Quoted message said:Apart from price that is....
Just what are the reasons to justify the price differences? What do
XT/XTR ACTUALLY offer over LX?Is it better function, longer life, etc etc???
thanks
There are two of each: weight goes down - price goes up, and:.
The new M760 Deore XT group adopts Shimano's "low normal" return spring
design, yielding far smoother shifts to larger cogs under pedaling pressure.
No more slipping under load! With the low normal system shifts to the bigger
cogs are just as smooth and effortless as shifts to smaller cogs are under a
traditional derailleur system.
Shimano didn't miss the details, either - the derailleur now features a
rubber bumper on the body that reduces noise and adds durability, and a wide
link design that increases rigidity and service life.
Weight: Med cage: 232 g
Long cage: 362g
Compatibility: 9 speed drivetrains
Feature: Low normal return spring
M750 XT
Weight: 245 grams (long cage)
Compatibility: Mega-9, 34 tooth maximum rear cog capability
Feature: 11-tooth pulleys reduce wear by alternating tooth contact, sealed
bearing pulleys, cold forged alloy construction
Shimano's new M960 rear derailleur comes in both a medium cage (GS) or long
cage (SGS) style, accomodating both narrow and wide range drivetrains. Both
are compatible with Shimano's new XTR dual control levers, providing highly
accurate and efficient shifting that reacts precisely to the movement of the
shift lever.
The M960 incorporates a high rigidity outer link, which embraces the pulley
body to increase pivot joint rigidity.
Mega-9 compatibility ensures smooth, positive, light action shifting on 9
speed drivetrains. Each pulley uses an oversize, 11 tooth design which
offers smooth, low friction rotation, thanks to their sealed bearings.
Features Shimano's "low normal" return spring, enhancing shifting action to
larger cogs under load.
Weight: 198 grams (GS)
Compatibility: Mega-9 (9 speed drivetrain) compatible
Feature: Flourine coated bushings means less shifting effort
M952 XTR
Weight: 207 grams (Medium cage)
Compatibility: Mega-9, 34 tooth maximum rear cog capability
Feature: 11-tooth pulleys reduce wear by alternating tooth contact, sealed
bearing pulleys, cold forged alloy construction

The rest I've just wasted.
