Ok, going to give the 44.1 another try. Just picked up mattp's roller. Will do the bb spring conversion, but what about the hex? The front is already a hex but i could not find the size? Is it 12mm? On the 44 the hex goes on first and then the pin. Not sure if this will work with the hex conversion hubs. The rear is the same as the b4 so that will work and i can share wheels between cars. What about front hex? If the front hex conversion works what wheels do i use?

The steering rack looks different between the b4 and b44. i assume the avid rack will not fit the 44?
