$39.00 | | Purchased At: | LBS | | Strengths: | Shifts ok, looks nice | | Weaknesses: | Seems to be made of very soft metal; wears quickly | | Similar Products Used: | Shimano LX, XT | | Bike Setup: | Much loved Turner Burner with lots of miles on it. | | Bottom Line: | The drive face of the rings flattened and widened from chain pressure. Cassete was installed with new chain and crankset, but was still badly worn after about 800 miles. I replaced it with Shimano LX for almost the same price. The LX is lighter, and so far has lasted more than 3 times as long. The SRAM is probably worth it's price, but the LX is a better value. | Value Rating: Overall Rating: |

$60.00 | | Purchased At: | LBS | | Strengths: | Sorry, but really nothing good to say about it. | | Weaknesses: | I experienced exactly the same thing as several other reviewers - a nasty clunking in one gear. I took the cassette off and reinstalled, checking the lock ring with a quality torque wrench. Unfortunately nothing worked. Eventually I scrapped it and went back to an XT cassette. In installing the XT cassette I noticed that the XT has its main body rivited together much more securely than the Sram. I don't know if this played a factor, but the Sram just felt cheaper and flimsier. Also the Sram lock ring was not as substantial as the XT. | | Similar Products Used: | XT | | Bike Setup: | Mostly XT | | Bottom Line: | I have to give this a don't buy recommendation. I don't want to completely trash this cassette because it remains a possibility that mixing a Sram cassette with an otherwise all Shimano setup made for some problems. However, Sram markets it as Shimano compatible, so it should be. My advice: stay away. | | Value Rating:Overall Rating: |

Date Reviewed: July 18, 2007 | | Favoriate Trail: | Saratoga Gap | | Duration Product Used: | Less than 1 month | | Purchased At: | Came with bike | | Strengths: | Inexpensive. Robust. Wide gear range. | | Weaknesses: | Heavy. Play in some cogs. | | Similar Products Used: | Shimano XTR, STX-RC | | Bike Setup: | Chumba XCL, Fox TALAS RLC fork, Fox DHX Air 5.0 shock, Shimano/SRAM drivetrain mix, Truvativ Team OS bar & stem, Thomson Elite post, Specialized Avatar Gel saddle, Avid Juicy 7 brakes, unidentified wheels, Maxxis Minion tires | | Bottom Line: | The 11-34 version of this cassette came with the standard Chumba build kit. It's a stack of individual steel cogs with the 7 largest held together with pins and a screw. The cogs seem to be well made.
It shifts OK with the SRAM X.9 derailleur and shifters. But on every ride, I experienced some play in a couple of cogs that felt like "clunks" while pedaling, even after double-checking the lock ring torque. This behavior isn't in keeping with a $3K bike build, IMHO.
The play and the 400+g weight turned me off of this piece, so I got a Shimano XT M760 cassette on sale to replace it. I'll keep the PG-970 as a spare. | Value Rating: Overall Rating: |

Allthough it is not perfect, I can get 1500 miles out of it before it begins to skip, bend or cause the chain to slip. They dont develop play on the freehub like the XT did either. That being said, cassett, chain and chain rings are spares I always keep around. Drive chains wear. | Value Rating: Overall Rating: |

Date Reviewed: April 12, 2007 | | Duration Product Used: | 6 months | | Purchased At: | Internet retailer | | Strengths: | shifts well, looks good, reasonably light | | Weaknesses: | wears fast | | Bike Setup: | 11-32 970 cassette, sram 971 chain, x-7 rear mech, x-gen front mech | | Bottom Line: | really smooth shifting cassette - shifting to larger cogs is particularly nice - shifts nicely under power, which is a big bonus when climbing.
haven't had any of the problems with bending cogs - but the 970 cassette has bigger cutouts than the 950 cassette (saves about 30g). might be too weak - always assuming that people are doing the lockrings up to the correct torque (",)
downer is the fact that this cassette has worn fast - it's only lasted 9 months and one chain (the chain and the cassette gave up around the same time) - my chain started skipping on cogs 4,5,6 (which are the ones I use most) and had just reached 0.75% stretch - no point changing just the chain that would make it skip worse.
I noticed that the cassette doesn't rust - wondering whether they're made from stainless? If they were then it would explain the wear pattern - the edges of the teeth are all flared outwards on the badly worn cogs - unfortunately stainless while it is very hard, is actually more malleable than carbon steel - it's harder to drill or cut, but is easier to bend or stretch - which might explain the problems with bending cogs, and the wear pattern on my cassette.
have replaced it with a 950 cassette instead. If it's going to get fried in 9 months at least it will cost me less - and on my steel rig I can get a 30g weight saving cleaning out my belly button fluff.
gets 3 chilli's for wearing out quick and a 4 overall coz it's nice while it's nice | | Value Rating:Overall Rating: |

