i also want to share my experience, bought a pair of Velosa wheels with OEM hubs, DT350 replica it seems, below some pictures.
the ratchet wheel was very bad, i had multiple occurrences of "jumps" over the teeth losing traction on the pedal and it's very dangerous in my opinion especially when climbing.
i replaced the ratchet with original DT swiss 54T and it's like reborn, luckily for me since i wouldn't like to swap the full hub honestly.
on the front wheel, the hub is ok when mounted in the fork, but it has some loose when unmounted.
BTW can you see in the picture the bearing sitting inside the XD body? should i also change bearing in your opinions?
thanks!
