I just bought a new "still in the box" Shimano C series (C201) front and rear deraileur set off of ebay for $17.

I think they are bottom of the rung equipment for Shimano, Heck I don't even know if they will even fit on my old Schwinn Crisscross?

I never thought my bid would win, I was the lone bidder on 'em.

Anybody know anything about them?
