bike 1) lovely :- I love its looks, I also like the seatstay area but its hard to tell whats happening because of the gloss black paint.
bike 2) not my cup of tea, I never really liked the coust frame design, this is an uglier virsion
bike 3) less keen on this one, it kinda looks like what the terminator would ride, surly the more parts then the more there is to go wrong?
bike 4) this is more like it :( its got more traditional looks, not too keen on the dropouts though
Bike 5) Sorry, not keen on this at all! If the dictionary had pictures next to its words, that would be with Ugly.
I think Frame number one, with the carbon top tube of number 4, one piece bb/yolk and possibly the brake mounts of 3 (if it works well) would be a top frame!!!!
