I'm about to enter the world of bicycles at the age of 54. I have not really ridden much since I was a kid other than taking turns on my kids bikes this last year. My two wheel experience has been on BMW motor cycles and did many "millenium" days on it. I'm now looking forward to doing a century with me as the motor. I have not yet chosen my bike. A big consideration for me is my troublesome neck. I cannot compress it by canting it back so I suppose I need to get set up with hybred or something similar. I will likely buy a Trek due to choosing the LBS first. I first thought I needed a 7300 or 7500 but after reading so much on this board questioning the ability of these to go long distance, I'm wondering if I need to look at a FX instead. I'll be most appreciative for all suggestions.
PS...I'm going to be involved in a ride of aprox. 500 miles in a 6 or 7 day span next July so I'm already training but I know my selection of the right bike is critical.
