Hatte erst eine unvollständige Cassette erhalten. Die Neulieferung erfolgte parallel zu meiner Rücksendung. Suuuuuuper!!!! Die vollständige 9er Cassette war ruckzuck da. Einbau verlief probremlos. Bei einigen Gängen springt die Kette noch immer leicht, das werde ich aber sicher beim Ausrichten auf dem Montageständer beseitigt kriegen. Geliefert wurde eine feste 7-Speed Cassette mit zwei kleineren einzelnen Ritzeln für die schnellen Gänge. Meine alte Cassette war aus 9 einzelnen Ritzeln zusammen gestellt. Da ich die alte Cassette viele tausend Kilometer gefahren bin und sie zwei Ketten und einen Rollensatz überlebt hat, wollte ich nicht einzelne Ritzel tauschen und "noch gute" weiter fahren. Hätte keinen Sinn gemacht. Nun habe ich alle Gänge neu für wenig Geld und kurze Arbeitszeit. Hoffentlich ist es wirklich ein Originalteil und hält wieder ewig, wie das Vorherige.

Passt perfekt auf mein Rennrad mit 9-fach Campa

My existing SRAM PG950 9 speed cassette was in an embarrassing state. If i used it any more, there would've been literally no teeth left on it. So I was very desperate to get hold of this and a new chain to go with it of course...With the current climate of bicycle parts being hard to get hold of, I was delighted to find this on Amazon and at a respectable price. In fact, when you look at how complex the teeth are, it's amazing they can sell them so cheap. If only I could say the same of chainrings!!Bottom line, it appears to be the genuine article judging by the packaging. It was dead easy to fit, which surprised the heck out of me. And it has been working great on my commutes so far. And I should say that it's nice to have slick gear changes once again, I didn't realise that it was the cassette that was making the gear changes to awful recently.Maybe I should buy another now so that I have a good spare available immediately when I need it! :-)

Seam makes great products that are of good quality !

Montage facile .Très solide.Et très belle cassette chromé

So far working well. So far only used for indoor riding. Got this for Wahoo KICKR indoor bike trainer that came with 11 speed cassette. My road bike is 9 speed so needed to replace 11 speed cassette on the trainer with this in order to use my bike on trainer. have ridden 600+ miles in a month on this cassette on the trainer and all seems good. Put new chain on bike at same time as installed cassette on trainer. May mount this cassette on bike when lockdown over and can start riding outside again...

Usually a reliable budget cassette. This one arrived without the smallest cog and lock ring. I was able to use the one from the old cassette as the middle gears were the most worn.

A quick and easy installation that restored the performance of my bike instantly. Shifts are crisp and reliable again, well worth the money.

Awesome. I love this cassette. I must tell you that I'm no bike expert. I replaced my worn out sram cassette on my mountain bike. The chain kept skipping on my old one and there were a couple broken teeth. This was an easy replacement. I used the lock ring off my old one as others had problems with the chain clearing the larger lock ring on this one. I also had to buy the special tool to remove the lock ring. No big deal. I love having the smaller range of gears. My old set had gears all the way up to 32 teeth. Which is totally unecessary unless you are doing some serious climbing. Now I have a lot more usable gears on my bike with this casette and no more chain skipping when I crank it hard. Also replaced my chain. My bike shifts smooth now even while I'm pedaling hard.

Low-end, Shimano/SRAM hub compatible 9-speed cassette. It's heavy, and designed for steel hubs. Works like a champ. Holds up to high wattage, and standing on a climb in the large gear.If you have aluminum or titanium hubs, or are concerned about a couple of ounces of weight, then you want a higher-numbered cassette with a large-gear spider.This is very wide range, pretty evenly stepped from 11T to 34T. This is great for a compact double crankset (34/50), giving a 1:1 (WHEELIES!) for monster climbs, and a 4.5:1 for powering downhill at 35mph.Since it's 9-speed, and such a wide range, you may find some of the mid spacing a little too much if you are mostly on even, flat pavement.If you do only hard, off-road climbs, you may find this is not enough (vs some of the new 42T pizza plates lately).END 2014 reviewEDIT 2017 - Subtracting a star because the description now says it has a spider, but it does not. A spider is a solid block of aluminum serving as the core for the biggest cogwheels. It reduces weight, and distributes the load so high-wattage does not dig into the freehub splines. THIS CASSETTE DOES NOT HAVE THAT. The description should not say it does.

