Is that a carbon bike with pressfit BB or is it alu with screw-in?Well, i needed to tighten up the headset 1/8 turn but has come back after a few days and there was a slight roughness so new top bearing in first over the weekend and see what happens, but a new problem started with a more of a clunking click with every 10 past on drive side when hard pedalling but not out of the seat on a hill, really doing my head in.
