Hi there,

I need some help. I'm putting together a bike using old and new parts. I'd like to get the following crank:


To put on a 1982 Peugeot frame I'm getting repainted. What I don't know is:

-What kind of Bottom braket do I need for this to work?
-I'm getting a Sram Automatix Hub in the back, will I have problems with this crank, having 44 teeth - linking the two together with a chain?

Sorry if this sounds too simple...

Also, I need advise. I have the possibility of getting a a Titan Luxe Stem; this one:

and then adding Nitto Dropbars - or I could get Livery Adjustable Stem which is a new product, so not vintage, but which I like because it's adjustable and looks nice too.

What would you all do?

Also, this Titan Stem seems to be 27mm ... my frame I believe used a 25mm (or so) stem. Can I still use this 27mm Stem somehow?

While cool looking as hell the cotter pin Lions head crank just isn't right for an 82 bike. It could maybe be made to work if you got vintage French BB with cotter pined spindel.

Eventhough I'm getting it repainted and adding eveything else (Brooks saddle, Titan Stem (perhaps), dropbars etc...) Does it look too old? At least from what you're saying, it's possible to use it?

generally speaking, you want to upgrade components, not downgrade them, regardless of how interesting their appearance might seem. i like the cottered lion crank too, but it seems like a mistake for an 80's bike. and have you held the crank in your hands? probably heavy as hell. i like the stem and bars you posted. if the stem diameter fits the steerer, you're set. take a look at similar peugeots, and i'm sure you'll find a crankset that fits the bike and is still attractive. drillium is always an option on chainrings. as far as the lion crank goes, buy it and mount it on the kitchen wall. that too would look great.

Yes, you CAN use one of those cranksets, if you can find one. Ebay will probably be your best bet. However I agree with the others, that crankset and a matching cottered bottom bracket will be very heavy and look very out of place on an 80's bike. The same for that steel stem--and you might not be able to use that--maybe you could shim it. If you really like that style, maybe you should look for a bike from the 50's or so?

Check your bb threading on that Peugeot. 1982 was near the time of the transition from french to swiss, to eventually, the british standard.

Welcome to the forum.

Welcome, and please show some pictures of the bike when you get it together.

I like the suggestion of you looking for a frame to fit the componant choices you are making. You seem to like that era of styling and it won't look right or work right with a newer frame. You would probably be better off selling your curent project frame and getting one that is older (50's-60's) Something with 120mm rear spacing and built for cottered cranks, etc...will make your build much easier

Also that chainring is super worn, check out the sharktooth teeth.

If you like the crankset, use it. It's your bike. YOU get to choose the components. You do need a bottom bracket with a cottered spindle as others have mentioned.
The stem is a problem with the larger diameter than the one it is replacing. The PX-10 I have takes a smaller diameter too. One option that may work is a replacement fork that isn't French. That will probably mean a new headset also. Maybe someone that knows for sure can chime in. It's starting to sound pretty expensive by now. It may be a lot cheaper to learn to love the original stem.

re: french steerer tubes... my 75/76 moto g.r. steerer is french threaded but accepts a standard diameter quill stem (22.2mm). did peugeots mix french and iso standards in this way?

No for the most part vintage French bikes are metric meaning even metric 22.0 stems 26.0 seat post are almost typical. Moto's where an exception in they started out sourcing and using deferent size components around 75.

Another welcome to the forums.

While I appreciate what you seem to want to do,
I sense you lack the mechanical sophistication to
pull it off.

Find a local bicycle mechanical adviser who wrenches
in French. He or she will be worth the effort you put
into the hunt.
