Shimano Dura Ace 7800 groupset. In good used condition - some marks and scratches showing the groupset has been used as intended, but still in perfect working order, just removed from a bike in regular use. Hard to describe but still has that classic Dura Ace shifting and braking action that is right up there with any modern groupset. Chainset is 175mm arms, 53/39 chainrings Cassette is Ultegra CS-6700 11-25 Chain is Ultegra CN-6600
