When is a wheel out of true for minor wobbles? how far deviation before you will say 'Thats out of true'? I have a pair of relatively new hand builts - riding is fine and I don't notice anything but when checking the brake pads the other day, I did notice that the wheel isn't 100%. If its out of true - anyone know a good wheel builder in City, London? I am a stones throw from Spitalfields (Evans and CycleSurgery).
