Most EVELO models are available in one frame size per model, with some models being smaller frames down to 15” and others going up to 17.5”.
Your height and saddle height are the most important numbers to focus on. Taking a measurement on your current bike from the top of the saddle straight to the ground is a great way to compare your bike, with the different models we have available.
