Gravel cycling demands a unique balance of speed, endurance, and technical capability. One often overlooked but critical factor in optimizing gravel bike performance is crank length. For expert riders, selecting the ideal crank length can dramatically impact pedaling efficiency, power transfer, and bike handling over mixed terrain.
Shorter crank arms — typically 165–170 mm — have gained popularity in gravel racing and ultra-distance events. They allow for a higher, smoother cadence, reduce knee strain, and improve pedal clearance on technical trails or rocky sections.
This added ground clearance minimizes pedal strikes and increases rider confidence when navigating uneven, unpredictable surfaces.
Longer crank arms — 172.5–175 mm — offer greater leverage, beneficial on steep climbs and in situations where raw torque is prioritized over cadence. However, they can lead to a slightly lower cadence and increase the risk of pedal strikes in off-road conditions.
The choice often depends on rider physiology, terrain profile, and race strategy.
QO BIKE’s carbon cranksets are available in multiple crank lengths, allowing gravel cyclists to fine-tune their setup for optimal performance. Designed for high torque resistance and lightweight control, these cranksets deliver immediate, precise power transfer while minimizing flex and fatigue over long, demanding rides.
For serious gravel cyclists, crank length selection is more than personal preference — it’s a strategic decision. Choosing the right crank length improves efficiency, control, and comfort over diverse terrain.
QO endurance-ready carbon cranksets offer the perfect blend of stiffness, weight, and versatility to tailor your gravel bike for any challenge.
