anywhere to get *just the locknut* for French threaded headset?

I have a 1970's Peugeot PRN10E, and am planning to build the frame up with some newer parts, probably as a singlespeed or with an IGH hub, and sell some of the pretty Simplex/Mafac/Stronglight parts on eBay.
If you want to urge me to keep this beautiful vintage bike together, please direct it to this thread.

Here, I'm just asking about the headset locknut. When I got the bike, it was missing the headset locknut. Peugeot switched to British threading (on headsets and BB's) around 1980, but this thing is French. I tested it by threading a normal British-threaded headset locknut onto the fork, and it threaded on fine but felt loose. British threading is 25.4mm diameter whereas French is 25.0mm, which I think accounts for this.

Anyway, is there a good way to find a French-threaded locknut? Just the locknut? I don't really care to buy a new French-threaded headset for this bike, and figure there have to be some cheap steel locknuts floating around somewhere.

ran into the same problem when i wanted to put a campy headset on my moto to replace the stronglight brinelled one. trouble is, campy headsets with french thread are $150 to $200. but i found the two french threaded pieces on ebay for cheap (the seller lowered her price through negotiation) and bought an english super record set for the standard ebay price. i then sold the extra threaded pieces on craigslist. it works out if you're really patient.

edit: i also had to mill the moto's fork crown down to receive its new english race. but it was all worth it to save almost $100 on the cost of a french campy set.

I wonder how long it will take you to find the lock nut unless someone was smart enough to stash a few? I also see some on eBay, but not cheap.

I think it's eBay, parts bin, or someone on BF who happens to have a locknut sitting around, say from a headset whose bearing races got worn-in/out. A parts bin is probably only worthwhile if it's been kept very organized. Imagining sitting there screwing nut after nut onto a British vs. French-threaded fork...

I went into a co-op for a French headset and walked out with and entire UE 18 that they hadn't been able to sell. Maybe you will be so lucky.

I'm in need of one as well, if anyone has an extra. I just picked up a Gitane TDF that has the wrong locknut on it....

If it's for a Stronglight, I'm no help. But I have a pretty nice Nuovo Record French lock nut if it'll help someone. PM me.

uh, we should talk.




I have Stronglight headset spares also. Whatwolf has the OP covered so I can cover bibliobob. Ill hit the bins early tomorrow.

I still need a French Campag lock ring for a BB. The PZ-10 is sporting stronglight lockring and no-one noticed or may be I didn't photo it!! I think the latter is true.

I have a pair of steel french threaded locknuts stashed away but at this point I'm only "fairly" certain that they are french threaded. I don't have any french threaded forks to test them on. But also I kind of kept them around figuring one day I'd find a French bike to build up and the part might come in handy.

Here's one on ebay: https://compare.ebay.com/like/2512667...Types&var=sbar

But also you could just swap out the fork for an english threaded one; I'd be tempted to do that since all you want is a rider. Doesn't the OP's bike have a hi-tensile steel fork? A good quality fork replacement would be a good upgrade I think and maybe easier than finding a french threaded locknut (and certainly easier than replacing that headset down the road).

This bike is beautiful; I wish I had bought one of these when I worked in a Peugeot shop but it was too rich for my blood then. I'm pretty sure they sold for right around $1k for a full campy NR bike; not bad.
