On display at the Europiano Congress in Dessau, Germany last month was a Steingraeber grand piano with experimental knuckles installed (see photo). These knuckles are actually small felt wheels that rotate on a pin. Holding the shank off of the repetition lever, you can spin the knuckle with your finger. The Steingraeber people say that this knuckle reduces the downweight by about 10 grams, but has no effect on the upweight. Initial reports are that children like the touch, but that pianists do not.
