Was just wondering what other people would choose between these two bikes. I ride a C59 now and was thinking the C60 is probably not much of an upgrade where the R5 is very light and has sharp handling. Rode both bikes was pretty impressed with the R5. The C60 liked as well who wouldn't. I have read reviews on the R5 and they seemed to be highly regarded as well as the C60. My thoughts R5: light, handles good, climbs well, stiff, looks are plain, lifetime warranty on frame, dislike bbright system. C60: handles very good, heavy, looks great, like bb system, resale value, nice long distance rider, comfortable, very durable and has an excellent track record for safety ( recalls). What are your thoughts?
