Thanks for the kind replies...
It looks faster than I am...
I still have the original XTR-Canti-brakes, but there are no matching levers.
And yes: It's not ridden fo a long time - it was cleaned and was a piece of design in our house...
But now my wife asked, if it can be removed :cry:
And, honestly, I am thinking of buying another bike, so one has to leave...
