Black Mountain Cycles posted this today on a Yeti in for work. Pretty clever way to run a bottom-pull derailleur on a frame with braze-on routing for top-pull. (Well, if you don't count the necessary braze-on for the chainstay cable bolt.)
Solves the common problem of locating a cable barrel adjuster for the FD as well. Is that an older side-pull road caliper cable stop set-up? Cool beans.
Rocky Mountain actually solved this problem on some of their older bikes by mounting a pulley on the back of the seat tube near the bottom bracket. I'll try to get some photos posted here of that set-up since I have just such a frame in the closet.
I've been trying to set up the Rocky Mountain with an old Ritchey 2x9 42/29t chainring set up. My top-pull Suntour XC Microdrive triple derailleur has been balking at having to try to shift this, with good reason. Pretty hard to find a top-pull double front derailleur from this time period. Looks like some McGuyvering in this direction might be warranted. I'll keep you posted.
