Strengths:    Reliability for the price

Weaknesses:    none

Bottom Line:   
Came stock on my Hardrock. Rode it hard for 1500 miles and--while it's not the smoothest shifting derailleur I've used--it was 100% reliable. I kept figuring I'd run it till it broke and replace it with a Shimano something or other, but the doggone thing never even came out of adjustment, much less broke!!!

Strengths:    it looks good, shifts good and hasnt given me any bother in 6 months of raking the sh*t out of it. cheap.

Weaknesses:    a bit floppy, the chain hasnt got much tension, gathers mud easily and gets squeaky after that. (washing it thouroughly stops that)

Bottom Line:   
i have it on my freeride bike and rake the balls of it and its running absolutely excellent! im very suprised at this because it has lasted longer than my shimano deore's that i had. id get it coz its cheap and has turned out to be very durable.

Strengths:    smooth quick shifts

Weaknesses:    adjustment screw threads will strip out, they use a plastic insert for the threads, i removed mine and taped the hole using a 1/4x20 tap and use a bolt for the adjusting screw.

Bottom Line:   
i would buy it for cross country riding, if you do any jumps upgrade.

Strengths:    strong & quiet

Weaknesses:    probably not too great for serious shifting

Bottom Line:   
Bought this derailuer knowing I wasn't going to "shred" trails the way I used to, but wanted the SRAM quality... so far, it's been worth it. Shifts nice & quiet without any issues on the flat, up & down hills, over decently technical terrain and even chewed up a finger-sized stick and spat it out without so much as a hiccup.
Def worth the price if you're looking for a good, strong, reliable derailuer and you're not planning on racing or doing double diamond track on a regular basis. 5 flamin' turdies from me!!

Strengths:    Looks good, shifts okay.

Weaknesses:    No barrell adjuster on the derailleur itself, weak spring, goes out of adjustment fast.

Bottom Line:   
This is a good entry level derailleur, that will show its user proper maintanence because it requires it more than others.

It does do its job, and its not very expensive.

Strengths:    works as good as x5, x7
the x4 and x5 are stronger than the x7 due to the all steel "gear cage" thing, but not really that significant as far as performance. all have aluminum knucles that break easily


Weaknesses:    any aluminum part breakes easily

Bottom Line:   
The differances between the x4, x5, and x7 are nothing to brag about. The x4 works great when properly adusted and I could not tell the difference between any of them. They all break at any aluminum part, from sticks in my case, and none of them have replacable parts, except for bearing/gears which don't really break. The part that will break on these is the aluminum knucle that bolts onto the replacable derailer hanger. The differance between the x4 and the x5 is that the x4 has one plastic bearing and one metal, while the x5 and x7 have two metal bearings and the x5 and x7 have an extra part for chain/cog height adjustment, all of them seem to have a very subtle design change. I give it a 4 beacuse it broke, the third I've brook this season so I like'em cheap but I would like sram to come up with a design that doesn't catch sticks as well as these(x4, x5, x7, probobly x9 and x10 since the designs are near identical, all have the aluminum knucle)

How to adjust X4 rear derailleur

A friend of mine has a new bike that has X4 shifting on it. Any tips on adjusting the X.4? I'm still pretty new to adjusting derailleurs, and I'm a little bit stumped on where to start with the X.4 since it doesn't have barrel adjusters on the derailleur itself. I suppose most of the adjustment is ... Read More »

X7 rear der over x4?

My bike came stock with a X4 rear der, ive found an X7 locally for $35. Can I run the X7 rear on my bike with a 3x8 drivetrain? Im eventually going to convert it to 2x9 but money at the moment doesnt allow it. SRAM advertises the X7 rear as a 9 speed der but ive also read that the rear der is in a s ... Read More »

Sram X4 Rear Derailleur Compatabiliy

The front derailleur is a Shimano M191 and I'd like to get something that works a little better, and I suppose I should go with a Sr ... Read More »

X4 Rear Derailleur play at the hanger pivot

How far up the line of derailleurs do have to go for a decent RD that will stay in line on the cogs without lateral play at the hanger? Do any have bearings there? I think mine is missing a thin o-ring on the pivot bolt, is there supposed to be one? About to order an X9 but the X7 is <$40. Help ... Read More »
