I just bought a 1984 Schwinn Voyageur. It is a touring bike but looking it made me think that is probably the closest thing to a CX bike that you can get without buying a CX bike.
I am ignorant about CX bikes so let me know what I am missing.
The Voyageur has canti brakes like a CX bike.
It has a nice lightweight lugged steel frame so it should be both durable and provide some spring when the course gets rough.
It has a more relaxed geometry like a CX bike because it was built for touring.
So what about it other than the drop tube shifters which can be upgraded would prevent it from being used as a CX bike?
I am not going to turn my gorgeous Voyageur into a CX bike but the idea remains, why couldn't it be done with good results? I am thinking if I wanted to build a CX bike, I would use a touring bike as a base. Is that sound thinking or am I missing something?
