are b-screws always near the rear of the derailleur..
i just picked up a used shimano RC long cage derailleur that i'm going to throw on a beater bike. From my experience from other derailleurs, is the b-screw supposed or always supposed to be near the back of the derailleur (8 o'clock position in relation to the mounting bolt). This derailleur has it oriented near the front at say a 2 o'clock position. Are different derailleurs made for different types of hangers? Or has the spring in this one slipped and shifted?
Campy has one as a lead screw in the lower pivot.
