Product Description

To the casual observer, the SRAM XX Rear Derailleur might look just like a SRAM X.0 rear derailleur. Far from it. While it does share a great number of details, the XX Derailleur is quite different.For one, the full carbon fiber cage is built specifically for its role in the XX group to accommodate the narrower 10-speed chain and 36t cog. The XX Rear Derailleur is also the first SRAM mtb derailleur to use their Exact Actuation Technology along with the matching XX shifters. While their 9-speed groups have long relied on a 1:1 pull ratio, designed to be more tolerant of the muck and grit associated with mountain biking, the Exact Actuation in the 10-speed XX group takes the performance to another level by ensuring a perfect and consistent shift distance between each gear, all the way across the cassette. And like the rest of their rear derailleurs, the XX model is designed for direct cable routing, eliminating the typical loop of excess housing necessary with other derailleurs.The XX Rear Derailleur is feathery light, mostly due to the use of high tech materials. We mentioned the full carbon fiber cage, but just as impressive is the combination of the forged magnesium and 6061-T6 aluminum inner and outer links, the forged 7075-T6 aluminum B-knuckle, and the use of aluminum and titanium for the hardware and cage spring respectively. It's apparent that no material was worth overlooking to create what we feel like has been their finest offering to date. As evidence of their quest for perfection, they even used their Blackbox ceramic bearings in the pulleys to eliminate excess drag when you're trying to go as fast as possible.The SRAM XX Rear Derailleur is designed to work with SRAM's 10-speed 11-32 and 11-36 cassettes paired with a double crankset. It's available with two cage length options -- Mid and Long. The mid length cage is best suited for use with hardtails and single-pivot suspension designs with minimal chain growth throughout the range of travel. The long cage model can handle the greater chain growth potential that many full suspension trail bikes exhibit. If in doubt, go with the long cage version. It was once the only option anyway.Click here to save when you purchase an XX build kit.

Strengths:    Excellent shifting

Weaknesses:    Chain skips off tension pulley

Bottom Line:   
Like some other reviewers, I've had the problem where the chain tends to skip off the tension pulley and ride between the pulley and the inner cage. This damages the cage and makes it impossible to rotate the pedals backwards, which one occasionally needs to do on the trail. This was very annoying but I have found a solution that so far works perfectly: tie 2 large cable ties around the inner cage, effectively reducing the gap between chain and cage. When the chain tries to skip off, the ties guide it back on. I have pictures here which hopefully clarify what I mean:

Other than that, the shifting is excellent but I would say not good enough to justify the high price (mine came with the bike, so I had no choice).

Strengths:    I have an Ibis Mojo HD that came with X9. Thought I'd upgrade and changed out the shifters, crank, cluster, and rear derailler to Sram XX. Amazing shifting! Been a Shimano XT and XTR rider my whole life and was just knocked over with the clean crisp shifting.

Weaknesses:    Been riding the XX for about 2 months now. Yesterday went on an XC ride, stood up to crank up a hill, and broke the cage in half. The broken section sucked up into my chain and cluster and locked my back tire. Had to take off the chain to get the broken bottom half of the cage out of my cluster. Coasted back to the parking lot. Called SRAM this morning about warranty. Very nice guy, but I'm out the $200+ for the derailler since I bought it from an EBAY bike store. No Warranty and VERY VERY Fragile derailler. I'm an XC rider and 58 years old. God only knows what happens to these derailers with a 20 something all mountain rider on very technical trails.

Bottom Line:   
Very good/incredible shifting! Very fragile cage! Warranty from SRAM looks highly unlikely. When SRAM gets the cage figured out (get rid of the carbon fiber) this will be an awesome derailer. They also need to figure out how to reduce the retail price. Too expensive.

Note to buyers on EBAY, I just received a call from SRAM, if you do not buy from a legitimate bike store, you are buying product without a warranty.

Strengths:    Upshifts

Weaknesses:    Downshift vague and skippy.

Bottom Line:   
Fragile cage plates combined with the slack spacing means that chain can derail and shear plates if you ride on anything remotely technical. Not worth the money, at all...

Strengths:    Can't think of any.

Weaknesses:    Weak, fussy, overpriced,

Bottom Line:   
I have had the same problem with the lower pulley as the other guys in this review. That is the lower pulley wheel and cage has too much play and the chain derails from the lower pulley. If any one from Sram reads this I would like to talk to you about replacements. I've tried the local bike shops and they don't want to help and your website is impossible. It would be nice to have a list of your local reps.

Strengths:    ultra quick/positive shifts, lt.weight

Weaknesses:    Cost too much

Bottom Line:   
I went with the SRAM stuff because I know it shifts good and its very lite. I was trying to build up a full suspended 29er XC racer that I could trail ride too. The derailleur has been flawless so far. I was a little concerned about reliability of a lite derailleur like the XX but so far so good. All my friends that have ridden it comment on how positive it it shifts

Strengths:    None

Weaknesses:    Stay away from SRAM XX rear mtn bike derailleurs, complete junk. The cage is made of carbon, to save 5 grams I guess? Well the problem is, because of poor design, the chain comes off the bottom jockey wheel, and then shears the carbon cage right through. This is a commonly known problem, and has happened twice to me.

Bottom Line:   
SRAM needs to go back to the drawing board on this one, I'm sticking with Shimano for now as they have way way way more experience and are not such freaks about weight.