Excellent quality for the price. The 12-23T has the six smallest cogs only one tooth apart which allows you to keep the same cadence no mater what the wind direction or grade change you encounter. It makes for a far better ride in mostly gentle rolling terrain than the usual 11-34T that works better for mountain climbing.

The SRAM powerglide series of cassettes is a very good BUDGET cassette and can give you excellent shifting performance for the price provided you have a good chain in serviceable condition (not stretched) and a good derailleur that is not bent, is adjusted correctly, is mounted to a derailleur-hanger that is straight and true and with a set of high-quality shifters/brifters and cables/housings. All this stuff needs to be in good condition, clean, lubed, and adjusted properly. One fly in the ointment and shifting and even pedaling may be noticeably and negatively effected.There are so many factors in problems with bicycle drivetrains that I have to read some of the less-favorable reviews for these and other similar cassettes with a grain of salt.Skipping, bad/slow/missed shifts, noises, and other problems can come from many sources.Often just replacing one part like this and expecting a magic bullet to fix all your ills is a bit short-sighted. If your old cassette was bad it's almost a certainty that the chain was bad too. Chains wear out faster than cassettes -but a worn out chain will grind away the favorite cogs of a cassette in short order. Replacing a worn out cassette and not replacing the chain will cause the problem to come back in short order. A worn-out cassette will also chew up a new chain in short order too!It's a good idea, if you are not an experienced bicycle mechanic to review Sheldon Brown's excellent articles on bicycle drivetrains and derailleur adjustments. Do a websearch for "Sheldon Brown Derailleur Adjustment" and just keep reading that page and other linked pages on the Harris Cyclery Website until you have more of the big picture of what you are up against here with modern indexed-shifting systems.If you are getting a cassette with a bigger largest cog for a lower low gear be aware that you may need to adjust your B-tension screw to keep the derailleur off of the cassette. This is a mistake a lot of people make and can cause serious damage to the chain, cassette and derailleur -even bend the derailleur hanger on the frame if it jams up and/or do serious damage to your wheel. Know what you are doing here please. Us bicycle mechanics really do not enjoy seeing people bring in mangled bikes and having to tell them that the cost to fix the mess will probably cost more than a new bike. Also, be aware that a larger biggest-cog may require you to run a longer chain or risk derailleur damage if the Large/Large cog/chainwheel combination is ever selected (not a good idea to cross-chain like this but still the chain should be able to do it should a mistake happen.)In my opinion the only downside of this cassette (and any decent bargain cassette for that matter) is a small-medium weight penalty. More expensive units will weigh much less -and may shift slightly better, but not too much -the most important thing in indexed shifting is a high-quality cable and housing followed by a good high-quality indexed shifter lever/brifter. But don't forget proper adjustment of all the components being essential also for everything to work well together. The skill-set necessary to do this is beyond many home bicycle mechanics, at least for the first couple attempts until they learn the tricks.The tools needed to remove this cassette are a cassette locking tool such as: a wrench capable of holding the tool, and a chain whip like this: . It's not a hard job to physically remove and re-install the cartridge. If your bike was working well when you swapped it should be fine with maybe a small adjustment of the cable to account for small manufacturing tolerances. If you put a bigger largest cog on you will need to adjust the B-tension screw for more clearance.BEFORE ORDERING: Check your derailleur rating by searching for it here on amazon to be sure that it is rated for a larger cog than you have. Most Shimano medium-cage derailleurs are rated for 27-tooth max but you can usually get away with 28. 30 might be iffy. 30+ tooth largest cogs really need to have a mountain derailleur with a long cage and not a medium-cage (or small cage) road derailleur.Sorry if this review seems super-long but there is a lot of material here to cover. Good luck with your new cassette, riding should be fun and there is nothing wrong with wanting your bike to shift well and be geared for your type of riding.

So far works well. Changed out my 53-34 to a compact shimano ultegra crank and this 11-28 cassette. I have ultegra group on my trek. This cassette is much heavier than my ultegra cassette but it has one higher and one lower teeth. The weight is worth it if you are losing it somewhere else. Like when I changed out my crankset I lost it there but gained on the back. The shifting so far is good. It's not a smooth but works.Can't beat that price.
