Worst mirror in the world!
.. in relation to the Cateye BM-300G Race Mirror that I recommend.
Summat wrong there, Mick. I have just bought my third
Cateye this past week for an extra bike ! I have had no trouble at all fixing it rigid. I am talking on flat bars here, not drops. Very surprised to be honest
I can only state what happened with mine.
Actually, as a further experiment, I removed the the supplied screw and replaced it with an Allen bolt and a nut for the inside. Originally, the screw just screwed into the plastic boss and as you tightened it, the boss expanded the outer housing to grip the inside of the 'bars. I couldn't get it tight enough as the screwdriver was slipping and damaging the screw head I was trying so hard, so with the Allen bolt and inner nut in place, I could really swing off the tension.
It didn't hold the mirror tight enough even then - why? because the basic idea is awful. The whole gripping idea is reliant on the wedge of the boss gripping the inside of the 'bars AND the outer plate to hold the mirror ball+socket. The tighter you screw to get it to grip, the more the outer plate bends and gives. I could give Cateye the benefit of the doubt here - maybe my problem is that my old fashioned Cinelli 64 bars are the wrong gauge for it.
Poor design IMHO, but what do you expect for £6. It was ok at low speed, but as soon as the wind blew or I got over 15mph, the mirror would move.
Pay for the B+M mirror instead, far better.http://www.sjscycles.co.uk/busch-and-mu ... prod16565/
