    Submitted by Captain Hypocrisy a Cross Country Rider from Bozeman, MT
    Date Reviewed: August 30, 2008
    Favorite Trail:Hard climbs, gnarly descents
    Duration Product Used:2 Years
    Price Paid: $65.00
    Strengths:Durable, reliable, consistent shifting.
    Weaknesses:Not very flashy, but that's okay.
    Similar Products Used:Deore LX, XT.
    Bike Setup:2005 SC Heckler, built for heavy all-mountain riding.
    Bottom Line:Mine is a 2005 model, and I've been thrashing it since I got it. I've hit it on rocks, concrete walls, and caught it in branches. I do some drops and jumps when the opportunity arises, but mostly I just climb up and then go downhill as fast as I can. I've replaced the cable about once per season, and it has performed flawlessly. Set up is easy, and once it's set up and the new cable has finished stretching, I almost never have to adjust it again. The SRAM trigger shifters are my favorite and I'm totally sold on the 1:1 ratio business. Granted, I never tried Shimano's top of the line derailleur and shifters, but I had nothing but problems with their other products, and I don't think I should have to buy the top of the line product to get consistency. I'll keep riding this thing until it's dead.

    Buy this derailleur if you like riding more than adjusting, and if you're interested in rock-solid reliability over bling-factor.

    Bike Setup:Redline D660 29r. (nine speed)
    Bottom Line:the x.9 came on my bike and on my second ride the thing snapped on me. i've never experienced a bent hanger or derailleur in my 18 years of mt. biking. since then i've bent the new one 3 times. i will admit i'm hard on bikes, but like i said, i've never had this problem until now. i thought i was going crazy until I read the other reivews; it's comforting to know it's the product...

    Duration Product Used:3 months
    Price Paid: $65.00
    Purchased At:JensonUSA
    Strengths:Shifts quicker than any other derailleur I have ever used!
    Extremely easy to tune due to SRAM's 1:1 actuation ratio technology. Very strong in my experience; many other reviewers complain of how easy it is to break but I have hit this thing against some pretty large rocks multiple times and totally smashed it once and all that happened was a bent derailleur hanger and some scratches on the derailleur, it still works like NEW! This is the best derailleur for your money!
    Weaknesses:I can't think of one!
    Similar Products Used:Deore and Deore XT rear derailleurs.
    Bike Setup:2005 Iron Horse Warrior Comp
    Avid Juicy Three Disc Brakes
    SRAM X.9 Rear Derailleur & Trigger Shifter
    SRAM PC-991 Chain
    E.Thirteen SRS Chain Guide System
    Bottom Line:This is the best derailleur I have ever used. It shifts very quickly and it is very strong. Many other reviewers have complained of breakage or poor performance; maybe they don't have it tuned correctly? If your derailleur is going in to your spokes you might want to look in to a new derailleur hanger before blaming the derailleur. I have really beat on this derailleur and I couldn't be more happy with my choice in this component. I have ridden in all conditions from dry to completely submerged in water and this hasn't let me down yet.

    HIGHLY RECOMMENDED!

    Favorite Trail:One that doesn't break my X.9
    Duration Product Used:6 months
    Price Paid: $99.00
    Purchased At:LBS
    Strengths:CRISP shifting, I love the 1x1 actuation. Self-cleaning is nice.
    Weaknesses:The cage itself (possibly a long-cage problem)
    Similar Products Used:Shimano Deore
    Bike Setup:Fully custom Niner Air 9.
    Bottom Line:I upgraded from a crappy Deore setup to a full X.9 setup and have since snapped two rear derailleurs (both rear) in SIX MONTHS! I should note that I am not a super hard rider, though we do ride some semi-technical stuff. I'm disappointed in the X.9 rears so far. I've been using a long-cage, but since I run a 22/32/bash setup, I'm going to go with a short-cage and see how it works out. Hopefully, I have better luck with that as I dread going back to crap-mano.

