The Shimano BR-R9170-R is the rear calliper from the Dura-Ace hydraulic disc brake range. It is supplied as the rear unit on its own.
Being hydraulic, it runs on fluid rather than a brake cable. Order it as a straight replacement for a damaged calliper, or as the rear half of a Dura-Ace disc build.
