Frame size
Hello everyone!
First of all I have to write that I hope my choice of forum category is correct (I am a new member of this site...). However my question is about frame sizes. I am going to buy a Trek 7.6fx but I am not sure about the size of the bike. I am going to purchase it on the Internet, which means that it's impossible to testride the bike. That's why I consulted wrenchscience.com to get my measurements, which are seen below. Below those numbers, there is a link to Trek's homepage and the geometry of the bike. Finally to my problem. I don't know how to decide what size the bike should be according to the wrenchscience.com result. I would appreciate some help to apply the results on the Trek chart. Thanks!

Hi Sven, and welcome to Bike Forums.
What you didn't provide is your measurements. How tall are you, and what is your leg length? By "leg length", I mean with you standing in bare feet on the floor, what is the distance from the floor to a snug fit into your crotch? The best way to measure this is by standing against a wall with your feet about 18 cm apart and tucking a book squarely against the wall on one side and snugly into your crotch on the other side. Measure the distance between the floor and the top edge of the book nested into your crotch.
