I’m 6’4” and I have the XL with drops the 120 stem and inline seat post fits me perfectly. So if your going drops I’d suggest you go for the large with an equally long stem.
From the website: What size do I need?
Our frames are COMPACT geometry, meaning you need to knock 3cm off “conventional” frame sizes.. So for a Pompino, here’s our size guide.
* 57cm – XL – from 6? to 6?4”
* 54cm – L – from 5?9” to 6?1”
* 51cm – M from 5?5” to 5?10”
* 48cm – from 5?1” to 5?6”
Of course with them being compact, if you want a longer frame, you can go up a frame size without ruining yourself on the top tube.
