1) Ive ridden steel bikes and i dont really notice the difference, but i didnt ride it for too long. The only reason i got the JR was because i liked the frame shape over the mark V. I nearly got an all black mark V but im happy i got the jamie roy. I like the white on black scheme. As for the fork. I dont really know what the benifits are of a CF fork.
Ive been riding around all day and i must say this thing is beautiful.
