Which cassette - 11-36

[boxrick]

I am debating between the following cassettes, I have just bought a GRX810 2x setup ( 48-31 ), with a matching front and rear derailleur and chain.

I am considering between the two cassettes:

( Sroad 10-36 ) ~ 270-280g ( Will need an XD compatible change at around £30 )

and

( ZTTO 11-36 ) ~ 235g
https://www.aliexpress.com/item/32981215634.html

The ZTTO is cheaper, lighter and doesn't need me to spend money on the XD adapter. Is there anyone with experience of these or some recommendations of similar?

[MayhemSWE]

Plenty of existing information on both, for example this thread:

ZTTO SLR cassette is light but not durable at all. SROAD seems to have poor tolerances on the lockring at least but otherwise work accaptably.

So from the sounds of it, both are not great options... Ideally I want (9/10/11)-36 shifting. Ideally good performance and happy to spend a little money. The only other alternatives seem to be the recon Ti and the Leonardi options. SRAM or Shimano don't seem to offer any 36 11 speed cassettes :/

I have the SRoad 10-36 cassette. The lockring was a smidge tight but nothing a couple of minutes with a file couldn’t fix. Shifting with an XTR Di2 SGS mech is clean with the occasional hiccup mid block. But then I am using a cassette that is outside the designed range.

I do have to ask why you feel you need a 9-up cassette with a 48 outer? What wheel size are you going to be using?

I’m using a 44/30 chainset hence the need for a 10-up cassette. 48 x 9 would be a pointlessly high gear. Even with 650b wheels you’ll be over-geared.

I have no desire for the 9, I would just take it if was all that was on offer which is why I listed all 3. Ideally I want an 11-36. I ordered the SRoad, if its no good I guess a SRAM PG-1170 or SunRace MS8 which both come in around 360g will have to do...

SRAM does.

I have one waiting in a box for the Cedar City BWR, but I bought it specifically for the Crusher in the Tushar (which was cancelled).

Any comments on shifting quality on SRAM 11-36 vs Sunrace 11-36 cassettes (11s)?

[gorkypl]

I am using Sunrace 11-36, zero issues in few thousand kms. Shifting quality comparable to Shimano, probably more affected by the cassette range than the technology used. Have not used SRAM so cannot compare.

The 9-32 3T Bailout has more range than an 11-36 and has nicely spaced faster gears. I run mine in exchange with a 10-42 for road-only gearing with more top end, using a 38t ring for both setups.

Like most non-lockring (i.e. e13-built) cassettes, it needs greasing of all contact surfaces to stay silent. Not a problem if you know it.

The trick with the SROAD cassette is to push your tool STRAIGHT into the splines. At any angle, it won't work. It's the same story with both my Abbey and park tool one.

[ultimobici]

Nope.

Used Abbey Tools one at work fitted that way but a new Park one did not. Checked with a vernier gauge to be sure and found it was physically larger.

I have an older Super B 1010 tool also fits the SROAD easily. The newer SuperB TB-1010 looks identical to the one I have, may fit easy as well.

Probably inconsistency between each of the cassettes then. I only have one of them but the Park Tool fits perfectly if you push it straight down.

How are you guys getting along with those SROAD cassettes? I'm intrigued by the 11-34t one.

I put my 11-34t 105 cassette onto my wife's bike since it was the only 11s cassette that could fit on her 10 speed hub. Now that I'm back on an 11-28t, I really miss the wider spread when I'm up in the mountains. Rather than pick up another Shimano cassette, I'm interested in the SROAD one which is claimed to be 100g lighter than the Ultegra 11-34.

I'm running Shimano Ultegra R8050 GS long cage derailleur if it makes a difference.

All the 11-36 options are MTB spacing, AFAIK, so they'll also fit on the 10 speed hub if that's a factor. My Sunrace 11-36 definitely needs a spacer on my 11-speed road hub.

Re: SROAD 10-36 don't have many miles on mine yet as my whole state caught on fire right when I got it. I also had difficulty with cassette tools, it's tighter than normal. But as for weightweenieism, it's definitely light:

Sunrace 11-36 bare 354.7g. Lockring 5.1g. DT Swiss HG driver and endcap 65g. Assembly 424.8g
Shimano Ultegra 11-32 bare 281g. Lockring 5.1g. DT Swiss HG driver and endcap 65g. Assembly 351.3g
Sroad 10-36 bare 281.9g. DT Swiss XD driver and endcap 46.7g. Assembly 328.6g

Since you're on Shimano drivers, you'll need to convert to XD, and of course it needs to be a hub that's possible to convert. More money but on the plus side, additional weight savings.
