I've discovered that I need a more aggressive riding position for almost any type of bike. The more stretched out I am the more comfortable I am on the bike. Also for me WSD for road bikes is totally useless. I am sort so that makes it even harder, but I have short legs with a longer torso/arms. I wanted a carbon road bike, which I have and love that bike (Felt F5). I have an entry level Trek mountain bike (aluminum) which is just fine, since I still have issues riding any bike anywhere other than on pavement of any kind. Also have an entry level cruiser type bike that is most likely what we'll be taking on vacations. Actually bought it specifically to take to Bristol for the NASCAR races. The farther away from the track you can park the cheaper it is to park and the easier it is to get out. However, who wants to walk 2 plus miles to and from the track. So enter buying a bike specifically for that. The other idea is we plan on eventually taking a vacation to Oakracoke Island (part of the Outer Banks in NC). It is much easier to get around that island on bike than with a car, so the hope is to take the bikes with us so once we get to were we are staying we can leave the car (well pick up truck) parked for the time we're there and use those bikes as transportation.
