You are looking at a Shimano Dura Ace 7400/7402 group. It is the 8-speed STI version of the group. Everything is in good mechanically working condition and it is in great condition too! The following are included:
FC-7402 172.5 mm crankset
FD-7403 front derailleur
RD-7402 rear derailleur
BR-7403 brake set
ST-7400 STI Shifters
This would be a great set for a vintage road build of any kind.
Feel free to contact me if you have any questions at all. Thanks!
