Any updates on your thoughts on these cranks?
Also, where did you manage to source them for $190? They go for 350 USD now on AliExpress.

he said he had AliX coupons available to reduce the price

Pretty cheap here:
I just found this on AliExpress: $211.50 | BIGROCK Carbon fiber ultra-light road bike crank 110bcd 160 165 170 mm 24 titanium alloy shaft 165mm
https://a.aliexpress.com/_mrceZsR

Should be around 180-190 with 40 off 200 coupon

Sadly this seller doesn't ship to the US. Anyway, I did pull the trigger in one. Paid $340 in total including shipping. Finger crossed I don't have to pay any import duties. I'll update here once I receive it.

Tariffs are baked into the price now.   

Does anyone have assembly and installation manual for the crankset?

To be honest, with such amount of washers provided, I expected something less straightforward

I have seen comments elsewhere that claim the crank tightening bolt is too soft for the recommended torque. Any experience with this? What is the recommended torque?

It was me talking about the bolt.

I've seen complaints about cranks unscrew themselves over time in Lexon crankset thread. Given that the construction of the BigRock cranks is pretty much the same and what I've received, they use the same bolt, which is made of some lightweight alloy.

Loss of tension is connected with material stretching and it is the early sign of the part not being up to spec which is also confirmed by some specialist in metal works whom I know personally. You made get away with it using locktite and being very gentle with the part bit given the size of the bolt and the specified torque, it's only a matter of time when it will snap.

I experienced rounding, cross-threading, loss of torque and snapping with cheap lightweight bolts and I don't think it's worth the risk, especially with cranksets where a malfunction may cause some serious incidents.

Bigrock+xcadey mounted on the bike together with new goldix CNC cassette. Nice weight savings, now time to test.

How is the shifting with the Stone chainrings?

Obviously Shimano is the clear winner. Absolute Black chainrings have been good really also. But Magene's PM chainrings are horrendous to front shift. Those Stone versions remind me of AB.

I am using those chainrings since last year and they're on par with dura ace chainrings they replaced. Really have only good things to say about stone.

I've installed the cranks and already have some miles with it. Rock solid, nothing to complain about really. I have other carbon cranks (Srams of different generations with different axles) and I don't feel any difference.

Bigrock Cranks + xcadey powermeter and Bigrock Skyline handlebars are going strong. Bike looks 🔥

Can you please give some info about axle length? What is your bike's bb total width? I'm a bit worried with my 91mm total, and there is no info about max bb width on Ali.
