Logic would lead me to assume those with the Alpha Q forks have a longer head tube at the bottom to compensate for their shorter forks.
I seem to remember TandemRacer fitted a HT spacer at the bottom when he ran the Alpha on their Lightspeed.
But that's really a tangent off the original dilemma.
Anyway, regarding my comparison of my Santana to a Co-motion (w/ Wound-Up). My purpose for comparison isn't to say that they will feel all that similar, but more so to say that switching to a 45mm rake fork with a similar A-to-C length will not make the specs fall outside of generally accepted values.
