CSMX3 Pinion Cassette, Unisex-Adult, Black, 11-46 Teeth

This cassette is fantastic. I had previously used a OneUp Components 42-tooth expander kit and derailleur cage adaptor, but was having a terrible time getting my shifting to be crisp and accurate. The OneUp kit also has you remove the 15 and 17 tooth cogs and replace with a 16 tooth cogs. I personally did NOT like the 3 tooth jumps from 13 to 16 to 19 teeth. Plus the conversion cost me over $100. Enter this SunRace cassette. Installation is super easy and my shifting was instantly perfect. Tha'ts right - I didn't change the derailleur or cable or anything, but the shifting instantly improved. And it's cheaper than a single cog from OneUp. Since then, I've put around 800 miles on the system and it's still going strong. The cassette is definitely showing signs of wear, but it has maintained it's black color and is still shifting as smoothly as the day I bought it. And you get the same range as an 11-speed system. After buying this cassette, I honestly don't see the performance gain of the 11 speed system. I think I'll just stick with a system like this from now on. It's super cheap to replace, shifts just as well, and gives you the same gear range. I call that a win in my book. For reference, I ride around 1000 miles a year, race 4 enduros a year, and am quite performance oriented.

Install is very straight forward if you have the tool for removing the cassette. Seems to be of pretty good quality. Comes as a spider for the "lowest" three gears, a spider for the next lowest set of gears and the last four individual gears are their own separate units, with one aluminum shim/spacer. Very easy to tell in what order to install them in case they get splayed across your work space during the install.Surprisingly, a generic "RoadLink" (Wolf Tooth I think invented this thing) is included in the box! I didn't use it since I already bought a RoadLink a long time ago. It's a hanging bracket extender for the rear derailer. When I first converted my 2x10 to a 1x10, I ended up buying a 40 tooth front chainring, an 11-36 cassette and the Wolf Tooth RoadLink. According to them, they support cassettes up to 40 teeth... which is why I found it amusing that a clone of their product was included with an "unsupported" size!I'm happy to say that my short cage (or is it medium? I'm not sure, but it's not very large) rear 105 derailer seems to work just fine with this 11-42 tooth cassette using the RoadLink. I don't think it would be wise to use two road links together.... that would put a LOT of stress on your derailer hanger and probably look pretty stupid.We'll see how it holds up. I'm not exactly the strongest rider but when I removed my Shimano HG cheapo cassette to install this, the teeth all looked to be in pretty good shape even after about two years of pretty hard riding.

Got a new (2016) 2x10 shimano drivetrain and switched in the 11-42 cassette. Deore shifters, XT rear derailleur (the non-clutch with stiff springs), deore front cranks (24/38 front chain rings). Is quite a wide range, but the chain slack is within shimano's spec for the derailleur.Required a bit of fine tuning but works great, shifts well, though I try to avoid the large-large and small-small extremes.Now I can climb anything and still pedal 30 Mph on the downhills. Highly recommended.

Picked this up for my Giant Trance X that had the original Sram x7/9 11-36 cassette. Installation was much easier than I was thinking. I paired it with a new Raceface Narrow-wide 30T chainring. I can tell there is a very noticible improvement in shift up and down. It seems to hunt for gears less and there are even times where it shifts so smoothly I don’t even notice it. The climbing ratio on the largest gear is fine (.71) coming from .64. This will challenge me to get off the easiest gear and put my foot down on the gnarlier climbs. Very impressed with the quality of this and I think it will be on the bike for a while.

Replaced my 11-32 Shimano cassette with one of these. I had to get a bigger chain, but after adjusting the B-screw everything is working great, install was easy, adjustment was simple and now with 5 rides on the new setup I can say it all works really well. I like the increased range from the 42 tooth granny. if you have a 2x10 Mountain bike you might consider one of these for a little added range without spending a bunch of money.

Great cassette the black does wear off quicker then I expected.Update 11/7/18I have since retired this cassette, also these cassettes start to develop a click noise on the easiest gear, but a drop of tri-flow on the rivets will silence it for awhile, other then that it has been maintenance free and still has plenty of life left, I just upgraded to the Sunrace 11-46T Cassette

I went from a large ring - 32T 9 speed to 42T 10 speed, and single on the front, climbing is faster and I have a better range of gears, I even noticed the same weight of my old 9 speed cassette, compared with the new cassette with bigger rings

This is a great cassette. I'm on my second one. I purchased the first one to go up to 42T (from36) The beauty is that I can now afford to change the cassette more often. It wears the same as expensive cassettes. The first one lasted 3 years or 2000miles in MA mountain biking. I will buy again, great value. It shifts smoothly and is very quiet. You need a goat link if you are on a Shimano shadow. This is not my last SunRace.

Fantastic item. Works perfectly with a Shimano SLX mech, KMC Chain and a Narrow/Wide chainring. I was hesitant about converingt to a 1 x 10spd wide ratio set up. I shouldn't have been - it's fantastic. Trail riding is so much smoother and more fun without the hassle of switching between 3 front chainrings and shifting your way through all the redundant gear combinations. As soon as funds allow I will be getting another one of these for one of my other bikes. Build quality is excellent and the red anodised parts look very nice indeed. Don't know how long it's going to last, but functionally it's excellent at the moment and much, much cheaper than similar items from other manufacturers - so replacing it when it wears out won't be scary. Highly recommended

Hay que tener en cuenta que no todos los cambios traseros aceptan tanto salto entre dientes...... En mi caso, un xt normal de 10v pata larga sin ser shadow plus ni nada,montado en patilla de cambio direct mount ( cube reaction gtc) la cadena me tocaba y no fue posible montarlo. Compre un cambio shimano xt de 11v shadow plus y funciona perfectamente. Ojo que es posible que tengas que realizar un desembolso extra si tu cambio no funciona..... Aunque siempre sera mas barato que cambiar todo el grupo si lo que necesitas es un corona trasera de 46 dientes.

This cassette works fine and gives a great range. However the provided lock ring is junk and will not stay in place. Its come undone 3x on me now, and the final time I'd tightened it up to the point where I though I was going to break the freewheel. Gone back to my Shimano cassette and no problems again.

I was a little sceptical as to if this would work with my setup. Very easy to fit, same as Shimano. The only adjustment needed was to turn the B screw in all the way. I'm running an XT 2x 10, XT Long cage rear with a blackspire chain tensioner. Took it out today and hit a couple of good technical hills, and this operated flawlessly. I would defiantly recommend.

Cassette looks very nice well made. Just it's saying that is compatible with Sram i have bought the long cage and 116 links chain and it is impossible to clear the largest 46 one. Not even turning the b screw at max.
