I am looking for an online calculator/visualizer to compare the effects of different wheel sizes and fork lengths. I have used one in the past in which you could enter the geometry of a certain frame and fork combo and compare it by changing variables such as a different fork length, headset angle adjustment, wheel size, etc. I can't remember what it is called so if anyone knows what I am talking about or can give me a link to it that would be greatly appreciated.
That https://99spokes.com/ site is for comparing bikes, not about calculating effects of geometry changes. I've seen a few bikes with inaccurate geo numbers on it as well.
