I finally had a break in the weather to try all 6 combinations and here are my impressions. I weigh 185 and testing the KranK 90a on a analog Prototipo deck with a 7.5 degree wedge in front and a 7.5 degree de-wedge in back.
AB - Full range of the hangers so be careful to get used to the range regarding wheel bite and motor cable range. Definitely ridable after my initial shock. You could likely ride inside your house with this setup
AC - Also full range of the hangers but a bit more feel, feedback, and return to center.
AD - Sweet spot for me here, loose front with a rear that brings you back for more. Divey but you bounce back. High speed capable as well as great carvability.
BC - Another favorite that inspires high speed, quick hard turns with lots of “g’s”.
BD - Fast track, open mountain road and fast street riding when you want to keep up with or beat traffic.
CD - Sustained high speed runs and definitely still maneuverable but you need to work at it.
I will try BD and CD in KranK 87 next.
