I think this is my first-ever first post - I normally "just" reply
to others. I am curious about why folks here like the keirin
frames and why the NJS parts are so popular.

I have followed keirin builders since the late '70s and also
own a custom Nagasawa road frame. Throughout the '80s and
early 90s, all of my frames were built with NJS approved
lugs, bb shells, and fork crowns. And for as long as I can recall,
NJS parts have been in Campagnolo catalogs and available for
sale (for at least the past 20-25 years).

What caused the current interest in keirin and NJS?
Are you guys riding track or following the circuit in Japan?

Just curious!
