looks like a bottom pull to me
yes it does like a bottom pull to me. you could get an adapter if there is a screw hole in the shell to run the cable underneath. if not you would need drill and tap some threads.
you could also try to fund some onl shimano or suntour screw on cable stops to run on the down tube. if you have oversized tubing you probably wont find anything compatible.
other than that **** can the der and hit a used shop and pick up a top pull if the frame is set to bring the cable down from above
