Can I use this for an Alfine 8 hubgear?
02 Jul 2022
Yes as long as you can use a matching hub gear sprocket for 3/32 chain.

Can you confirm, please, that this fits a Shimano FC430.

I am changing from Gates belt drive in order to lower the gearing.
Looks like that uses 104BCD, so yes this would fit.

Is this compatible with 3/32 inch chain?

And I assume the ID is 88mm?
Hi there,

You should be able to use a 3/32 chain without any issues. In terms of the internal diameter it is actually closer to 90mm than 88mm.
