bought a NOS 5speed chain for the new Peugeot
wider than the old one

i noticed on the old chain - every inner link was bulged [sp] out

I'm guessing a narrow 5/6/7 chain had been fitted
just wondered what you think.?

Hi John!
I've been fitting KMC Z7 6/12/18/21 speed chains to my vintage :smile: 5 speeder since I got him a couple of years ago, with no ill effects.

not regular enough cleaning and lubing .......Cheers Ed

You could have a worn freewheel.

Ed --- the bike is immaculate - signs of regular maintenance etc

Foss--- freewheel in good condition ..no probs running with old chain but the NOS chain is wider - and chattering

i am sure it's a compatibility prob with the wider NOS chain
it is a 14-28T 5speed Maillard [France]............tooth thickness is 2.22mm
which is prob the reason the narrow inner links are distorted --- see OP

my Shimano 20T removal socket doesn't fit
guess i need a Maillard tool.?

anyone with a Shimano 14-28 5speed freewheel...?
what's the tooth thickness..?

cheers...john

hi Pat
thanks --- who is the cog manufacturer..?
and can you measure the thickness of the teeth..?

cheers
Manufacturer is Shimano, pretty sure about this but will check again asp. Actually got 2 different wheelsets for that bike, with a 5 speed freewheel for each.
At first glance, your freewheel seems a bit smaller in diameter than mine.

Pat...........chain arrived today
cut to length and fitted with the supplied link ..........easy
chain runs sooooo smooth --and very quiet too
so THANKS for the tip

still have no idea why the one originally fitted had deformed inner links ...
made a chain whip from the ''too wide'' new NOS chain

new Bontrager saddle came too, so just waiting for brake/gear cables..............................:hyper:
