The proper size bike is key to comfort, performance, and safety. The world's best bike, if the wrong size for you, won't make you a better rider.  Our bike sizing guide is meant to give some general direction as to the best size to fit you based on your height. This is just one variable in a very complex system between rider and bike so keep in mind that rider proportions, fitness levels, and other aspects particular to the individual cyclist has a big impact on how you'll feel and perform on your new bike.

Our size guidelines are not a substitute for a professional bike fit. If you have size questions, please don't hesitate to visit your local qualified bike fitter or reach out to us.
