Carbon cranks with 24mm steel spindle

[Da11as]

Hey everyone.
I currently have a spider power meter with 3-bolt interface and 30mm axle. My current bike has BB86 so I have to run a bottom bracket with smaller bearings and have to replace it with another expensive BB relatively often compared to what I have on my other bike with BB86@24mm axle.
Do any of you have in mind relatively stiff cranks with 3-bolt mounting system and steel 24mm axle? I don't want to switch to another powermeter as I really like the one I have...
Seen several options on Ali, but most of them utilize alloy axle, which is not good.
Any advice?

Racework makes this crankset with steel axle and 3 bolt interface, though it uses alloy crank arms:

I haven't seen any carbon crank arm/steel axle cranksets on AliExpress.

These are the cranks I have actually installed on my GF's bike
They are fine, but a bit too flexy and heavy for my use...

In your shoes, I’d go for one of the DUB spindle options and switch out the bb

I checked into this a while back and could not find any 24mm aftermarket steel or Ti spindles that would fit the spline pattern they use. it looked more doable w/30mm

I have this crankset and it's a bit weird. Crankarms are bent in towards the frame a which reduces the q-factor but it's nearly impossible to set up with a front derailleur since the crankarm is rubbing on the derailleur cage in a big ring. After I installed it on my gravel bike with 1x it turned out that the crankarms are rubbing on the chainstays

Unfortunately, 1mm difference would not affect bearings longevity that much.

can you add some spacers? AE spindles are usually wider than 68mm std anyway

Are you sure? I have the super cheap goldix cranks these seem to be a very close cousin of; perfectly straight arms, completely parallel to each other. I had always assumed those racework ones were the same thing out of the same factory just with slight cosmetic changes to the code and a little price markup.
