There are some carbon cranks on ali that look superficially similar to the lexon cranks (and other rebrands), just not quite the same (no indent on the show side, different axle and spider/chainring interface). I didn't find anything on these. Has anybody first-hand experience or are these already discussed somewhere?

Carbon crank arms, aluminium dub spindle, weird two-piece slide-on preload collar contraption, spider/chainring interfaces to the spindle (not the crank arm):




Cranks and axle seem to go for USD 150 and change regularly, but show up cheaper from time to time.
Suspiciously similar-looking cranks with the same type of axle (including preload collar and spider/chainring interface) are also sold as "Leese".

Theyre 400 g for crak and spindle, waste of money an material. Leese are 320 and much closer to a Cybrei copy

According to the product descriptions they'd be 30 g apart (400 vs 370). Where does the 320 g number come from?

Nvm, mixed up leese and sprill in my head

Those, I have seen as well, but they are different ... and 3x the  price.

Part of the motivation for my initial question was the low price the riros sometimes go for (just yesterday, 135 USD for the bare crankset).

I've been looking them up too, for 150$ with BB and probably a bit less on 11.11, 150g saving is tempting

I've been using the 24mm alloy spindle Riro carbon cranks on my road and gravel bike with no issue. Those ones are now going for sub $100 USD during the sales. I wouldn't mind trying this new one, but there aren't many chainring options out yet.

I didint think about the chainring interface...

So is this a proprietary spider interface?

I think it's a direct mount interface. There aren't many chainring or power meter options available yet.

Sure, the spider mounts directly to the crank. But it's not an existing standard, is what I mean. Obviously not Sram. Not Raceface or Rotor?
I'd be hesitant to bet on a new standard from some Chinese manufacturer that might be gone in a year or two.

I think it is Shimano direct mount. So I also think you can use the Xcadey power meter. But this combo will be a lot more expensive than the older Riro carnkset + P505 power meter.
And that is the reason why I decided to go with that last option last month.

I think that, too. Just for reference, comparison with a wolftooth shimano dm spider:




Sidenote: There was at least one listing of presumably the same crank (different branding, I think), where you could choose between 3 or 4 different interface types (meaning different milling on the axle interface, otherwise same construction). But that one was more more expensive.

This one? https://a.aliexpress.com/_EwklK5L

Yea, probably. Wasn't sure anymore which name it had.
