Hi Sam, yes. I have a B&M 'cycle stor' on my B and my wife's B has a Cateye.
The former has a spigot which fits directly inside the bar end with an
expansion type fitting. It needs a small amount of 'shaving' on the socket
of the spigot in order to increase the degree of movement of the mirror's
mounting ball for a full rearward view. Bought at York Cycleworks, about a
tenner.
The Cateye is mounted on an arm which fixes at a right angle, once again
inside the handlebar end with an expansion type fitting. Gives a better view
behind but, because of the arm, is subject to vibration. Bought at Halfords,
again about a tenner.
Neither interfere with folding, the B&M is small and light and does not need
any consideration when folding. The Cateye has to be swivelled, it's a
friction joint so this is done by hand (ie.without tools) when folding so
that the mirror 'sits' behind the rear wheel out of harms way when the B is
folded.
Choice of two then, I prefer the B&M as the vibration factor on the Cateye
can blur the image given the amount of movement/bounce in the B handlebar
set-up!
My wife prefers the Cateye (aren't the ladies lovely if not contrary!) as
the image is larger and sturdier. Two minutes to fit either.
