French Threaded Block Pedals, What Are My Options?

Gang, my Peugeot UE 18 mixte has become my go-to bike yet the pedals are slightly too narrow. I do not want to use toe clips therefore I want to replace them with "block pedals" (is that what we call them?). I see Velo and a few other companies are carrying the Atom French threaded road pedals (that use clips) but I have yet to find any "block pedals" that are French threaded.

Do I have any options or am I doomed to Ebay and the likes? Thanks

Chris

Chris when you say 'block pedals' do you mean just a two-sided platform or 'rattrap' pedal? The Atom pedals from VO are smallish, but are definitely a platform-style pedal. There is a regular eBay seller from Nancy, France who regularly lists a wide variety of vintage French components--including Lyotard platform pedals in French thread at reasonable BIN prices. You've definitely got your work cut out for you and patience is the key. Good Luck.

Sorry to be unclear :-) This (from our friends at Velo Orange) is what I have in mind:



What do we call these? Block? Platform?

It's trivial to re-tap metric crank arms to take English (9/16" x 20tpi) pedals. That would be your best bet for using block type pedals. VO doesn't specify the threading on their pedals so be sure to check that they are not 1/2" x 20tpi before you order them.

I'm not sure you'll find rubber block pedals in French thread (14x1.25) even on eBay. It may be possible to have your steel cranks tapped out to English (9/16x20), but I've only done this with aluminum cranks and do not know if this is possible with steel.

My guess is that those are 1/2" threads. They should know enough to specify the threading.

Are you referring to the MKS pedals? I'll bet they're 9/16.

FYI - the photo shown from Velo O are NOT French threaded. But they represent what I'm looking, if only French threaded.

You might be able to find a set on the French ebay but there probably isn't much demand for these so there probably aren't many being sold. One other long-shot option would be to find some pedal bodies that fit your current spindles.

The easiest route may be to just replace the crankset, BB spindle and pedals as a set.

Here are those same MKS 3000 pedals on Benscycle.com ($5 less than V-O, too). They say 9/16".

As stated above, re-tapping the crank is trivial.

And it's your most economical choice, in both money and time.

Wait, I'm the one who found out they're 9/16", so I'll take the TA ring--48t, please!

Too late. I already know they're 9/16". What BCD T.A. ring do you need?

While the auction text doesn't specifically cite thread dimensions, these lovely old NOS Lyotard platforms are most likely French thread.

I think I might have earned the C&V Dork of the Week award. According to Sheldon only REALLY older French bikes have French threaded pedals and according to this graphic from the retro peugeot site mine (rat trap) are English threaded.



I'll test this theory tonight when I see if a pair of MKS pedals fit.

Lyotard are my favorite pedals. The bearings are not as precise as the high end stuff like Campy, but it's every bit as durable. And they're comfortable. I can't stand quill pedals, because my feet are super wide.

My favorites are TAs with the quills trimmed off.

If I needed two left French-threaded pedals I'd be all over those.
