My TDF derailer slightly lacks the needed total travel, even with axle and freewheel shimming to suit.

I don't have a suitably-geared French 5-speed freewheel here to experiment with, but am looking for a Suntour version as I was able to confirm it's adaptability with narrower spacers (albeit with it's English threading) without buying anything.

The total travel of my TDF derailer is just 21.6mm, but I haven't taken it apart. The bike it came with did have a 4-speed freewheel. Lastly, the "metric" threaded Suntour freewheels seem to appear on Ebay with regularity, but I lost a recent auction on a 14-24 4-speed French freewheel when the bidding went too high. I have yet to see or hear of a Shimano freewheel with metric threading, but am currently using the narrowed one with English threads.

Perhaps it would be easiest and best if I had just bought the expensive 4-speed, 14-24t French freewheel.

I'm looking for a Pro-Compe or Perfect Freewheel body or complete freewheel.

5 speed, French threaded.

I'll be building it up as a sort of Ultra-5, to work with my 1950's Simplex TDF derailer.

I prototyped the build tonight using an English-threaded body and easily got the width down to 23.6mm overall, the maximum that the plunger derailer will handle.

I previously built up a Shimano 5-speed body using 7-speed spacers with a re-machined body, and am still using that for now, but it's time to get the original rear hub back on there, hence my need for a french-thread freewheel.

I'll also be looking for an 18t (large-form, 4-spline) cog for it.
