I have: Shimano Ultegra clipless pedals New brake pads New tires (Schwalbe 28 mm) New handlebar tape Carbon bottle cage New chain (gold) With my previous rider I have covered approx. 9,500 km without any problems. I never fell over this distance, or had virtually no visible defects (scratches, stone chips). When you see me like this, you can't tell how old I am.
