Seat clamp and headset adjuster?
Vittoria Diamante Pro Lights are lighter, cheaper and harder wearing than Open Corsa CX, an under-appreciated tyre for the weight weenie on a budget. Rolling resistance in the AFM tests is 13.5 vs. 12.3 for the Open Corsa, but still better than either Conti GP4000S or Schwalbe Ultremo.
