Developed as the company's flagship series, K Constantinople cymbals are crafted to emulate the handmade cymbals Zildjian produced in the early 20th Century while still in Turkey. Designed to develop a more complex character as they age, each cymbal is hand-hammered, producing unique attributes even between cymbals of the same size and model.

The Flat Ride was constructed with a depressed bell for a marked stick response with nominal wash.
