Hi

I have a Orbea Wild FS H15 2020 and need to replace the worn cassette, the smallest heavy gears are worn out while largest light gears work fine.

Its this bike, but purchased from bikester

Cassette is: Sun Race CSMZ80 11-51t 12-Speed Metalic E-bike

Its out of stock but according to the link its compatible with Shimano so can i buy any Shimano 11-51t 12-Speed cassette and it will work or do I need to be careful what to buy?

Thanks for help

For 12spd Shimano only has 10-51t cassette which uses Microspline freehub, your current cassette seems to have standard Shimano freehub.

Related question: Is it possible to replace just the smallest cog individually? Seems mine started skipping recently.

And anyone know if these 10t cogs in stock anywhere here in the colonies?

Cassette: Shimano CS-M6100-12, 10-51T, 12-speed.

Thanks in advance,

It used to be possible, but the pandemic has made it very hard to get your hands on them.

And you can’t just buy the 10T individually; it comes as a set with the 12T. The part number for the set is Y1X498020.

Also FYI, the 14T and 16T can be had individually. The part numbers are Y1X414000 and Y1X416000, respectively. These are somewhat easier to come by.

FWIW, you can buy the sprockets on Ali too. Just search for "M8100 sprocket" and you will get some hits. Ive ordered from 0086bike Store and Chaser Store in the past without problems.
The small sprockets are interchangeable between M6100, M7100 and M8100.
