two grooves in wheel rim

Bicycles Asked on April 18, 2021

Schwinn midtown bicycle, when replacing brakes I see the wheel has many grooves as shown in picture. I do not remember how it was before. Is this condition normal for the wheel rim?

One Answer

These are wear indicators.

After years of braking, the surface of the rim will grind down to a point that these grooves will no longer be discernable. At that point, you should replace the rim.
