Ok, so you're pretty tall.

195cm = 76.7" or about 6'5"
100kg = 220 lbs.

For classic frame dimensions, you're probably looking at somewhere around 60cm to 66cm.

You haven't listed a location, but I'd hunt for a used road bike or cyclocross bike (or bare frame) as close to what you're wanting (aluminum?), or steel if you wish for a horizontal top tube. You can build it up with your target component group. And, then see how you like it. Do a few adjustments as you go until it is comfortable.

Put a few hundred, or a few thousand miles on your sample bike.

You can adjust:Once you are completely happy, talk to your bike builder.
