The Phil's rack is 1/4 inch aluminum BOLTED to the aluminum grab bars, that are BOLTED to the aluminum rear sub-frame, that is BOLTED to the aluminum main-frame. What plastic-resin "whatever" are you talking about? The seat sits on the ALUMINUM sub-frame. There are NO steel components in the C14 frame other than fasteners.......Hello?
Like I said (no insult intended..HELLO?) I don't think you've analyzed it enough.
The main frame
is Aluminum or
ALUMINUM if you prefer, but the sub frame that the seat sits on is..(
steel)...well don't take my word for it...take your seat off and get a magnet and analyze. I don't know what the composition of the grab bars are (thus the use of the term plastic-resin-whatever), I was hoping it was
plastic encased carbon fiber or maybe at least some kind of fiber reinforced plastic. Not knowing I opted for the Givi rack and support bars. A secondary consideration was the electrical connection for the top case brake lights was easier using the Givi.
I think Phil's rack is great from what I read, but the Givi rack support (in addition to being ugly) is steel and it is BOLTED to steel. Either one is an excellent replacement for the factory rack. Each person should analyze how they are going to use the rack and the appearance of same to make their decision. (soap box warning

) I don't believe the terms "no-brainer" or "over-analyze" should be used quite as often as I hear and read them day to day.
