Idk about doing 80 anytime soon, I’m not just gonna “send it” on the first time out. I still have to dial everything in, and test it at the “bunny slope” over, and over, and over again until I’m used to my equipment and then I’ll be moving up to a bigger hill. I’m not too worried about steering geometry, it may be a little slow to turn, but some front brakes should help prevent under steer, and I have a trick up my sleeve that should prevent speed wobble. Sorry to say but an epic video may not happen soon. Maybe a 30 mph pass sooner or later to show that it works.The ultimate validation is the video you will take of yourself at 80mph coming down some hill. The photo of you on the bike hurt certain parts of my body. Beyond that I hope the frame geometry is right and you survive in good health to raise that daughter.
