Not to get off topic but,
one of the reasons I chose the Stronglight 99,
was because the rings were compatible with the
SR Apex I used to tripleize my Super Mirage, in the photos above.

Thinking I could swap, and mix rings back and forth to get the desired combos,
that fit my riding.

But I'm sad to say that, that bike was stolen last month,
so that's not a option anymore.
