See photos (in replies - couldn’t upload in starting post): alloy Ritchey Zeta discs from around 2021. Rust problem at the valve opening, I could remove material by hand (while it is Summer here right now, so these wheels haven’t been wet for a while!). There’s also dirt/material inside the rim bed. Used in all weather conditions (commute), but always parked inside (dry and heated room). Regularly switched between tubed/tubeless, last months have been tubed.
Already contacted LBS - in the meantime, is this rideable still? Or put aside to be safe?
Anyone had the same experience?