    Strengths:- Crisp shifting
    Weaknesses:- Weak
    Similar Products Used:Deore, LX, XT
    Bike Setup:2006 Norco Six One
    Bottom Line:I really tried loving this product but after going through 3 RD in one season I've got to be disapointed. I almost jumped and switched to Shimano after breaking the 2nd one last year (both time the cage bent on very small impacts, i.e. walking next to the bike and hit a rock) but the guy at the shop told me they fixed this problem on the '07 version. And they did but something else breaks (this time it's the low setup screw that bent). I'm buying a last one. Going for a short cage this time and it will hopefully be compact enough to avoid hitting it but as soon as this one fails, I'm going for an all XT setup, period. SRAM you've already spent your last chance, if it wasn't that I need to change the shifters (and that I spent too much already), I'd buy an XT right away.

    Strengths:Shifted nicely for 3 years
    Weaknesses:Self destructed without warning after 3 years
    Similar Products Used:xt, xtr, lx
    Bike Setup:Santa Cruz Superlight
    Bottom Line:I've had the same problem as some reviewers below. It worked well for 3 years, then the body of the derailleur broke where it bolts onto the frame. This resulted in some bent spokes, a mangled chain and a long walk home.
    It shifted nicely (no better or worse than above mentioned shimano) but I think it should have last longer and the collateral damage due to the sudden failure is expensive.

    I keep my drivetrain maintaned and clean and replace parts as needed to avoid this sort of problem.

    I weigh 145 and ride cross country - 2 or 3 24 hour races a year (team of 4) About 800 miles per year on this bike. I usually get good life out of equipment at the xt or X9 level. I got 10 years out of shimano xt so I was hoping for similar performance from SRAM X9. I think I will go back to the dark side and hope Shimano's new version of xt is as durably as the old stuff.

    Unless SRAM has addressed this problem with their new X9 derailluers I would not recommend this product to anyone.

    Strengths:Trouble-free operation with occasional cleaning. Shifts well. Not a horrible price. (if they would last)
    Weaknesses:Breaks easily. Shears off just under the skewer if the wind blows thw wrong way. The X-7 was equally disappointing.
    Similar Products Used:SRAM X-7 (see my X-7 review, it's about the same as this one)
    Bike Setup:06 Rush. Maverick SC32 fork. mech/discs. Nothing fancy otherwise. It will have a new derailleur soon, but not SRAM :-(
    Bottom Line:I am disappointed by the short life span of both the X-9 and 7. Morseon the 9 because of it's price and because it only lasted a few months. I have a $75 paper weight now, but it does match my X-7 paperweight.

    These things really do a number on spokes when they grenade too. Factor that into your replacement price, as you'll be getting wheels rebuilt more than you change socks with these little trouble-makers.

    Watch for shrapnel too. They don't go quietly. Bring shoes that are easier to walk home in - or bring a chain breaker so you can at least rig it so you can ride back after the imminent failure that will ensue should the derailleur brush up against a blade of grass or a soft dandelion while you're out riding.

    I will do my best to avoid buying their products from now on. Save you money on both the X-7 and the X-9. I have seen quite a few similar reviews about these things.

    Strengths:Looks good, light, fairly easy to fit.
    Weaknesses:The derailleur bolt.
    Similar Products Used:Shimano
    Bike Setup:RIP 9 AM.
    Bottom Line:Second ride with this brand new derailleur, and it broke the bolt that attaches it to the hanger...and that gave me a long walk home.

    I usually run a Rohloff Speedhub, and have been absolutely spoiled by it's reliability and no - fuss shifting.

    I am very disappointed in the SRAM X9 derailleur. I never hit anything, I just changed gears, and *SNAP* ... it was busted. It snapped off and slammed itself into the cassette.

    The bolt that holds the derailleur to the hanger is a hollow alloy one that is likely to break if you look at it the wrong way....very weak set up, imo.

    I test a LOT of equipment, it's part of my job, and this flimsy little hollow alloy bolt is a joke. When you consider the amount of force placed on the hanger bolt, it would be a wise move for SRAM to strengthen this bolt so that it doesn't break so easily. Mine just snapped like a carrot!

    .........Not happy with this, at all.
