Might help to confirm if you can provide model name, size of bike and your height and cycling inseam.
This is a 2015 Scott Speedster 20, size medium (54). I'm 5'11. Cycling inseam is unknown. The LBS said the Scott bikes tend to run a touch bigger than other bikes, so when we were between the 56 and the 54 he suggested the 54.
