Drivetrain to me and my riding friends is a consumable, most of which gets
replaced seasonally due to wear and tear - especially the cassette, chain and
chainring(s). SRAM 11 speed was a turn off due to the cost of the components
and the need for a new freehub body or rear hub. But Shimano XT 11 speed has
now dropped and it's compatible with the same old freehub standard as before.
If you want to run it 2x you can, and if you want a 1x system with a 50T cog
then the aftermarket has that covered as well. Fraction of the cost of
EagleXX1X01 etc. SRAM may have pushed the change forward, but Shimano has
delivered it to the masses now.
Great stuff. My first CK product was an oversized threaded headset over 20
years ago. When the NoThreadSet came out, they sold the parts to convert it.
It's still in service and going strong, only been repacked twice! I just wish
they would make fat bike hubs 🙁
