If you want a rider get a rider.
This is a unique Klein, with a lot of the story of cycling in it. Go and run it with modern stuff so you can go and ride it, if it is the only bike you have.
Or respect that it exists in a point in time that represents a phase in the evolution of cycling.
You have just acquired a unique frame. Make it no more than any bike that Evans could sell you, or respect it's heritage.
Your call.
