In the process of cleaning up this weird thing. 2001 schwinn panther SS. Aluminum 7005 frameset with Mtb geo. Single speed drop outs but has all of the cable stops/ hanger to run a front and rear derailleur. Has deore brakes and a threaded deore lx headset on it. Only annoying things are the 1in threaded fork and the use of a u brake in the rear which limits tire size to a roughly a 2.2 so I have to go buy one with more clearance for 2.3-2.4. Going to go full on 3x9 with shimano xt derailleurs/wheels and race face cranks. I have all of the parts but I always manage to switch things up.
