Шымано пошла в революцию https://bike.shimano.com/en-US/information/news/shimano-unveils-new--highly-compatible-ecosystem-with-shimano-cu.html. Новые группы CUES 9x...11x (на их сайте группа находится между аливио и зи), расстояние между звёздами кассеты одинаковое - т.е. совместимость по переключателям и цепям. Возможно для электровелосипедов? Как минимум кассеты указаны Linkglide.
например группа CUES U8000 https://bike.shimano.com/en-EU/product/component/cues-u8000.html
U6000 https://bike.shimano.com/en-EU/product/component/cues-u6000-11-speed.html

SHIMANO CUES: SIMPLICITY
By consolidating our 9-, 10-, and 11-speed component ranges with interchangeable components, including common derailleur pulleys, cassette sprockets and chains, SHIMANO CUES reduces shop inventory needs and simplifies the servicing process for mid-tier bikes.
This means bike shops will have the right parts on hand for servicing your bike.
SHIMANO CUES: VERSATILITY
We’ve created our most compatible and versatile component lineup ever, shifting away from our traditional trickle-down technology model to focus on the unique needs of the everyday rider.
The lineup features unified sprocket spacing across our 9-, 10-, and 11-speed drivetrains, so that components can be intermixed across a wider range of user groups and riding styles.
SHIMANO CUES: DURABILITY
As our most durable drivetrain technology, SHIMANO LINKGLIDE extends a component’s overall lifespan and delivers a smooth shifting experience for both analog and electric bikes.
With taller and thicker cassette teeth (вот этот момент смущает), providing additional surface area this mitigates the chain from skipping and distributes pedaling forces to prevent premature wear due to shifts from new and experienced riders.
