The next bike down from the Stuff, the Scrap, has the gussetted chainstays, but lacks the (lame) disc brakes. If you're like me and were going to replace the fork and the brakes anyway, you might consider going with the Scrap instead.
The fork is one step down from the Stuff to the Scrap also. Its not a very big step. Both forks are lame, one is just a little less sticky courtesy some teflon covered stanchions.
