I'm thinking about tweaking the angles on my Cruiser frame. The front triangle is done, now it's just a matter of the chainstays. I'm hoping for a Head angle of 72.5, with a bottom bracket height 12 inchs or above. It's amazing how much 1/4" inch of bottom bracket height can change the geometry of a bike. A 1/4" adjust the head angle a little over 1/2 a degree. It's something to think about when buying tires, since you an buy 24" x 1.5, 1.75, 1.85, 1.95, 2.0 and 2.125 and people like to mix them up.
