Hey Brian! I just remedied this problem yesterday with the exact same set up by using this on the rim sidewalls: https://www.mavic.com/en-us/p/abrasive-rubber-oc0831
Although it says it "cleans" the side walls, the abrasive rubber actually helps give the surface more texture to grab onto. All credit to my friend who's an ace mechanic for having this thing handy. Instantly made the howling go away! - Drew On Wednesday, May 20, 2026 at 3:12:17 PM UTC-4 Brian Turner wrote: > Thanks for all the helpful advice, everyone.
