What forks I need for old peugeot

[stupug]

I have a late 1980's Peugeot premiere. I had a lose headset but have narrowed the problem down to the threads on the forks having been threaded and chunks missing out of them.

I know it's a 1" steerer tube and I've measured the difference between the headset cups to be 112.5mm is that all the measurements I need to find the right sized forks?

You just need a set of forks with a 1" steerer - not that easy to find these days I'm afraid. Best looking on vintage forums for second hand ones. Or you could try & get the threads recut - you'll need to find a bike shop to do that for you

There is chunks missing from the tube so don't think it's worth rethreaded. I had it in a bike shop to get the stem removed a few months ago. They said it was very hard to get out etc. But I never removed the headset at the time and just now when I have I've found that it's threaded and chunks missing

Are the missing chunks randomly scattered or is it more like a flat running the length of the threads? If it's the latter, they're meant to be like that.

Any pics of the threads to show what the problem is?

i have these forks from a peugeot competition 2000. they fit your requirements i think measuring 112mm. you can have them just pay the postage and ill post them to you. the top tube has a ding in it and the bb is rusted in hard so the frames pretty useless but the forks are

good.

Wow! What a generous offer. Chapeau!

If for any reason it doesn't work out, you can buy forks like these from ebay. The only thing you need to make sure of is that the steerer tube is at least long enough. Cutting off any excess with a hacksaw is actually a lot easier than you might think.

^^^^^^^^+1
A tip for cutting down threaded forks is to put the top nut onto the thread below where you need to cut by about 2mm, you can then use it as a visual guide to keep the hacksaw straight and after you've cut removing the nut cleans up any burrs on the thread.
I normally guage where I need to cut by assembling the fork and headset (leaving off the top 'locknut') then marking it with the hacksaw, remove the fork and cut it in a vice, just remember If you cut off too much (cos you haven't left enough thread for the top/locknut) then you're kippered (or rather the fork is)

Is the steerer tube 1"? If so yes please and thank you

So he won't pass them on for free now. Has to go with the headset for a cost. Cheers.

If anyone else has any forks or knows of any, please let me know

 

[stupug]

I've had an idea. As the top part of the headset will tighten up until where the threads have been threaded I could put some spacers in so it would tighten fully. Would that work ok?

@2clepto @stupug I suggest you two chaps delete the last couple of posts and agree on £20. Even if they cost you a fiver more than you hoped, @stupug ,then it's a pretty sweet deal, I would say.

No need to fall out over it and besides, you'll likely pay more from eBay etc.

ps, I'm not on any commission, just don't want to see two guys who clearly have a common interest fall out.

Yes, provided the threads bite firmly.

Don't think it could get any worse than it is now. It is so loose
