Trolling around Paceline it appears the claim from Grant Peterson also mentioned his evidence of lack of fork flex included paint chipping off if forks did flex appreciably. Which is hilarious, would you be so kind as to share the article if you have it available? I looked in the index of Rivendell Readers and was not able to find anything.
But just to make sure this shakes out fair I will claim Dave Kirk as being in the curved camp as well as every French constructeur.
