That race face diabolus d2 stem I have has got to have the worst interface of any stem that I have ever owned, all it does is creek and moan and it's a chore to put on and to uninstal. Took it off after my ride because I was getting fed up with the creaking and put the Gravity Lite Stem back on and it's dead quiet now. Worst piece of junk that I have ever owned.
