Shimano 105 groupset, mechanical with hydraulic brakes. In good condition, with corresponding signs of wear. It has about 3000-4000 km, so it is not new. The right shifter has been replaced with an Ultegra one. The rubber hoods should be replaced. Everything works well. It is sold with a 34T cassette; the chain is almost new, as are the cassette and the bottom bracket. The calipers are also almost new, with brake pads at about 75-80%. Preferably sold as a set, but we can discuss selling parts separately.
