how to find wheel brand
you need to know the width of the front fork at the axle, to know what width your new hub needs to be. Then you need the diameter of the wheel (mostly stated on the tire, 26" or 28" usually) and if you need a wheel with a braking surface on the rim of the wheel (if you have v-brakes: yes). If you have a disc brake in the front, you need a compatible hub for this. With those four things in mind you can go and look for a wheel :)
