If you are looking for a well-made generic 12-1/2" x 2-3/4" front wheel assembly, then we have just what you need. This is dimensionally very similar to our Razor MX350 Front Wheel Assembly, and might work as a usable replacement.
Of note is the three 3/16" threaded holes on one side of the hub for mounting a brake disc.
Includes the 12-1/2" x 2-3/4" tire and tube, rim, and axle.
