Campag C Record Triple?

You could probably make one like the NR by drilling and tapping the arms and adding spacers for the smaller inner chain ring. I believe when people first did this to the NR it was just done by people that knew a machinist and had them do it. I'm pretty sure it would be fine as there's more meat to the arms than a NR crankset. I bet it would look sweet.

The more modern shape might not be very flat, which could present complex requirements for the tapping and spacers.

I mounted a 110 ring straight off a 130 ring in order to make my starfish compact;

It suddenly struck me that as a retailer, I could avail myself of a staff purchase price of a Supacaz bottle cage- because unlike 99.9% of the bike stuff i order, its actually for me!View attachment 855290
The outer ring was a narrow bmx item sold with drilling for 130 and 110.View attachment 855438

The mavic chainset had a spacer holding off the inner ring with the chainring bolts threaded into a blind socket in the back of the arm.

I used these spacers to hold a 34 tooth ring off the 110 holes, with single chainring bolts flush holding the outer onto the spider

One day I will polish the outer ring.
Shifting is pretty good with the ergos, although the f.mech clacks on the crank arm if you don't trim after a change onto the outer.

This would be possible if you found a (stronglight?) 94pcd 42t, there should be enough material to drill the 135 (?) Pcd holes to mount onto the record chainset, then mount a 32 onto the 94 holes.
