Great condition, it was used on a bike for about a year but I disassembled the bike, selling a few parts and keeping a few parts. A 120mm stem is a bit long for me and I don't see myself reusing it so this is one of the components getting sold. It weighs about 290g. Transition spacer is for an FSA ACR headset. Seems less likely but I also have a transition spacer for Enve if you wanted to put it on a Melee or Fray.
