I've been riding the THM bb (non-ceramic) and crank set up for a bit now. I've recently removed the chain to check out the noise from the BB. I seem to remember that a similar noise was there when I initially installed the crankset, but I chalked that up to "new" bearings and thought it would wear in and the noise would be reduced. Standard english threaded version of THM's BB in a Look 586 frame, installed with proper torque, has not backed out. Clavicula crankset was installed as per THM's instructions. BB was not faced.
Here's a video of the bearing noise:http://www.youtube.com/watch?v=DV5KlvRhXKQ&feature=plcp
You will have to turn up your sound to hear it properly.
My concern is that there is too much drag. What are your thoughts? Normal for THM bearings?
