You are your own database. Only you know what will work for you.

First off, try out a 60mm stem and see how you like it after several thorough rides. The stem is too short for that bike, but it doesn't mean it won't work for you.

Stack, reach and effective top tube length are all very important for a correct frame fit, as a general starting point.

Take the E. top tube and Reach measurements for your trek, in the size you are riding. Find the drop and reach of the handlebars specced for your size.

ETT + 50MM stem + whatever the reach is for your handlebars would be = general starting point 1

Reach + 50mm stem + handlebar reach = starting point 2

Stack is slightly more complicated because not all bikes have an uncut steerer tube with a generous helping of spacers mounted underneath. Y

frames stack height, plus however many spacers you're running underneath, minus the drop of your handlebars (assuming the bars don't have too much of a drop for you) would conclude as a general reference for your frame fit, assuming you find that 50mm stem comfortable.

To get an idea of how your stem choice will affect handlebar reach. There are comfort oriented drop bar bikes out there, Im sure. If you want a bike with a neutral hand positioning, you can always buy a good fitting flat bar bike and change the handlebars to the Soma Moustache 2...

Starting point for you would be a hybrid bike such as a Trek FX or similar, which places you into a neutral riding position. Ending point would be something designed for a upright riding position, such as perhaps a Trek Verve .
