Product conforms but not yet assembled. A small doubt however about the quality of the item to see how it lasts over time! (Translated review)

JDD bearings that fit perfectly on CBT Italia Necker frame. While the original CBT bearings are useless (4000 km), these seem good. Installation is obviously simple but adjusting the steering is just as simple. It is much easier to find the right adjustment for my steering with these bearings rather than the original ones (Translated review)

Restoration of a headset that was "indexed" on a BMC FS01, no mounting problems, replaces the original. Let's see how long it lasts over time. (Translated review)
