Gooseneck I have the same problem with my GT2 build because of running 24" rims, the posts are higher. Still pondering the brakes. Seems I saw the newer frames have 2 sets of posts?
I bought a disc set up for another build and it came with the thread on adapter. Just as a point of interest if one has a spare rear freewheel wheel you can swap the axle to a front, thread on the disc and have a front disc brake wheel. I may go back to 26" wheels just to make life easier on myself.
Not trying to jack the thread either but these discussions are fairly relevent to the topic.
