The Sachs branded ergo style levers pull the same amount of cable as the actual Campy ergo levers. Using a Campy 8spd or Sachs 8spd RD (which is what this example has), the Sachs levers will work fine with both an 8spd Campy and 8spd Shimano cluster. Something like 4.8mm vs 5mm spacing, not noticeable to most people. I think.

I would tone down the blue by swapping out the tires, saddle, and tape. But please leave the paint and decals be. Please.
