Mavic open pro rim pitting

I recently purchased a new mavic open pro rim for a rear wheel rebuild, today whilst cleaning the bike I noticed one side of the rim (drive side) has dozens of tiny bubble like pits all the way around, as I said its only on one side which seemed odd so I removed the brake pads to check for debris - nothing!

The pads are new at the same time as the wheel build, aligned correctly. The bike is kept very clean and has only done 1300 miles since the new wheel.

Could this be a fault manufactured rim?

Should I be worried that it's going to fail?

    Could be the mfrs fault. Take it back to where you bought it and if no satisfaction contact Mavic.

    Rims are extruded, so unusual that you should only have fault on one side - have you tried polishing it e.g. Scotchbrite / fine steel wool?

    Yes I did that this afternoon, most of the bubbles have gone, i'll keep an eye on it for now. It would be a real pain to send back as I just bought a rim and had the LBS build it.

  • Rim was probably stored with one side facing the sunlight/air. :(

    Probably some localised surface corrosion / discolouration due to salty road spray on bare metal.
