I would like to know how other roadies feel about the spoke reflectors that come on a new bike. My reflectors apparently impart some rather noticeable imbalance in my wheels, as indicated by up and down occilation of the frame when supporting the bike off the ground and spinning the tire. With slow rotation of the tire, off the ground, the reflector always rotates to the bottom of the wheel. Though not a factor at slower speeds, I have to believe this my yeild some undesireable drag or resistance of some sort at higher speeds (=>40kph). I would like to remove them if only for the appearance factor, however I do ride much after dusk during the Fall and Winter and the safety factor of the reflectors is a prudent consideration. Out of curiosity, what do ya'll think about this? I ride a Cannondale 600 with all 105, about 120 km a week.
