The rear brake can fail, posing a crash hazard.
Consumers should immediately stop using the recalled bicycles and framesets and contact their local bicycle dealer to schedule free installation of the repair kit. The repair kit includes a hydraulic brake hose/line, and a new frame insert for the rear brake hose and rear shift cable.
This recall involves Open Cycle-branded bicycles, models U.P. Ekar, UPPER Ekar, WIDE Ekar and MIND Ekar; and all Open Cycle framesets using a Campagnolo hydraulic rear disc brake. They were sold in matte black, blue, gray, orange or a custom color. Only bicycles and framesets with Campagnolo hydraulic brakes and hoses are included in this recall. The "OPEN" logo is located on the top of the downtube and the model name on the top of the top tube, near the seat tube.
