Hi ALL, in my research for braking options (master & calipers) took me to the N3 site which has a lot of threads. One Co. that popped up for a Radial master cylinder was FRANDO out of Taiwan (not china). Very reasonable prices for Radial MCs but I couldn't find much info or reviews. Lo and behold I get my FASTBIKES mag today and inside is a review of the FRANDO Radial MC. Farmer Brod (Bruce-Editor Brother) has been racing a 675R with it and gave the FRANDO Radial MC a high rating. They run around $170.00 shipped and they are also sold thru VENHILL in England. Replacement parts & rebuild kits are available. I know they sell a 15mm Radial MC and that's what I plan on purchasing. Just my two cents but way cheaper then a RCS15.
