There isn't much out yet. Just the video really and the info in the video.Might have been useful to provide links to the info...maybe?
This is honestly the best info I was able to find (and not until 8:14), which didn't include links or weights.
The Box One E 9s is 290g so it's much lighter than what you can get with GX or NX. So if the price is reasonable, I'll be dumping Eagle for Box when it comes out.I saw the weights somewhere...but can't remember where. I don't think the cassette is all that light...around NX weights. They currently have a 9sp 11-50 e-bike cassette that is 650gr.
I'm mostly happy with my Shimano 12spd, except for some chainring options (which aren't Shimano's fault), on my hardtail.The new 12 speed Shimano groups look awesome, and I'd buy one, but I'm definitely interested in the benefits of a wide range 9 speed.
