How to choose the right frame size
Most riders start with a height chart, and that’s the right first move — but it only gets you to a range, not a size. Two riders at the same height can need different frames depending on torso length, arm reach and how they actually plan to ride.
Start with the chart, not the guess
Start with the Size & fit information for the specific model you are considering. Frame geometry changes between a road bike and an urban commuter, so the same height can lead to a different size across our range. Compare reach and stack alongside the size label: “medium” is not a universal measurement.
If your height sits right on the line between two sizes, consider your proportions, the intended riding position and the adjustment range of each frame. Sizing down or up is not a universal rule. A test ride or a conversation with a fitter is more useful than choosing by the letter on the frame alone.
The best-fitting bike is the one you forget you’re sitting on. Get the frame size right and everything else — saddle height, reach, bar width — falls into place much faster.
Three measurements worth taking
If you want to go beyond the height chart, three numbers give your fitter useful context:
- Inseam — measure barefoot from the floor to the crotch using a level reference.
- Torso length — note the distance from the base of the neck to the hip crease.
- Arm reach — measure from shoulder to wrist with the arm extended.
None of these override the size chart on their own, but together they help explain many of the “I’m between two sizes” situations. Take each measurement twice and use the same method. If possible, also describe what feels comfortable or uncomfortable on your current bike.
Still unsure? Ask before you buy
A frame swap after delivery is more friction than a five-minute message before checkout. If your measurements put you between two sizes, our team would rather help you decide now. Send your height, inseam, the model you are considering and a short description of your usual rides. We can help you compare the available information and identify what to check on a test ride.
