I'm trying to get a bombproof headset for my tandem. The extra loading means that they tend to have nasty, short lives.
The problem is that it's threaded, and decent threaded ones are gettign harder to find or pricey NOS.
Is there any reason why I cannot use the lower bearing and crown race off a threadless system with the existing (and lightly worn) threaded top race / cap assembly? Of course the stack height needs to be similar to get it all to fit together.
I can't see a reason why there would be a problem, just wanting some advice...thanks.
