Not the right fitment for the RS7's unfortunately! Thanks!

Have done very similar in the past. Pretty sure you would need either a 5 arm CD triple or 4 arm triple. The Incy spider sadly was never made to fit the RS7 cranks.

The vacant outer chain ring position could be filled with a bash ring.

Would a Middleburn Duo set-up work for you … not totally sure if that’s what your asking for?

Here’s a image of my 1993 FAT Chance Titanium (#13 Medium) showing Middleburn Duo system in use.

Still have the parts, if of interest can post some more detailed images + a price (as per forum rules) for chain ring spider combo.

GLWSearching…

I'm not sure the DUO would allow for low enough gears for this set-up. But I am curious to know what you would ask?

Let me assess condition first + remimd myself of chain ring size … which I think from memory could of been either 40-42 (think was 40 on mine) or 38 big ring + 32 granny ring.

Not expecting it to be in bad shape but wish to check details first!

Am just running a 38t front chainring now which works ok for my local terrain and riding.
