Very loud.
I recently built up a set of 24 / 28 Profile Elite Road hubs and could not believe how loud they are. In fact, they sound more like a BMX hub than a road hub. 6 pawls dig into 68 steps on the ratchet ring, making them the bane of your riding buddies’ existence.
Made in the USA, from hell hornets apparently…
