    First time I've seen a decently priced 12 speed cassette.

    Beware anyone who is thinking they can move from 10 or 11spd to 12spd you cannot.

    Its a different ecosystem that needs new hubs etc.

      Thanks for the warning

      It is starting to sound like razor blades. At what stage do you say this is getting pointless?
      Call me nostalgic, but maybe 9-speed was the sweet spot. Easy to adjust, and rugged. So what if my cadence is a few rpm off ideal?

      • AssociatedJonnySprockets @ Jonny Sprockets on 16/02/2024 - 20:19

        Oh for sure, I have 2x9 ultegra on my road bike on a smart trainer and the shifting is so smooth. However for 1x applications mountain biking, the 12 speed is great and really comes into its own.

        MTBs use a single chainring, more gears are very welcome.

      • ruprectaus on 16/02/2024 - 21:33

        lot of 1 x systems, so they can do away with the front cassette, derauiler and shifter, that alone saves lots of issues . However with MTB ebikes starting to dominate in the MTB community (I have one) you'd think 1x10 would be good enough and a beefier chain to help deal with lazy changes and lots of torque on the rear cassette. albeit I am no drive train expert.

        On a non ebike, I preferred 2 x 10. Lots more steep stuff in climbing with an MTB vs a roadie, need more gears.

      There are cassettes available for regular HD spline from brands like sunrace that will allow you to go to 12 speed without new hubs. However the hyperglide 2 system does work best with shimano cassettes and chains.

    Bad timing… I've just upgraded to CDs.

      Don't lie, you're still rocking 8-tracks.

    10-51. Wow. Must be thin. Probably have to change the cassette and chain every 5,000 km.
    Better off with a 9x3

    • AssociatedJonnySprockets @ Jonny Sprockets on 16/02/2024 - 20:24

      Perhaps, depends on your application. Many modern bikes are 1x only and won't even fit a 2x or 3x system. 1x also means a very solid derailleur with clutch system that wont drop chains, even on the roughest trails.

    • igerstep on 16/02/2024 - 20:37

      Sram does 10-52…

      The thickness of the sprocket is the same on 10-12 speed, 1.6mm, the bigger sprocket is just more inboard than the 11 speed. 9 speed is 1.78mm.

    Note that if you're not so fussed with a few more grams, the 'lower' series deore (6100) is largely the same, except more durable as it's made of steel.

      Only the 51t is alloy on the SLX version.

      • Telios on 17/02/2024 - 21:14

        That's actually interesting but still annoying that they can't just make a full non-aluminium cassette for once.

        Possibly the CUES stuff might introduce a full steel cassette for ebikes?

        • AssociatedJonnySprockets @ Jonny Sprockets on 19/02/2024 - 09:42

          The deore is full steel, as is linkglide 11 speed stuff for ebikes.

  • sssx on 18/02/2024 - 23:48

    How early is too early to buy one of these as a replacement? a year ahead?

      Wouldn't hurt to have as a spare, never seen them for this sort of price before. During covid they were near impossible to get.
