French thread vintage pedals

Hello all,

I do not want to re-tap my stronglight crankset and was wondering if there was a hidden spot somewhere on the internet that I can acquire clipless pedals with french thread.

Thanks

I suspect that they may not exist owing to the timing.

It's probably close, and I leave it to others to confirm or challenge, but if the advent of clipless was after the adoption of ISO standards for pedals, there's a decent chance that nobody bothered to make them for pre ISO bikes.

I have never heard of or seen any. The pedal threads (and freewheel threads) on French bikes generally started to migrate to ISO even as BB and headset threading remained French for a few years...

Look did make first generation pedals in French thread. You can find them on ebay france if your are patient. I considered buying some.

...if you think for a moment about your problem, you'll see that for stuff that is difficult or impossible to rethread, companies like Velo Orange make and sell French threaded after market parts like headsets and BB's. There's no market for French threaded clipless pedals because it's so easy to simply rethread the cranks...takes maybe ten or fifteen minutes.

If they exist, I've not seen them, and I've shopped for bike stuff on Amazon France and direct from some of the larger online shops there for stuff like Stronglight chainrings.

You can look yourself using google translate.

If I knew where to buy them, I would not have altered the Stronglight 49d on my Atala and the Stronglight 93 on my PX10. For what it is worth, I have been trying to find SPD with the French thread and finally gave up the search.

The only clipless I have seen in French thread were the white first generation Look pedals. It took about a month of searching on ebay France, then I decided I don't really like Looks as much as SPD, so I just kept the stock pedals.

French thread Looks are not going to be easy to find, but they do exist, at least in small numbers. It would probably be helpful to speak French or know someone that does, as I have certainly never seen them in North America.

I can only remember seeing Look clipless pedals in french 14×125 threading only once at eBay......so they do exist but they are quite rare.
That's why I am always on the lookout for 9/16 threaded Stronglight cranksets (which are getting harder and harder to find) , as I use modern Look Keo pedals on most of my French bikes, but do use period clipped ones on a couple. Using French C&V cranks with 9/16 pedal threading just gives me the most flexibility, while not resorting in to retreating the pedal hole and keeping the cranks original.....

First generation Look pedals are getting old and they were not that great. Everything loosened up fairly quickly. As soon as you find them (if you can) you'll be looking for another set. You'll need a supply of early cleats as well.

Other than absolute purity the reason to keep 14x1.25 threading is when you want some specific model of Lyotard pedal it just hurts to see that you could have all you want for cheap if you still had original threading but you need ransom money or great luck to get the same part in 9/16x20. If you are fully switched to clipless just tap the crank. The threads are very similar, the original threading pilots the tap perfectly every time. Not much metal is removed and it will cut clean.

A French thread retapped to ISO will be identical in every respect to one originally tapped ISO at the factory.

It's an easy job with very little potential for error unless you try. The tap will naturally pick up the lead of the old thread and follow it to the end. the minuscule difference in pitch, 0.49" vs 0.50" won't make any difference at all, since the accumulated error falls within the metal shaved off.

So, as pointed out, dicounting the desire to be period correct, or use a French thread pedal, there's no reason not to retap, freeing you to skip the search for a hard to get not-so-good 1st generation pedal.

look pedals

I have several pairs of Look pedals marked G and D instead of of R and L. If you're interested I can see if they won't thread into Campy or Dura Ace.

If they have French threads, they'll thread into 9/16" cranks, just be sloppy.
