Help with C-C sizing

I'm really confused about the whole C-C sizing for a bike that I'm going to order online (Mercier Kilo TT,
Save Up to 60% Off Fixie | Fixed Gear | Track Bicycle | Mercier Track Bikes | Singlespeed Bikes - Kilo Stripper). I used the fit calculator and it looks like I need either a 53cm(56C-T) or a 55cm(58C-T). To me it looks like I'm in between these sizes but I could be misunderstanding the whole fit guide. Which one would be a better choice for me? Thanks

My measurements:
Actual Inseam: 33 In
Trunk: 25 In
Forearm: 14.5 In
Arm: 26 In
Thigh: 24 In
Lower Leg: 22.5 In
Sternal Notch: 66 In
Total Height: 70 In

Eddy fit:

C-C to my knowledge means center to center , to find center to top you add the radius of the tube..



since you are wanting a bikes direct, no dealer, bike .. ask them . It's their business not mine ..



if you cannot buy a bike from past sizing knowledge of your own bikes

that may not be the place to get your bike.. and you should spend the money to get a bike you can test ride first.

.. and will be set up and ready to ride.

and have the Local shop help available after the sale..

The geometry chart for that bike indicates steep angles and real high bottom bracket. That is not exactly the type of bike that fit calculator was created for. Plus, I think you are hung up on seat tube measurements, which probably aren't really the primary issue.

I'm with fietsbob, this may not be a good way for you to go.
