The top of it was solid metal but where you hooked on the derailleur hanger it split in two and the first time it broke on me the entire thing broke at once. The second time I had a bit of a heads up as one side of it broke and the other kept in tact. I had to wait and continue riding the bike for over a month while waiting for the new hanger to arrive as everybody including Wheels Manufacturing(the distributor) were out of stock. I've sit with a wheel that didn't want to stay attached to the bike a couple of times now. The first time was on a descent when it occurred. Boy was that a shock. I had never heard of a hanger breaking before. Made for a nice walk home.
