Hi all,

I am trying to get a new set of crankarms for my power meter.
My current setup is using a 8-bolt torx screws to connect spider and a crank in a hidden bolt (HB) configuration.

Been wondering what are possible crankset arm replacement for a QuarQ spider?
Searching the internet was only able to find a Quarq Prime Power ready crankset - which is not sold separately unfortunately.

Second question is what are actual differences between a NHB (non-hidden bolt) vs. HB (hidden bolt) crank spyder?

I have been looking at the QuarQ NHB and HB spiders and from the pictures both appear very similar (only matter of spider rotation?).
Would that matter what crankset arms do you need to have?
Could one take a Sram crank arms (HB) and attach that to the NHB for example?

Thanks for any advice.
