First, this stuff defines proprietary.
Probably why it didn't sell in the day.
That and of course the fact that K controllers
said no-go as it made for an unfair advantage.
At least that's what I've been told over the years.
Second, this is for French bike.
B/B cups are not marked NJS, nor should it be as I recall.
The BC date codes show it is correct.
Well we all know of course that this is the preferred traffic gear.
Again, Way COOL.
I will state that I currently run 3 bikes with 10 pitch.
No snotty remarks about fixed brakeless on the street please!!!!!
This stuff is by far the most bullet proof drive chain I have used on the streets for the last 25 years.
My current full time user drive train has at least 7000 miles put on it in the last 2 years.
Couldn't even be thru half its life yet.
Sure hope the seller appreciates this ad
Make him an offer.
Now let's think of way cool French track bikes to put it on.
Thanks for reading.
