I'm not sure there is any such thing in 10s.
SRAM make a 12-36.
https://www.chainreactioncycles.com/sra ... -prod55198It's a slightly higher-end cassette than HG50, using a spider for the 3 largest cogs.
The cogs are
12,13,15,17,19,22,25,28,32,36
This is versus
11,13,15,17,19,22,25,28,32,36 for their 11-36
so SRAM use 19-22-25-28, and Shimano 19-21-24-28
Shimano sell arbitrary top cogs (11-16t inclusive) with integrated spacers, for their 6600 cassette
https://si.shimano.com/pdfs/ev/EV-CS-6600-2370.pdfThis would make any top cog quite easy (I am not sure if you can go without these using separate spacers and standard cogs) e.g., 14t
https://www.sjscycles.co.uk/cassettes/s ... -1zd-1400dI'm not sure there is any such thing in 10s. 11-36 is a standard ratio, and CS-HG50-10 is made up of loose sprockets with rivets (and no carriers)
Not so. Shimano have been quite naughty with their 10-speed cassettes.
Essentially it is practice that everything above Deore/Tiagra uses carrier for the largest cogs. Deore/Tiagra and below generally don't use them
The first release at Deore/Tiagra 10 speed level was Tiagra CS-4600 which didn't use carriers.
The next year they brought out Deore 10-speed which did. At that point:
M771-10 (XT) with the top 6 cogs on 2 carriers of 3 cogs each
HG81-10 (SLX) with the top 3 cogs on a carrier
HG62-10 (Deore) with the top 2 cogs on a carrier (the 9-speed generation HG61-9 didn't use carriers, even with the same top cog)
4600 (Tiagra) with no carrier
HG50-9 is & was Alivio and does not use a carrier.
They then decided to rename HG62-10 11-36t to HG50-10 11-36t.
So at this point you had HG62-10 with a carrier and combinations 11-32, 11-34, 11-36, the latter also being known as HG50-10.
They then decided that 11-32 and 11-34 were also road combinations, and brought out Tiagra 4700, which would support them.
Since there was no functional difference between a 11-32 'road' and 11-32 'mountain' cassette, rather than call the new cassette CS-4700, they called it HG500-10. And it didn't use carriers. This allowed them to stop selling HG62-10 altogether, in favour of the cheaper carrierless HG500-10.
Because HG500-10 was in effect CS-4700, they didn't bother to make a 'mountain' 11-36 ratio for it.
So they had
HG50-10 with a 32-36 carrier
HG500-10 - with no carrier in road, and 'crossover' 11-32 and 11-34 ratios
But then they realised the market wanted a dinner-plate cassette, and came out with an 11-42t Deore cassette.
This was obviously massively heavy so they came up with a new design a carrier but I think in a different design, so it's nothing like the HG62-10. They decided to call this HG500-10 as well.
So the current state of play in terms of 36t cogs is that you can get a 32-36t unit from a Deore-level cassette, or a 28-32-36t cassette from an SLX or XT level unit. But there aren't any loose 36t cogs, though you could probably buy a third party one.
You can buy individual 28-32-36 sprocket units
https://www.bike-discount.de/en/buy/shi ... -10-633448Or buy an HG50/HG62 11-36 cassette and take it apart and use the 32-36 unit from that. Or probably find some third party 36t cog.
A 28-32-36 unit is going to expect a 24t before it, and a 32-36t a 28t before it. All 28t 10 speed sprockets should be ramped for a following 32t.
Hence:
HG500-10 12-28
