Apologies in advance if this is a silly question.
I'm just starting out doing DIY adjustments and I'm in the middle of replacing and tuning my brakes (just regular v-brakes). Anyhow, in the process, I was checking the wheels with my bike upside down and noticed that the front wheel tends to develop some momentum on its own after I stop it. I tried to find where the weight was coming from by balancing right where the wheel does not roll forward or backward on its own) and revealed the balance point was close to the center (drawing an imaginary line down) of the reflector on the spokes. This seems logical since this is added weight on the wheel.
On the rear wheel, the heaviest point seems to be the area of the valve stem , which is opposite the rear reflector. I don't know if this affects anything at all but I'm wondering if its important to have "balanced wheels" i.e. evenly distributed weight throughout the wheel or if this is insignificant considering the amount of weight added by the rider. Thanks for any input.
