As this ship has definitely sailed by now (and I'm the only person left on this planet whose knees aren't compatible with cowboy-stance cycling), this is just some unrelated rambling: At this point I couldn't care less about the last 20 g shaved off of an already crazy light crank set. Moderately lightweight is fine, just give us some narrower options instead. 150 mm on a road bike?! That's crazy.

Seem to be the standard for these raft of Chinese cranks 149-151mm

Many of the  300-320g cranks appear to be the same model, supposedly from Carbonking (vs. the ones with the little sculpted intent supposedly from Apex that are usually a little heavier), but this 290g model seems different to me than either. While I understand this is a direct competitor to the Elilee Trecento, I would have been more interested in a lighter dub model. While I'm also fine with 150mm on my gravel and road bikes, I would also prefer some narrower Q options, even if it meant that the crank length maxed out at around 165mm.

Found the alibaba page as well https://www.alibaba.com/product-detail/DFS-Lightest-286g-Carbon-Fiber-Crank_11000028440011.html

Crank arm shape is new compared to the majority of available options. The DS crank-spindle interface looks to have remained the same though, unlike the x-trecento which requires a proprietary tool. The NDS is new, almost looks like it could be removable? Nice to see stiffness wasn't compromised either, after moving to a 24mm spindle. I might be in the process of finding out I need a narrower q-factor than I always thought, so I'm also a bit apprehensive about that.

Are you sure an aluminium dub spindle even gets any lighter than a proper, non-waisted, 24mm spindle? Both weight basically the same on the Elilee X310. Every case of the ti spindle weighting more that can I remember was with a waisted spindle.

Apparently this 290model is from the same manufacturer as Cybrei
Ceniit. Tagoola are selling these Cenit cranks on Aliexpress
