So was a different cleat required for Arc pedals than for the ones that seansmiller posted?

I would have thought that before any KEO or SPD/SPD-R/SPD-SL pedals came out, that all of the plastic LOOK and Shimano cleats were the same, or at least were compatible/interchangeable.

But I am also recalling one pair of the older pedals that I had, which would not easily un-clip as it should, using newer ARC cleats most likely.

[MENTION=46029]fender1[/MENTION] is right. The straightforward thing is to tap the cranks. [MENTION=185430]dddd[/MENTION], it is a rock solid solution.

All the other talk is conceptual. It's not practical, and it's not even æsthetic.

Moi.

Thanks to all that chimed in on this. Found out what I wanted to know...French thread clipless is a rare bird. I agree the sensable thing to to do is tap the crank....who's going to know...it's really a mind game.

Alternate ideas came to me as a result of everyone's input... 1) look at the shoe.. Can I take a contemporary shoe and mount an old school cleat to it and use an old school (and use the French threaded pedal that I already own)

2) how about taking a die to a standard clipless pedal and making it french?

When it's all said and done it's only a bike for god's sake. What makes it fun is there are multiple solutions to the puzzle. It all comes down to what fits your personal aesthetic (and circumstances).

Enough talk...bolt something on and go ride!

Yeah, if it's look/3 hole drilled.

LOL, I don't see why not, other than the risk of cutting them crooked. That'll show 'em. The die might cost more than some used Looks from France though...

BTW, you cannot use a french pedal in a 9/16 tapped hole. Don't even try.
