I’m getting the vibe this is a word salad thing for everybody. Maybe try this: The chain “knows” when to shift because of how the system/cassette is designed. Or even better: the chain “knows” what to do after the derailleur instructs it to move. Almost sounds like I’m describing a mechanical drivetrain…

The issue is that Transmission "knowing" the time to shift is marketing BS. There is no hardware to allow the drivetrain to know when to shift. Transmission puts enough pressure on the chain to shift at a shift ramp/ gate, but not enough pressure to force a shift before the chain reaches ramp/gate. The drivetrain knows nothing. This is why it's highly unlikely there will ever be a cable activated Transmission derailleur. With direct cable shifting, there is no way to prevent forcing a shift. The key to the shifting performance of transmission is completely reliant on controlling the limited...

I've always had a saying with bikes over 160mm of travel & are on DH casing tyres etc, 'if the trails require That kinda bike, they also require a shuttle/lift' I would rather take my short travel ripper such as a Fluid/rift zone/new trance x(which i own and damn its good) pedal those up and put the fun level much higher. Although, A long travel ebike.... solves all the problems🤣

Apparently September/October timeframe per Specialized Rider Care Customer Service.

The whole wireless only thing is really representative of what bothers me about the bike industry. Changing things for the sole reason to sell us something more expensive. Why would they not put a small hole in the head tube and in the chain stay, can fit little plugs in it if they arent needed. Its different than say 1x drivetrains or dropper posts where there is a clear and undeniable benefit. What is better about a wireless drivetrain vs a properly tuned cable one? We get rid of a $3 cable and cable housing and add a battery?
