There's a bunch of news hiding in what looks like plain sight in Ltwoo's updated catalogue:

On the MTB side, there's a new 'T' series of shifters/derailleurs with clutch rear derailleurs. These are across the range, going from 8-13 speed. There's also the semi-electronic shifters as has already been shown.





For gravel, there's the new shifter shape available in 1x12, with brake calipers (as has been leaked previously). There's also a new rear derailleur with a clutch that comes over from the MTB line, but has been redesigned to take a barrel adjuster which is across the range from 9-12 speed. All other components remain the same.



On the road, the new shifters are available in a 2x12 version, with aluminium or carbon blades.



No separate brake caliper listed so I assume it's the same as the gravel one. No other new road components, and the new lever shape is only seen on the 2x12 hydraulic content, everything else remains the same.

I'm running into the same issues with a lot of items I wanted to get but won't ship to Canada.

Anyhow, I've got this YBN chain in my cart for a while now. Hope this helps!
