Bike fit starts with two numbers: stack and reach. Our full guide to stack and reach explains how to read a geometry chart and find your size, and credits the independent resources, including MyVeloFit, that informed it.
The short version
Stack controls how high your handlebars sit. Reach controls how far forward you are stretched. Together they place the front of the bike relative to your feet, which is most of what fit is.
Getting to your numbers
Measure your inside leg, then compare it against the published geometry for the model you are considering. A frame within about 15mm of your target stack is workable, since headset spacers and stem length adjust the rest.
Choosing between our models
Once you know your numbers, our guide to Vektori, Fluxi, Spektri and Halo helps you match a frame to how you actually ride.
