World’s flimsiest disc brake mount?
The GT’s rear brake mount is just two posts brazed onto the NDS seatstay and dropout. When I was tweaking the rear brake today (brazing a cable stop onto the seatstay) I grabbed a fistful of cable and drew it taut so I could realign the brake and saw it shimmy back and forth. Ah well, I was planning on cutting a couple of pieces of webbing out of sheetstock so I could tie both mounts together for paranoia’s sake, so it’s not as if that’s going to be any work I wasn’t already planning on doing.

Possibly! I’m not sure if it would be necessary, given the length of the rear triangle (if I lock the brakes the rear wheel just slides) but it’s pretty trivial to glue in a piece of 5/16ths tubing while I’ve got the torch out.
Yeah, that’s a big lever. What do you think - 4 to 1? 5 to 1, maybe? I think some Surly’s basically have a tube that connects to the chainstay from the top stud of the brake mount.

Maybe a gusset between the seatstay and the chainstay might be a good idea, too?
