Some high-end Vs have a parallelogram linkage to keep the pad parallel to the rim as it travels.
Anyone else notice what those cheap b*st*rds at Shimano have been doing over the years with their V-brakes?
I have a set of LX V-brakes with the parallelogram linkage, and also a set of XT V-brakes which also have it.
Both sets were purchased in the late '90's.
Today you can only get that feature at the XTR level.
XT & LX have both gone back to the cheap one-piece design.
I regarded the parallelogram linkage as the biggest advantage over canti's.
And for the record, the XT V-brakes are on a bike that has fenders AND rack with no interference from either.
