Keirin Mirror Handlebar fit Silver Right Hand

I am used to using bike mirrors. I have three other bikes fitted with different rear view mirrors which I have done thousands of miles on. A good mirror needs to be easy to fit, vibration free and give a clear view of the road behind.This mirror is easy to fit and adjust and vibration free. The field of view though is too narrow to the extent that even when perfectly adjusted it shows vehicles well behind but has large blind spots either side.I removed it after one ride. For me a definite "don't buy."

Very good ordered to replace due to accidental damage
