Holy post batman! ill try to answer all the questions.
Yes and no, the headtube joint will be reinforced with a large 10 AWG chromoly sheet gusset, but the Chromoly tubing I am using is so goddam tough that im not sure that the gusset is even needed. I did a mockup weld of the headtube and tested it to destruction. heres the details of the test:
A piece of the 1.5" thin wall chromoly (.035") fish-mouthed with a mill, welded 90* perpendicular to a piece of 1.5" thick wall chromoly (.125"). The piece of thick wall was placed over a piece of 1.125" chromoly solid rod, and a 10 foot long piece of heavy wall mild steel tubing was slid over the piece of thin wall tubing. A weight was placed on the end of the 10 foot piece of heavy wall, it held 475 pounds before failing. This was without a gusset or heat treatment.
Brakes wise, the gatorbrake is the baddest "Bike" brake I have seen, and it was really cheap. 80 bucks cheap. Its about half again larger than the 4 piston shimano brakes, and the pads are huge and cheap. The bike will use a much larger than available floating SS rotor.
The seat position Isn't final, im not sure if im using an XR50 seat or a real bike seat.
As for caster, or rake angle, I was tweaking and tuning on last years bike, trying angled headsets, different amounts of sag in the front and rear suspension different tire sizes etc... and have worked out a good performing headset angle that this frame will use.
Wheelsize is 24", large tires are available and its not as useless offroad as the 20"
hope that answers them all
