Converting a Zipp 950 Disc
I recently bought an old Zipp 950 disc with freewheel and track threading. Currently it has a hollow road, 126mm spaced axel. I emailed Zipp about getting the solid/track axel kit, but unfortunately, they no longer stock these kits. They can have me send the wheel, and then somehow outfit it with their new track hub. How this is possible with something already epoxied on there is another story... Needless to say, I don't want to spend another $350 on this retrofit.
How do I go about getting the same end result without their kit? Specifically, the parts needed and how to pull it off.
