Strengths: This is for the 9 speed model. It worked for a while OK.
Weaknesses: It developed movement, teeth broke off and the lockring came loose. I had only done 1100 miles on it.
Bottom Line:
This is awful, it broke after 1100 miles. I replaced it with a Shimano Alivio 9 speed model which works fine. Not worth saving a few pounds on as it will break long before a Shimano. Avoid like the plaque.

Strengths: The 11-32 9 speed casette came stock on my 2010 Access 29er and lasted 2000 miles before it was replaced - my chain was long over due for a change and wore it out. Even so, it shifted seamlessly until the end, never bent or chipped.
Weaknesses: None.
Bottom Line:
I've commuted a few days a week for most of this year with this cassette. The round trip is 23 miles, of which 8 miles is through some pretty rough trails (or lack thereof). I weigh in at around 240lbs, gear included and tend to ride with a low cadence. This cassette picked up and drug pretty much anything you could find in a bush including tree branches. It never bent, broke or chipped. It was always reliable and I never had any issues with it. Even with a trashed chain it shifted and performed reliably. Great product. Great value.
Frankly, at just $15, I just had to try it.I required a 7 speed(12-28)and couldn't find a Shimano, plus I was expecting to have to pay at least a hun as that was what I paid before I had stopped riding 10 years earlier. A year has passed and I havent experianced any problems. NO bending or breaking.The weight isnt excessive due to the plastic/polymer spacers and drilled holes.The shifting is decent with the ramps. I am a light rider, and ride mostly street but I see no reason to pay so much more for little improvement. At $15 you have only that to lose.

Strengths: None
Weaknesses: Chipping, bending, breaking teeth
Bottom Line:
Less than 300 miles and it has chipped, bent and broken teeth. I am riding this bike only on the street with a set of Shimano 2200 derailleurs and shifters and its disintegrating rapidly. Especially bad on upper cogs. If you buy a bike with one of these on it, have them change it immediately, if you are riding one check it immediately. Ride strong, Ride SAFE!

Strengths: Shifts great and very durable.
Weaknesses: A little heavier than XTR.
Bottom Line:
Great alternative to the status quo. Very durable and the ti nitride coating looks cool, too! Just replace your chains and these things wear like--well, steel.
Bike Setup: Bianchi Super Grizzily with Spinner fork; Sunrace/XTR drivetrain; Magura brakes; SDG I-beam seat/post, Syntace bar/stem; Kenda tires; Crank Bros pedals.

Strengths: Cheaper than shimano & sram. Lasted (still going) longer than xt and any sram. Shifts well. Durability is excellent.
Weaknesses: Hard to find. Not many bike shops know how to get the product. I got mine by calling direct.
Bottom Line:
I don't know if SunRace steped up their quality for 2004 but I had gone through 4 XT cassettes, chains, and chainrings between Dec 2003 and March 2004. I am a Clydesdale rider (a huge clydesdale rider at 270#) who races which means I ride the crap out of my gear. I was tired of dropping $220.00 every 3 to four weeks to keep riding. I made a few calls to SunRace about their products and bigger fellas. They sent me two different cassettes. I put one on each of my bikes back in March and they are still on there. Running, Shifting, and racing just fine. I have well over 500 miles on each. We're talking racing, road trips, and training. I have replaced my chainrings and chain at least twice and still haven't had to replace the cassette. BOTTOM LINE....THESE THINGS ROCK. I was supposed to gie SunRace a write up and send the cassettes back to them when they wore out but they are still kicking. I don't know if things have changed at SunRace but anyone who swore them off should give them another try.

Strengths: Shifts decently, despite what these know-it-alls who "really know how to adjust" their derailleurs say. Cheap. Nice finish.
Weaknesses: A tad heavy as far as cassettes go. Stigma from boobs that post bad stuff about it on MTBR.com when they are actually as clueless as they come
Bottom Line:
Listen, I have used all manner of stuff. These things shift just swell, especially for the price. I know those "If it ain't XTR it ain't squat" babies will look down their nose at you....until you catch them riding their NON-IMAGINARY bike equipped with Altus....which they bought at Walmart. Not everyone needs XTR...or XT for that matter. Sunrace cassettes are plenty tough...the cogs resist bending better than LX. So take that.

Strengths: Chrome plating on cogs, shifts very well for me, good price. I bought two for two different recumbents,, works fine on both.
Weaknesses: None that I know of, except whats listed on this board.
Bottom Line:
So far so good.!! My use is not real hard riding at all,,but I do shift under load,,and it works great for me so far. Based on what you z are saying though,,I am going to start inspecting it regularly.

Strengths: could be used as a fancy paperweight
Weaknesses: that it exists
Bottom Line:
it sucks, i only got about 120 kms out of this before it had to be replaced under warranty. The bike shop replaced it with a shimano hg cluster on so will see how that goes. The bike shop guy said these clusters are pretty varied in their quality, as they have less stringint Qualty control than other manufacturers, that is why they are cheap and fail more often than other brands.

Strengths: Matt finish
Weaknesses: Tooth Broke after 100 miles
Bottom Line:
Shamefully broke a tooth during some roadwork! XT seems much more durable - silkier gearchange too. The best thing about this product is that it taught me you get what you pay for, and it gave me an excuse with the other half as to why I needed to upgrade to XT.
