sunrace 11-50 cassette
This was a purchase for a friend who had an 11sp (11-42) drivetrain that was wearing out, and wanted to know more about the possibilities without a full drivetrain replacement. I researched and found this cassette would work with their current 11sp rear a Review from

Works great with roadlink
I am using this in a 1x10 setup with a 38t front chain ring + deore m591 rear derailleur (long cage) + wolf tooth roadlink and it functions wonderfully (presumably a sunrace derailleur extender would also work in place of the roadlink). I've only tested i

A good way of expanding gear range
I wanted to improve the low gearing of my bike. I opted to use this cassette together with a long cage mtb rear mech, instead of installing a triple crankset. I found that one of the sprockets didn't slide onto my wheel's freehub body properly, but the re

Cassette that does the job... Well!
Although it seems a tad heavier than the big brands, this cassette has everything Im looking for. Since I dont own any 11-36 10 speed cassettes from other brands, I cant confirm SunRace is actually heavier! I purchased this cassette due to its competitive

Seems to work fine
I had a 29er setup with a 26T front and 10-42 Sram cassette on the back. The carbon Sram cranks only lasted a just over a year. The soft aluminium axle wore away when the bearing in the Sram PF30 BB seized and then 2 of the bolts holding on the chain ring

Great Value cassette.
Sunrace cassettes are such good value compared to the more well known players (Sram and Shimano), but the quality is still very good. Some people say that the gear change is not quite as good with Sunrace but I can't tell the difference and I have Sram on

Cassette is solid and not noticeably different in quality/solid feel from 105 it replaces. Doesn’t come with the fancy red lockring, just standard black, which may be an issue for some, but still looks good and works smoothly. A good alternative to shiman

Surprisingly good
I’ve always used Shimano for my MTBs since upgrading to indexed shifting a long time ago. I thought I’d give this a go as a 1x conversion for my 2x XT drivetrain. I was expecting hesitant shifts and also to feel the wide spacing on the lower end of the ra

Ok but not on par with Shimano
The MTB I built has a stealth look (all black) so when I saw this cassette in black I had to try it just to benefit the aesthetics of the bike. It was a straight swap for the silver Shimano XT cassette and slight derailleur adjustment was all that was nee

Decent option without breaking the bank
Was a little hesitant about buying this cluster but decided to take a chance. Was a better option than going back to the aluminum 42 tooth ring from One up, was always suspect of wear rate. Also by the time I paid for a new cluster then did the One up rin

Loving my new drivetrain
Finally converted my Trek Remedy 8 (2014) from a 3x10 to a 1x12 (I run a 34 tooth chainring up front). This cassette provides pretty much the full range of gears as my old 3x10, though the steps between the gears are obviously a bit higher. Nonetheless, t

Cheap way to get a wider range
Sunrace cassettes offer good value for money, and also easy way to increase the range of your drivetrain. They are very durable, however at some weight penalty. I have used this cassette on both a gravel bike and a hardtail XC bike without hassle.

Don't buy an expander ring - get one of these cassettes!
After making the decision to move to 1x10 on my XC race machine, I was torn between buying a 40T expander ring (and keeping my 11-36 block) or going for a full cassette. I'm glad I took the plunge on the Runrace 11-40. I was initially dubious about making

2x10 to 1x10 conversion
Went on a bad habit 27.5 + bike to convert it from 2x to 1x. Got a chain and 34 tooth narrow wide chain ring at same time. It was a successful experiment. I have since gone to a 30 tooth oval up front and plan on a box2 with a better range cassette. Then

A brilliant upgrade for my Trek Checkpoint
This replaced the standard 11-32t cassette, really increasing the versatility of the bike for touring and riding off road. Works brilliantly with the 105 derailleur IF a small derailleur extender is installed, dropping the derailleur a couple of cm. These

Sunrace 12 Speed why not!
Received in a timely manner as do all Pushys orders. The Cassette its self is as I would expect, fitted easily, shifts well most of all its silent. I find the range perfect for the areas I ride (Sunshine Coast Qld). All in all no reason why not to purchas

Gives great range without breaking the bank
I used this to convert an old 3x10 to a 1x10 and it worked a treat. Missing a single cog is barely noticeable compared to my X01 1x11, top speed isn’t that important! I paired it with a blackspire snaggletooth 34 up front using a KMC chain and an old (n

Works great with mods
Awesome cassette!! I love the large gap in the lower gears. I came from an 11-34 cassette and replaced it with this 11-40 one. You might need a longer derailleur or spend some time modding because of the large 40T sprocket that's too large for the stock d

Shifts without a fault with 8spd derailleur
Installed the 10spd 11-40 on my Redux 1 which is all 8 speed with a JGBike 22mm Link extender, a KMC 10spd chain, and Microshift 10 speed R10 road levers. All works flawlessly on the 8 speed derailleur. Try using your old 8 or 9 speed derailleur if you ha

The options for finding a cassette with this range are very limited, and as a rule quite expensive, but this unit was relatively affordable with nice preparation and a quality and finish that were impressive for the cost. I was able to set up a custom 1x

Even ratio spread, reasonable weight
I replaced an original almost worn out 11sp SRAM 42-11 tooth cassette with this Sunrace 36-11 after 17000km, as I wanted smaller jumps between gears, and almost never used the 42 tooth sprocket, so was able to save a bit of weight in the process. It works

Great wide range cassette for the price
I am using this on a 1x11 cyclocross bike. I use different cassettes for different applications. I use a narrower range for racing and the wide range 11-42 for riding around town/gravel/trail riding. It shifts just as well as the "Big S'es" cassettes at a

The Sunrace 12 speed cassette is excellent!!!
I bought the Sunrace 12 speed cassette in order to get a wider gear range that I didn’t have with my 11 speed Shimano set. Install was easy and I do recommend getting at least the SRAM GX 12 speed derailleur as the Shimano derailleur can’t run through the

Great replacement to Stam
I just set up 2 different bike with the SRAM eagle gx 1x12 and didnt have an XD hub. SunRace makes this cassette to work on a standard rear hub so anyone pretty much can have a 1x12 without having to replace their wheel. Shifting was great but takes a bit

Replaced an 11 - 34 Shimano with the Sunrace 11 - 42 when going 1 x 10. Once I'd got the derailleur in the right place the shifting was as good as I'd experienced with either Shimano or SRAM products. Done a few rides with it now and it works well and cle

Great product, works better than an expander ring.
These are the best way to go wide range on 10 speed. However, if you want the shifting to be as good as with a regular cassette, get the OneUp Rad cage as well. These are not too difficult to fit & OneUp give great instructions, but if you don't totally t

Nice gears at a low cost
Really great deal! I think the black paint will wear off quickly. Black cassettes are a total fad...but hey, it was cheaper than silver. This is a fairly light, equal quality cassette to Shimano or Sram at a much lower cost. I'm sure it'll last a good lon

Amazing for the price that it was. I have 32t chain ring on the front and runs great if you have the power for it. Would recommend having a 30t or smaller chain ring of the front with the 11-42t cassette on the back for other riders but other than that it

Works as advertised
'Dinner plate' sized 10 speed works well. No complaints. I have one on my 2 x 10 bikepacker full rigid MTB, and this one now on my 1 x 10 dually. Easier solution than what I was doing previously - modifying a 11-34 with a single 40 or 44 big cog.

Great looking cassette with the all black. It was also the range I was looking for with a great price. (11-42 10spd). I haven’t riden it yet but once I’m installed it on my hub I could tell how smooth and dialed it’s going to be. Highly recommend!
