What’s the Ideal Crank Length for Time Trial Cyclists?

Wiki Article

If you're into time trial cycling, you've probably spent a lot of time thinking about your bike setup—your position, helmet, and maybe even your skin suit. But one part that often gets overlooked is crank length. Picking the right crank length can make a surprising difference in your comfort and performance during a time trial. If you’re exploring gear options, websites like https://mickeycranks.com can help you compare choices based on your needs.

So, what is crank length, and why does it matter? Simply put, it's the distance from the center of the bottom bracket (where your pedal rotates) to the center of the pedal axle. Most standard cranks come in lengths between 165 mm and 175 mm. The idea is that shorter or longer cranks can change how your legs move and how your hips and knees feel while pedaling.

For time trial cyclists, many people now lean toward using shorter cranks—think 165 mm or even shorter. The reason? Comfort in the aerodynamic position. With shorter cranks, your knees don't come up as high at the top of the pedal stroke. This often allows for a more comfortable and lower tuck on the bike, which can reduce drag and help you go faster with the same effort.

Shorter cranks can also help reduce pressure on your hips and back, something many time trial riders struggle with when trying to hold that forward-leaning position for long periods. On top of that, they often let riders spin at a higher cadence, which can lead to a smoother pedal stroke and less fatigue.

That said, going shorter isn’t the answer for everyone. Taller riders or those with long legs might still find a sweet spot with slightly longer cranks. It’s all about finding what works best for your body and your riding style.

In the end, the "ideal" crank length is the one that helps you stay comfortable, keep a steady effort, and hold an aero position without pain. It's worth testing different lengths if you can. Small changes can bring big improvements in how you ride and feel on the bike. Try a few options, see how your body responds, and go with what feels right for you.
