I recently bought a DA headset that was missing the fork crown race. It's an older model that uses ball bearings, not cartridges.
Can I use a random (i.e. non DA) fork crown race with no ill effect, or do I have to track down a matching race? Will an Ultegra or 105 race work well with this headset?
as well, please pm me if you happen to have an extra DA crown race to trade.
