i am looking to get some luggage for my bike. been to all the shops and been looking online. found a few likely candidates. just cannot seem to decide between getting a tail bag or saddle bags. saw a decent size gearsack tailbag for around $130. also saw a rather simple saddlebags for $89. one of the things is that my bike any shocks on the side which would then rub against the saddlebags. is that going to be a serious problem? any suggestions?
