be welded to old single speed frames to get them up to speed with disc brakes. I wish that the lower tab was longer. It was very difficult to preserve the usefulness of the slots in this application. I lost 1/3 of the slot range.

Don't forget to add a little support to the seatstay when mounting the tab directly to it.
