My 0.02
– SID Team 2007 is young enough to be equipped with quite decent motion control damping and old enough to still be dual air versus today’s solo. That means adjustability on par with or even better than most of the modern designs. One has to read the adjustment manual though 😉
– 32mm sid was quite stiff for xc. As a fork. Especially the 26″. As a system, the qr 9mm would show probably more flex, but that is not the matter of the fork’s age.
Anyway, I would not expect significant change for the better upgrading to a 2016 fork (note:I am talking about 80-100mm xc fork range!). Personally, I would trade my SID WC Brain 29’s stiffness for the adjustability of an old 2004 sid WC dual air I have on my other bike anytime.
But I am light&tiny (below 120lb).