$50.00 | | Purchased At: | ebay and installed on new trike | | Strengths: | Nice gear range
Good shifts
Easy install
Easy cleaning | | Weaknesses: | None found... Bike factory didn't tighten fully so the screw/pin came loose. No harm; no foul. Just reinstalled the screw and all was good. | | Similar Products Used: | Note sure what Specialized uses... but whatever it was, it wore out quickly. | | Bike Setup: | Actionbent Tadpole Trike; 26" drive wheel. | | Bottom Line: | I upgraded the trike with a SRAM DualDrive and chose the same cassette that was on the original wheel (11-34). The price was right and the performance was good for a road trike. Never skipped a cog and always shifted smooth up and down. At 240# and climbing 12+% grades, this thing is hanging in fine under my masher feet. I'm running a KMC Z9000 9 speed chain over the cassette. Took the original PG-970 cassette apart to clean it when I put the DualDrive on and it cleaned up good as new with over 500 miles on it. | | Value Rating:Overall Rating: |

Date Reviewed: February 7, 2007 | | Duration Product Used: | 6 months | | Strengths: | Fairly light and less expensive than Shimano | | Weaknesses: | Large cogs bend | | Similar Products Used: | Many different cassettes | | Bike Setup: | Scalpel, Fox F100 rlc fork, Sram grip shift | | Bottom Line: | This is the third Sram 11 x 34 cassette that I've bent the 2 largest cogs teeth on. They bent after between 3 and 15 rides. This with fresh chains and proper adjustment. I'm an older 165 pound rider with moderate power so these cassettes were not stressed. I'll be going to cheaper, heavier cassettes when I need a 34, otherwise I'll run 11 x 27 ultegra which should solve the problem. | | Value Rating:Overall Rating: |

$34.00 | | Purchased At: | LBS | | Strengths: | shifted well, low price, looks nice | | Weaknesses: | Worn out after 6 months of use. | | Similar Products Used: | Sunrace JuJu 11-34 | | Bike Setup: | Ironhorse Warrior, Raceface Evolve X-Type Cranks, XT FD and RD, LX rapidfire shifters, CN-7701 chain. | | Bottom Line: | This thing shifted well, but in my opinion wore out too fast. I am pretty much a clean freak when it comes to my dirvetrain, so I am sure that the quick wear is not a result of dirt and grit build-up. It was better than the SurRace JuJu that came with the bike, which I managed to wear out in about 3 months. I suppose that I am a little on the large size, weighing in at 190, and I do put quite a few miles on my bike, so those may be extenuating circumstances. I am replacing with an XT 760 cassette, which is roughly twice as expensive. Shall see how the XT lasts in comparison. | | Value Rating:Overall Rating: |

| | Bottom Line: | I"ll have to disagree. I"ve used SRAM casettes for a long time now and I"m always amazed that people don't like them. I've worked as a mechanic for 12+ years and I have used Saches/SRAM cahins forever. I have had nothing but bad luck wiht Shim. chains. My point is that the chain is going to determine how fast the cassette wears out. The sram chains don't streach as quickly and thus the cassette's last longer. Honestly I can't beleive Shimano sells any chains at all. I could gush about SRAM chains forever. | | Value Rating:Overall Rating: |
