The question is whether it's worth buying a crank with an aluminum spindle. Does anyone have experience with it?

Why don't you ask the seller? A Geoid power meter crank weighs 676 grams when weighed myself, so it's not far off from the stated weight and that's with a steel axle. The Thinkrider carbon crank is listed as having a 24 mm titanium DUB axle. You see the point?

24mm aluminium spindles are risky, I've seen too many snap in two. Personally I would not use them, maybe for a lighter rider they can be ok

I ask seller but they didn't answer.

I would tend to agree, but i have a 210W FTp, never really push more than 700W, I am fairly confident I won't break one... lol

24mm alu spindle is not good?
Unless you have really poor power output or going for purely casual rides, don't buy alloy 24mm spindle.

Standing on the pedals with the cranks horizontal while going over some bumps can hit the spindle pretty hard., so you don't want to be on the heavy side either, regardless of your watts.

I asked the seller about the spindle material and they've sent me this.

They wrote to me that someone from their staff made a mistake in the description and the axle is steel.
Even so, crank is no longer available, at least from what I can see.

Hi guys, I just bought the power meter with Thinkrider carbon crankset. Does anyone have the reference number for the nut used to tighten the spider PM onto the crank?
Thank you

I put magnet on spindle and check it  ;D

What's wrong with it ? Have you asked the seller for a replacement part ?
