Sunrace 10-46t 11s has arrived: CSMX9X ETZ

I wonder why Sunrace does not make a 10-46t 11-speed cassette.

Steps could be 10 - 12 - 14 - 16 - 19 - 22 - 26 - 30 - 35 - 40 - 46

No gap larger than 20%.

- It would work with both SRAM and Shimano derailleurs
- Doesn't require cage modification
- Has a very useful range with no goofy gaps like the Gabaruk 42t to 46t one
- Works with mainstream XD driver unlike the Hope options
- Would be affordable unlike any other 11-speed cassette with this sort of range starting at anything other than a 11t sprocket.
- Would still be somewhat lightweight and compact unlike the dinnerplate 12-speed options or those starting with 11t with similar range.
- Less sensitive to set up as SRAM 12-speed.

I reckon they would sell bucketloads of them.

From what I understand, it is impossible to produce a 10t sprocket for a cassette designed for shimano freehub body, hence the 11-46t range instead.
I was talking about a cassette for the XD driver. Is perhaps a patent thing, that they would have to pay SRAM a fee for their cassette design? Or perhaps they reckon it would cost too much in new tooling?

EDIT: saw you added another post. Yeah possibly. Perhaps they are affraid to invest in it and proove there's a market, SRAM themselves do a GX 10-46t and steal their thunder. SRAM's interest is with making money with Eagle now.

Oh wait, just read your post properly. 🤦🏻*♂
I suppose they are focusing on designs for shimano freehub only at the moment due to budget restrictions? Perhaps when the company has more stable finances they will research and produce a cassette for xd driver.

Not Shimano compatible. The E-thirteen goes on an XD freehub.

Unfortunately with the lower cost of upgrading to 12 speed if you have an XD freehub most manufacturers are ignoring the 11 speed XD hub cassette crowd. It's expensive and difficult to make an XD compatible cassette and most people with XD hubs will just use SRAM cassettes. Also due to complexity there is not a good way to make them cheaper or lighter than SRAM does. It's a great freehub system that just hasn't garnered much aftermarket support.

My wife had the e-thirteen 9-46t when her park bike became her general use bike (switched from a GX 10-42t). When their cassette (parts) were not available for more than a month (probably due to production allocation to the 12-speed variant) she was forced to switch to Eagle GX to be able to take the bike on the holidays in the alps.

I like the 9-46t concept very much. Very useful range, compact, works with SRAM and Shimano derailleurs. There are also some serious drawbacks in my book:

- Way too expensive for a wear part for me personally (that's by far my major issue with it).
- Required quite a lot of effort to keep relatively quite.
- I rather had the big gap between 9t and 11t (like Leonardi does). That way you can use the 9t as an overdrive. Now the biggest gap was between 17t and 14t (21% in the middle of the cassette).

The whole one by thing is all nice and well but we bikers all of a sudden are spending a small fortune on drivetrain parts. My limit for a wear part like an one by cassette is around 100 bucks. I reckon a 11-speed 10-46t cassette from either Sunrace or SRAM would be below that with sufficient range for many bikers.

I would buy a 10-46 cassette in a minute if one were available! I have the E-thirteen 9-46 cassette and it works pretty well, but yeah-noisy and I was way more in interested in the 46 than the 9. a 10 small cog and closer spacing would be about perfect. I'm thinking about one of the SRAM 10-42 expando cogs from Wolftooth and others, probably a 44t. Expensive, since it only works with the higher priced cassettes, but it would be a better range for me.

11-speed and it's missing affordable cassettes

After many have found out (after it being downplayed by reviewers?) 12-speed is not without it's drawback's. It brings more weight, but most of all it requires more fine tuning to get it set up right. For many people the added advantage of the smaller gear steps doesn't outweigh the increased annoyance and time consumption of a finnicky gear set up. In fact, personally, I don't like too small gear steps even without the set-up issues.

For many 11-speed is not a station passed towards 12 and more gears, but genuinely a better solution. I think there is a considerable market for 11-speed, for people that want a widish range 1x set up, but just want a simple to set up, that is somewhat affordable.
What we're missing is logical, affordable wide range 11-speed cassettes that work with current equipment.

