A very expensive aftermarket updated front or back replacement brake rotor
A very well made updated replacement brake rotor, that may find its way onto another RD400, that a vintage rider friend of mine is slowly undertaking. I have had a local bikeshop fit on newer one piece brake rotars on to my own RD several years ago.They do last a very long time, so for just now this new floating brake rotor will probably wait here till, one of my RD rider friends finds a "need" to install it on one of their RDs. Being a very mature aged RDrider, means i mostly do essential short rides around my local community, especially in this very wet wintery cold weather thanx.
