For sale is my Shimano 105 12s Mechanical groupset! This was used for about one year on a road bike. Everything is in great shape with a couple of minor scuffs/signs of use, all of which are pictured. The cassette is an Ultegra 11-34, everything else is 105. Can include a Wheels MFG T47 bottom bracket if it makes sense for your build. Happy to ship anywhere in the lower 48, buyer covers shipping costs.
