A bike is only truly custom when the frame is made specifically for the rider, for example having different measurements to fit the rider better than a generic production model. Another example is of a frame being altered by the manufacturer to suit the needs of the rider better, like for example having the stock geo altered.
Grips and stickers only personalize the persons bike, underneath it's still the same frame & components that anyone can buy.
entirely hand made frame, bike built from the fame up?
