Should have done it when the frame was yours Geo is 1075, 375, +25, 72, and from the single ride I've had on it so far - it's a bit nice! Coming from 1070, 380, +20, 72, it's easier to pop on the back wheel, easier for static ups to backwheel, and front wheel stuff is easier, will be able to give you a better idea once I ride it some more!
