Bike Fit & Sizing

Bike fit is a combination of science and personal opinion, perhaps more weighted toward personal opinion. Not only is each person shaped differently, but we all have different amounts of flexibility, fitness, and purposes for our bicycle. Some riders of the same height have long arms, long torsos, and some others will have arms like a t-rex. Some riders will use the same bike for racing that others will use to commute. To simplify a complicated subject: no one bike brand, model, or size will fit everyone. Even custom made frames are compromises based on a particular riding style or use. (The cyclocross race bike that fits one person may not be the same size or geometry he or she needs in a city or touring bike.)

Use Our Sizing Guide

We have developed our sizing chart using standover height to help the vast majority of riders get a great fit for our bikes. Standover height is the distance from the ground to the middle of the top tube of a bicycle. You’ll want 2-3cm (about an inch) between the top tube of a road bike (perhaps a little bit more above the top tube of a cross or mountain bike) and your true inseam.

Your true inseam isn’t the inseam measurement of your favorite pair of skinny jeans, it is the distance from the ground, barefoot, to the bottom of your pubic bone. The easiest way to get this measurement is to hold a book up next to your pubic bone while standing against a wall, then measure from the floor to the top of the book.

Visit a Bike Shop

Our strongest recommendation is to visit a bike shop. Any shop with good customer service should be happy to help you with at least the basics of bike fit for the type of bike and riding you want to do. Some shops may even charge a fee for a professional bike fit, which isn’t necessarily a bad thing.

For those of you who like to do a bit of Internet research, Sheldon Brown, the late bicycle guru, wrote a great article about bike sizing a few years ago. It’s still relevant today and worth reading:
