I have lost some ground clearance, But I originally had nine inches at the pedals lowest point and I think the frame is where I want it. What does that leave us to modify? The fork. That's where I think I can gain some clearance back. even though I won't need much for this urban curb hopper. As far as the look... A ridiculous long BMX, a squished 10 speed with 20" wheels.It's looking much better. I don't really know the look you are going for, have you considered moving the seat back and the BB forward? It looks like you are losing ground clearance on the pedals.
