Strengths:    low profile , precise clean shifting , ease of fitting and setting up

Weaknesses:    none I can find

Bottom Line:   
I got this to replace my 14 year old lx r.d .that I broke , well my old R.D. was good but this is so much better , all I had to do was put it on the bike connect the cable and tighten it a bit and it worked perfectly, it didn't need any adjustment of any of the screws and the gear shifting is so quick and precise I just wish i'd got one sooner , you cant even see it if you look down because its hidden under the chainstay and the inline cable routing is fantastic too ( no big loop to snag up ) ,
I was a bit miffed when I saw it had no rear tension adjustment but you realy don't need it tbh,
this is pure quality and would recommend it to anyone, i'm a very happy chappy indeed

Strengths:    Looks and works great.

Weaknesses:    Had to learn to adjust from the shifter.

Bottom Line:   
After realizing my cassette was bad adjusting it was simple. I learned that if your shifting is slightly off and pressing the thumb shifter lever in a bit resolves it, screw the barrel adjuster out. If pressing the thumb shifter lever makes it worse, adjust in... Set your high and lows stop screws just a hair to the outside of the outside rings like 1/16 - 1/8" and its go time!

Strengths:    sturdy, decisive positive action, looks good, easy to fit and adjust.

Weaknesses:    none so far

Bottom Line:   
i have replaced shimano tourney with SLX M662 SGS long cage shadow and has brought my bike up to another level. my mountain bike is an entry level example although has a very good frame, rims and front suspension forks. the shimano tourney derailleur (and the peddles which i have also replaced) really brought the overall rating of this machine down and the M662 shadow has turned the bike into a good quality piece of kit. i highly recommend the M662 to anybody who has a entry level derailleur and feels they would like to upgrade without spending lots of money. very nice positive action, fitted them myself and found adjustment very straight forward. very happy with results

Strengths:    None

Weaknesses:    Poor design, too short cable housing in rear, cable set screw in odd place. What were they thinking???

Bottom Line:   
What a horrible little derailleur. The worst I have ever encountered in over 50 years of cycling. They should replace every one for free.

Strengths:    Low profile, accurate shifting, nice looking

Weaknesses:    none so far

Bottom Line:   
A very nice surprise!, I bougth this bike to my daughter and after riding several days on it I don't find a performance difference with my other full XT bike, it works very well in both up and downshifts, the low profile is great and the cable route reduces drag, making crisp accurate shifs every time, even with the Alivio shifters on this 8 speed bike, I can tell the shadow technology really works!!

If you want XT performance without emptying your wallet SLX is the way to go, much better than LX

I'm thinking to replace my traditional XT Rear derailleur to shadow

Date Reviewed: January 25, 2010

Strengths:    Accurate and quick shifting, durable, low profile, more direct cable entry

Weaknesses:    No barrel adjuster (no big deal)

Bottom Line:   
I've found it to be a durable, reliable derailleur for a decent price that gives you appreciably increased clearance. I'd buy another one any day, it has been a good performer and hasn't caused any trouble at all. Cable access on this derailleur is a bit better than traditional designs as well, there's less of a loop sticking off your bike.

The only downside is that there's no cable adjustment directly on the derailleur, which is more of a minor inconvenience than anything.

Bottom Line:   
the spring in this thing busted while i was 7 miles from my car. not the shifting tension spring, but the other internal one. i ride my bike hard, but this thing failed in a very easy low stress spot on the trail. no idea why it broke. i dont like it. i have a sram set up on my XC bike (x7 shifters and x9 derailleur) that things been eating what i throw at it for more than 2 years and it still works. whats goin on shimano...

Strengths:    Smooth gear change, hides away nicely to avoid getting damaged, strong (can take a hit), good appearence and good price.

Weaknesses:    Sometimes 'sticks' and takes a few seconds to shift, difficult to clean.

Bottom Line:   
Altogether good rear derailleur, Damage resistant and nice gear change. Good price, and only minor problems. Good for entry level-ish to medium Cross Country, but if not you will still like it.

Strengths:    No chain slap at all. Low profile prevents snags. Smooth and precise shifting.

Weaknesses:    None so far.

Bottom Line:   
I wanted to get the XT version but my bike is near the end of its lifecycle so opted for the cheaper SLX. About $ 60 less. Functionally speaking it has the same general technology. I haven't taken it out on a really gruelling ride yet but so far this is a vast improvement over my old XT derailleur(s) I have had to replace 3 of them due to the tendency for them to break or get torn off. The low profile will probably reduce this and seems to fit very well with the Specialized set up. The chain slap is completely gone and the shifting is 2X smoother than the previous set up. Only 4 chilis because I don't know how long it will last. Hopefully until I decide to get a new bike.
