General Information
Updated version of the original XT rear derailleur. Differences are mostly cosmetic. It came out in 1985 (I have a 1st style stamped 84 and a 2nd version stamped 85)
Most noticeable difference is the Centeron mechanism delete (used in the 1st gen XT and 1st gen Deore for overshift management).
Different pulley cage plate design (built in mud guard for the lower pulley instead of the plastic guard that mounts with the pulley, area protruding above the upper pulley is shorter)
Different inner parallelogram plate (slightly con-caved)
2 parallelogram springs instead of 1
Wider spacing on the limit screws
Removal of stamped lettering on the pivot bolts and SHIMANO on the upper knuckle
Pulley cage pivot bolt is now recessed into the lower knuckle
Pulley cage pivot pin is longer and thus tends to bend
Barrel adjuster is now fixed and does not pivot
1 ring around the lower knuckle instead of 2
Main body greatly resembles the 600 RD-6207
No notable weight difference
