Most bikes come stock with longer cranks than they need. Not because it’s better, but because it’s simpler to manufacture at scale.
Frame sizes are already split across multiple SKUs. Adding crank length options on top of that adds complexity most brands avoid. So they spec something “safe” for the average rider, even if it’s not actually optimal.

Longer cranks mean your feet travel further every pedal stroke. That usually leads to more hip movement, more knee flexion at the top of the stroke, and a higher chance of pedal strikes on trail.

Dialing in the right crank length for your body helps keep your movement more controlled and efficient. Less strain on your joints, better clearance in technical terrain, and smoother cadence.

And here’s the part most people don’t expect.
Shorter cranks don’t mean less power.

When they’re sized properly, they often let you produce the same power with better efficiency and less fatigue. For a lot of riders, that means stronger efforts over time, especially on climbs and longer rides.

That’s exactly why we built our cranks.
Adjustable length, so you can actually dial in what works for your body instead of settling for whatever came on the bike.
