I'd love to see one of these "etoiles" in action. As the spider on the Pro Vis attaches to the big chainring from the BB side, this can't be any kind of spacer/washer between the ring and the spider as that would only move the chainring closer to the crank arm. I must assume this gizmo allows the crank arm to attach to the outside of the big ring (away from the BB side) and that moving the ring from the outside to the inside of the spider is what gains you the clearance. As the inner rings attach only to the big chainring, they would be unaffected by the change. My only worry would be what the cranks look like with the rings bolted to the wrong of the spider.
Regarding cross applicablility, the TA has a unique attachment system so I don't see this working on a crank with a conventional spider like the 99, assuming I'm correct on how the gizmo works.

Mike Berry (Mariposa) at Bike Specialties in Toronto sells a space that increases the gap b/t the crank and the big ring on the TA Pro Vis triple chainsets. It may work on a Stronglight as well. Don't know. I'll order one for myself when I get my TA setup. Here is the link and an excerpt from his site--

Note. The 'Etoile' Up until now those wishing to use the TA Cyclo-touriste crankset with a modern front derailleur have found that the space between the outer ring and the crank arm has been inadequate. Older front derailleurs had a flat outer cage plate but all the new ones are shaped and require more space between crank and ring. Now we can offer the "etoile" which spaces the outer ring over about 4 mm which makes this classic crankset perfectly compatible with the latest front derailleurs. To include an etoile with either double or triple set add CAD$20.00 to the above prices.
Good luck! Peter Jourdain Whitewater, Wisconsin

you know the
Model 99 is a "low-Q" crankset with minimal clearance
between the crank
arm and chainring. So does anyone here have a good
recommendation for a
front derailleur. The ringset is 52-40-28.

You'll need to find an old Huret or Simplex. All
modern triple
derailleurs have shaped outer plates and will either
rub on the crank
or
on the chain.

On my Stronglight 49d with TA rings it is 5.5 mm (just checked with stack of feeler gauges); it was the same with TA on TA. That ain't much, and I think I measured 7 mm for a Stronglight 99 (several months ago, don't remember exact figure). So, Peter is giving good advice. I could not get either an early Shimano DuraAce or a SunTour Cyclone to set up cleanly. Much to my surprise, a homely Campy record is doing fine. But, I'd still rather find a pretty Stronglight 99 crankset for the Hetchins...
