spoke length and tension; Front and Rear DS and NDS for Peugeot triathlon 86'
Hello, I got my first broken spoke
in months since I got my bike and restored it
. Can you please help me with telling the spoke length and tension specifications, the hubs are Normandy luxe competition, with Maillard helicomatic freewheel and 36 spokes. gauge and nipples also if that is an useful piece of data when replacing broken spokes. If you need more description, please let me know. thanks.

I assume your spoke broke at the elbow. If so, all you need do is spin it out of the nipple, and measure it. Spokes are measured from the end to the inside of the bend, so you have exactly what you need.
If you unscrewed and discarded the nipple, you just learned the first rule of mechanical work --- never discard anything until you're absolutely sure you won't need it. The safest way is to never discard anything until 4 days after the repair is completed, checked, and road tested.
However you still have a bunch of spokes to measure, place a ruler along any spoke and measure from the elbow out to the end which you can gauge using your X-ray vision.
As for the tension, if the wheel was OK before the spoke broke, don't touch any adjacent spokes, and tension the replacement until the wheel is aligned. You can confirm that it's a close match to the rest of the wheel by spinning the wheel with your thumbnail pinging every spoke and co paring the pitches.

Or, remove another spoke from the same side of the same wheel, and take it to bike shop to measure and replace.
While you are replacing the broken spoke, you should check tension on the wheel. Maybe the spoke broke simply because it was old, but maybe not.

the advice above sounds good
but i have one slightly peripheral
huh
to espouse
this sounds like an odd combo
i wasnt aware that any company other than maillard
ever made a hub to fit helicomatic freewheels
i am sure someone will inform me of my ignorance
though

BTW- I vaguely remember that Maillard isn't the corporate name either, but it's been over 40 years since I did business with them so I'm not sure either way.
