Hi,
There are already quite some lightweight dub carbon cranks with aluminum axles, like Cybrei GP3 and skypivot ones.
There are also some seemingly rebranded ones, like the one from PassQuest, RockBros.
All of them seem to have around 2000~2500 CNY (on Taobao, a little more expensive on Aliexpress), similar weight, 320g ~ 350g (cranks + axle only).
But this pair, branded LEESE, only costs me 1000 CNY (excluding shipping/tax), and the weight seems more than reasonable.
(378g for 165mm).
Considering how cheap it is, as long as the pair doesn't creak during a ride, I'd call it a win.
And even if they are craps, I can still go trying another brand, with the same spider PM and chainring.
Despite the value, there is really nothing else included in the box.
No docs, no branded box, even no grease pre-applied to any threads.
