Toolbox: The Gears of Breathing

Better breathinig can significantly improve your ablity to improve both power and fatique resistance. The first step in mastering your breathing is to learn how to use your gears!

The Gears of Breathing

Breathing is one of the simplest tools we have to regulate effort, manage stress, and improve power delivery on the bike. Yet most riders default to whatever pattern feels natural in the moment, which often means shallow, inefficient breaths that do little to support performance. The goal of our breathing system is to give you three clear gears you can use to match your breath to your effort, stay relaxed, and manage carbon dioxide more effectively. Better breathing supports better riding.

Gear 1

In through the nose, out through the nose

This is your lowest gear. Nose to nose breathing promotes calm, steady ventilation. It slows the breath, filters incoming air, and keeps carbon dioxide levels stable so you stay relaxed and efficient. Gear 1 is ideal for easy endurance riding, warm ups, and any moment when you want to stay grounded. It is also your first tool for down regulation and reducing unnecessary tension.

Gear 2

Strong inhale through the nose, strong exhale out the mouth, Smell the roses, blow out the candles

This gear supports rising demand without losing control. The nasal inhale helps maintain rhythm and reduce over breathing. The purposeful mouth exhale improves carbon dioxide clearance and gives the diaphragm a clear movement pattern. Gear 2 works well during tempo, sweet spot, or any sustained effort where you need more ventilation but still want to stay composed.

Gear 3

Deep mouth inhale, strong mouth exhale

This is your highest gear. When intensity climbs and the workload demands rapid gas exchange, you shift to fuller ventilation. Mouth to mouth breathing allows you to move larger volumes of air quickly, helping you maintain oxygen delivery while clearing carbon dioxide at a faster rate. Gear 3 is appropriate for high intensity work, surges, and moments when you are pushing toward your limit.

Why these gears matter

Breathing is not only about getting oxygen in. It is equally about removing carbon dioxide. Elevated CO2 is one of the primary signals that increases discomfort, tension, and the sense of being overwhelmed during harder efforts. When you match the gear of your breathing to the gear of your riding, you regulate CO2 more smoothly and prevent unnecessary spikes that can drive panic, fatigue, or early shutdown.

The gears also reinforce a progression. Rather than jumping directly from calm nasal breathing to frantic mouth breathing, you move through steps that maintain control. This reduces over breathing, keeps the diaphragm engaged, and supports better focus. It also gives you a down regulation pathway after hard work. By gradually stepping back down through the gears, you can settle your system, reduce residual CO2, and restore a sense of calm more quickly.

Learning to use the gears takes practice, but it is a powerful skill. Start by becoming aware of your breathing during easy riding, then intentionally shift gears as intensity rises. With time this system becomes automatic and helps you stay relaxed, efficient, and in control when the work gets hard.
