I have a 60mm carbon clincher front wheel with a Novatec SB271 hub that makes a weird almost grinding noise when turning or side loading the wheel at speed. The bearing is totally silent when I spin the wheel just holding the wheel off the ground and there is no side to side play. When I sprint or turn the wheel sharply at speed, it makes a grinding or rubbing noise. The brakes are not dragging and there is nothing else close to rubbing on the wheel.
Any ideas ? Is it the bearing ?
Turns out it was valve rattle. I used non-threaded valves and they were rattling. As soon as I wrapped the stems with thin tape they stopped making noise...who knew...
