FYI as the size of the Crust gets smaller, the head angle gets more "relaxed". My XS Bombora has 71 mm of mechanical trail-and Large has 65mm of mechanical trail. This is a rare case where the smallest size is perfect for me(thanks Matt and Cheech). It make me forget how my Cervelo RS feels and reminds me of how my 1993 Barracuda(Tange ultimate Superlight ovalized tubing hardtail(it was stolen) felt to ride. :) :) :)
