The 60 millimeters that change a bike's whole personality.
Monsoon Cycles, Colorado Springs · Updated August 21, 2026
Chainstay length is the distance from the bottom bracket to the rear axle, and across our presets it spans just 398mm (1980 Criterium Special) to 460mm (Expedition Loaded Tourer). That 62mm gap is most of the personality difference between a bike that snaps through corners and one that tracks straight while loaded.
Short stays put the rear wheel under your hips. The bike accelerates like it is eager, changes lines mid-corner, and rewards an out-of-the-saddle rider. Costs: less heel and tire clearance, harsher over bumps, and with panniers it gets nervous.
Long stays put the wheel behind you. Stability loaded, comfort over distance, room for fat tires and fenders and heels against panniers. Cost: it will not snap anywhere; you steer it like a good truck.
The middle (about 415 to 430mm) is where all-road and gravel bikes live on purpose, including our Audax Fast Tourer.