I'll list a few:


For Microspline:


Sunrace 10-46t
- 10-12-14-16-19-22-26-30-35-40-46
- 450g
- MRP: 80,-?

? 9-46t
- 9-11-13-15-18-21-25-29-34-39-46
- 435g
- MRP: 100,-?

For XD-drive:

SRAM GX style all steel 10-46t
- 10-12-14-16-19-22-26-30-35-40-46
- 410g
- MRP: 149,-

? All steel 9-46t
- 9-11-13-15-18-21-25-29-34-39-46
- 395g
- MRP: 169,-?

Add in a few lighter ones with a bit of alu in as well.

Instead we get expensive bullshit cassettes like Gabaruk's 10-46t with a silly 42t tot 46t jump or even worse KCNC 9-52t cassette with a 12t-15t jump (25%)...

I see no reason why not, but I'm no expert.

Also on:
https://www.universalcycles.com/shopping/product_details.php?id=99272

Thanks for the tip:

96 Euro for 491g

versus Garbaruk at 218 Euro for 306g

... decisions, decisions.
The Gabaruk 10-46t makes no sense to me with it's 42-46t jump (9,5%) as a result of using the same cogs as the 10-48t and 10-50t cassettes.

BTW this Sunrace also does this in a different form. It uses the same 10-28t cluster as the 10-42t variant. With the 10-46t you get a 28-34t jump (21,4%) which is a bit large. Though still acceptable for the price.

Hi, got mine last week, still haven't used it (need a bigger chain). Had the SRAM 10-42 (PG1150) and it was OK but I wished I had a lower gear a few times.

46t is alloy, the rest is steel. Gearing on the low blocks is similar to other SunRace cassettes, probably to cut some production costs:

Sunrace CSMX9 ETZ (11spd):
10-12-14_16+18_21-24-28_34-40-46
Sunrace CSMX9 ETY (11spd):
10-12_14+16+18_21-24-28_32-36-42
Sunrace CSMX3 TAZ (10spd):
11+13+15+18_21-24-28_34-40-46

Its been a few weeks, have you had much riding on the 10-46? any thoughts? what brand of RD are you using it with and did you need to fit a goat link etc?

Also, where did you buy it from?

The setup where I used the cassette is a 29+ HT with 3" tires, 1x11, 30t oval chainring with SRAM transmission (GX shifter and RD). So far did 2x the same 100km ride I did before with the 10-42 and also on a 29er fully with a 2x10, F36/22, R11-36, X5 shifters with a GX RD and Deore cassette.

In terms of quality it's on the NX/Deore-ish level. There was a small amount of chain rub when on the 28t cog (rubbing against the 34t) but with a screw driver between the 28t and the 34t and a bit of caution I got it solved.

For the new setup the chain needed to 2 extra links and B screw adjustment, no need for goat link. It shifts well up, going down there are a couple of single jumps that take a little bit longer but nothing special (probably needs better B screw adjustment).

The 46t cog really makes a difference to me, easier climbs comparing to the 42t cog and with the oval I go through the same climbs as easier as with the 22 front-36 rear combo on the fully (which is in theory an easier gear).

Got mine from bikepolis.com and liked their service.

HTH.

Last night I put about 8 miles on this cassette. I'd with the statements so far, especially shifting. It's a little clunky on the three big cogs. But I'm betting that improves as the cassette breaks in. Installation wasn't bad, just be sure to seat the XD sleeve and torque to spec. I replaced a very worn GX 11 speed cassette. I dropped into the 46 tooth cog on my largest climb last night and I was very glad I had the extra range. This cassette probably isn't for everyone. It's a 100g heavier than the gx 11, but I'm not concerned. I couldn't feel a weight difference, but I also swapped this on my trail bike, not my XC bike. I'll definitely buy another one whenever I wear this one out.

Nice...looking at moving away from GX Eagle 12spd to 11 spd so I can ditch the long cage der which has been a debris magnet for me.

Was planning on staying with XD driver so GX11 cassette was only option (42T big cog). This Sunrace 10-46 cassette sounds like a winner because I plan to install a Shimano M8000 11spd der (med cage) which can handle up to 46T big cog. This XL framed Kona Process 153 is already hefty so what's a few more grams!

I found a couple of online dealers that stock this cassette (CSMX9X.ETZ)
