Suntour XC Pro Granny Ring Spacer Width?

[MCA4President]

I've acquired some chainrings for some Suntour XC Pro cranks and realised the Granny Ring requires some spacers to set it in the right position. It's currently sat flat against the crank! I imagine I'll also be needing some longer bolts but that's fine, I can get those. Question is does anyone know the correct size spacers I'll need? My limited Google skills resulted in a figure of 4.5mm but thought I'd try to get a second opinion. Thank you.

8.3mm spacing has been mentioned for similar flat spider setups in the past (middleburn/race face).

I guess it also depends on if the granny ring is also flat or has its own offset to accommodate for.

I think they are the same as the ones for DX/XT cranks which is about 4.5mm iirc.

Thanks for your help

I might still have a pack of no's xc pro spacers somewhere.

That would be most useful, if not I'll trawl the depths of the internet for something to suit.

I'll have a rummage tomorrow. I've not seen them in a while but pretty sure they are in a box somewhere.

It's not actually a flat spider. (meaning the granny spacer does not sit on the same plane as the middle).

It more the normal shimano/suntour setup with the middle having a step under the middle bit. Hence the shorter spacers needed.
I guess you could measure this and take it off 8.3mm?
