The SRAM S1000 Eagle Transmission is the least expensive wireless electronic T-type drivetrain with similar performance to GX. To get one, you have to buy a new bike, but it does introduce another cassette option for aftermarket buyers.
The TRP EVO 12 is a complete 12-speed mechanical drivetrain that features distinct tech like the Hall Lock that buyers won't get from Shimano and SRAM.
