Hi,
Since I've owned this bike, I've had problems with the rear brake. It repeatedly starts vibrating intensely – so much so that the vibrations are clearly noticeable throughout the frame, all the way to the handlebars.I've already tried different brake pads and rotors, unfortunately without success. The vibrations and the associated noises continue to occur regularly. I've owned many mountain bikes, but I've never encountered a problem like this before.
I took a closer look at the brake mount. I noticed (see photos) that the carbon part and the metal threaded part aren't flush. As a result, the +23 brake adapter has a very small contact area, which likely reduces its stability and contributes to the vibrations.For comparison, I checked other bikes, including my Santa Cruz Hightower. On that bike, the carbon part and the metal threaded part are perfectly flush, giving the brake adapter a significantly larger contact area and preventing comparable vibrations.
Does anyone have photos of this area on their bike so I can compare mine? Is the condition of my bike normal, or is it actually a manufacturing defect?
