This is a 9-speed series pair of Shimano Ultegra  dual control levers, model ST-6510. These are 2/3 x 9 speed levers. They are  complete and fully functional. I just flushed and lubed them. Shifts are crisp and precise in both directions. The brake levers close and open smoothly. The rubber hoods are supple are good for many more miles. These levers show cosmetic wear. They are good, fully functional levers for your rider bike. I have uploaded large photos. Please take a look and ask if something is unclear. Thanks!
