I've "heard" noises that may be similar to what you're saying. Can't remember if it was going down hill or not. I haven't been out west since January. But I do remember I kept riding and Pockets kept rolling on. Hopefully just a rock in the brake pads.Sounds like gears grinding but shifts fine runs great except for slow down hill on brakes.when I go down hill slow with out brake it’s fine 🤷♂️
Mine has done the same. Usually after it has been sitting undriven for a while.P-5 started making noise going slowly down hill when using the brakes,but it’s not a brake sounds like gear noise.shifts fine otherwise no problem any ideas.
