    All of the free hub biting damage issues can be fixed with steel ribs/inserts on one or more of the splines though, like on some Novatec (and American Classic?) hubs, in engineering terms it’s a non-problem as it’s so easily fixed, I can only assume it’s a patent issue stopping other manufacturers adopting it for their alu free hubs.

    As do spiders by spreading the load … but then the cogs themselves can’t be replaced individually so a bit swings and roundabouts.

    Nothing (other than cost) stopping individual sprockets being on an alu carrier to spread load and still be replaceable. The higher end Campag cassettes have carriers with pairs of sprockets on, which is almost close enough, but then they also have deeper splines on their freehub/sprocket interface anyway…

    Shimano ones used to be bolted together with long bolts with a tiny head.

    if they make them to be on a single carrier it wouldn’t be a problem at all

    Good point, like in the days of old.*

    Folks on here constantly moaning about new ‘standards’.

    Folks want a new standard that is more expensive for no benefit.

    Bizarre.

    About half the sprockets on the XT 780 11-36 were actually replaceable (and at a fairly reasonable price)
    If you then used an expander then that was also replaceable.

    But its down to cost…. the bigger sprockets are heavy in steel and fragile in alloy and presumably horrendously expensive in titanium so do you want a cassette that’s all replaceable but costs £200 or semi replaceable and costs £60 ??

    Equally the Novatec freewheel replacement including bearings is £35-£40 so cheaper than a cassette…
    (Prices for the D772 on my kids bike)

    In many ways its like BB’s … the Deore External is £15 ish (less than new bearings for a Hope one) so its a matter of light/strong/cost again.

    As Nober say’s we all moan about forced new standards … so if SRAM/Shimano are essentially defacto standards then I’ve no problem with other companies making non-standards… (for debatable value/benefit)
