Whats up with this XTR rear derailleur without a barrel adjuster
Was making my weekly rounds at the dump and came across this XTR derailleur. Diamond in the rough :cool:

No barrel adjuster though. What gives? Did this model just not have any? Did Shimano assume you had one on your shifter? Kind of a bold assumption given that most of Shimano's MTB brifters do NOT have barrel adjusters for the rear derailleur. I do think their pod shifters do though and the XTR shifter pod does.
One of the jockey wheels teeth are pretty worn too. Any source for a single replacement jockey wheel?

Perhaps the original owner salvaged the adjuster before tossing the rest. I'll often salvage useable parts from otherwise worn out components.
I assume the derailleur was in the trash for a reason.

Soil Sampler has it right, it's a Rapid Rise. The way the cable loops in doesn't lend itself well to having an adjuster, I have a barrel type mounted in line (Cross-Check with barcons).

The previous owner probably wore the barrel adjuster out trying to keep the derailleur quiet. 
Seriously, that particular version of XTR Rapid Rise is one of the most troublesome RD's ever. My brother in law had one, it was a constant PITA. Later, when Shimano re-introduced Rapid Rise ('02, '03?), I read an interview where one of the top Shimano guys admitted that with the earlier version of Rapid Rise, about the best you could hope for was to keep it in adjustment for the duration of a race-

Interesting. Don't know my vintage, it was NOS in my LBS's pile of acquired parts, but it has performed very well, in fact I don't think I've had to adjust it since the initial install ( thankfully, since the barrel adjuster on the downtube boss is a ***** to turn ).

The only problem with this derailleur is the worn jockey wheel and that can't be more than a few bucks
