Pitting on my Mavic rims

Hi All,

The rims on my Mavic Ksyrium rear wheel have developed what I can only describe as pitting. There's sporadic, small marks where the alloy breaking surface seems to have corroded and is rough to the touch.

The wheels have been kept clean and the front wheel isn't effected. The wheels are less than 12 months old.

I've tried giving the rim a good clean but these little flaws look like they'd need to be sanded/ground off. Mavic rim stone, perhaps?

Any recommendations on remedying this please?

    It's just surface corrosion due to the action of the brake pads abrading the surface and contact with liquid - if you polished them out they'd just appear after the next ride in the wet. Giving your bike a wash after each ride in the wet is a good thing - particularly in winter when they grit / salt the road. Remember, rims are sacraficial and wear is expected and don't stay new looking
