How do I set power-based training goals?

The best way to set power-based training goals is by consulting a cycling coach or using apps like TrainerRoad. It can create a structured training plan based on your season goals. You can learn more about it in my <a href="https://www.cyclistshub.com/trainerroad-review/" data-type="post" data-id="12957">TrainerRoad review</a>.

How often should I be doing power-based training?

The frequency of power-based training will depend on your specific goals and current fitness level. I recommend consulting with a cycling coach or using apps like <a href="https://www.cyclistshub.com/trainerroad-review/" data-type="post" data-id="12957">TrainerRoad</a> to create a training plan based on your preferences.

Can I do power training with an indoor trainer?

Yes, you can do power training on an indoor trainer. I recommend having an <a href="https://www.cyclistshub.com/best-smart-bike-trainers/" data-type="post" data-id="9875">interactive smart trainer</a> with an ERG mode feature. It will adjust the resistance based on your cadence and prescribed power. If you don't have a smart trainer, you can still do power training at home. However, you will need a power meter and a bike computer.

How do I measure progress in power-based training?

You can measure your progress by comparing your power output during specific rides or training sessions or, even better, by doing an FTP test regularly.

What equipment do I need for power to weight training?

A power meter with a bike computer is a must for power zone training. The power meter will measure your power and send it to the bike computer to display it. I also recommend combining your power data with your HR data. You can read my "<a href="https://www.cyclistshub.com/power-meter-vs-heart-rate/">power vs. heart rate</a>" article to learn more.

Are there any disadvantages of cycling with a power meter?

Yes. The first disadvantage is the relatively <a href="https://www.cyclistshub.com/why-are-power-meters-so-expensive-costs-breakdown/" data-type="post" data-id="17817">high cost of power meters</a>. Some people also argue that riding based on your power data is too predictable and less fun.

Crank Length Calculator

Q: How does this calculator work?

The power to weight used in this calculator are based on research and work by Andrew Coggan, Ph.D. Zone 1: <55% of FTP (active recovery) Zone 2: 56-75% of FTP (endurance) Zone 3: 76-90% of FTP (tempo) Zone 4: 91-105% of FTP (lactate threshold) Zone 5: 106-120% of FTP (VO2Max) Zone 6: 121-150% of FTP (anaerobic capacity)

Enter your inseam length to calculate your crank length using the ‘Machine’ and Lennard Zinn Methods. For calculating your crank length using the Graeme Obree method, include your height as well.

Unit: cm in

Please remember that this calculator provides estimates and should only be used as a general guide.
I recommend seeing a professional bike fitter to discuss the best crank length.

How to Measure Inseam Length?

To measure your inseam length, follow these 5 simple steps or watch the video below:

Prepare a 0.75 to 1-inch (1.9-2.5cm) thick book and a tape measure.
Take off your shoes and stand with your back to the wall.
Put the book in your inseam, firmly pull it up, and hold it with your tights. Make sure the book is pressed against the wall on one side.
Measure the length from the top of the book to the floor.
Take the measurement.

NOTE: The inseam for choosing the right bike size is different (a few inches longer) from the inseam used to choose the pants’ size. Remember that inaccurate inseam length may affect the recommended bike size.

Crank Length FAQ

What are the most common crank lengths?

The most common lengths are 165, 167.5, 170, 172.5, and 175 mm. But some manufacturers produce even shorter or longer cranks.

What is the ideal crank length?

The ideal crank length is not a one-size-fits-all measurement; it varies from one cyclist to another. Several factors come into play when determining the optimal crank length, including the cyclist’s height, leg length, riding style, and personal preference.
For cyclists with longer legs, longer cranks might provide a more comfortable pedaling motion, allowing for a better extension of the legs during each stroke. On the other hand, cyclists with shorter legs might find shorter cranks beneficial, as they can reduce strain on the knees and enable a higher cadence.
Additionally, your riding style also matters. For instance, mountain bikers often prefer shorter cranks to improve ground clearance and navigate challenging terrains more effectively. In contrast, road cyclists might prioritize longer cranks to maximize power output during long rides on smooth roads.

Are shorter cranks better?

Shorter cranks can benefit some cyclists, reducing knee strain, enabling a higher cadence, improving ground clearance, and enhancing comfort for those with limited hip flexibility. However, the ideal crank length varies based on individual factors. I recommend consulting a bike fitter to determine the right crank length for your specific needs.

Does crank length affect saddle height?

Yes. Crank length affects saddle height. Shorter cranks result in a lower riding position, which is usually more aerodynamic, and vice versa.

How does this calculator work?

This crank length calculator uses multiple formulas to recommend your crank length:
• Graeme Obree method: crank length = 0.95 × your height
• ‘Machine’ method: crank length = 1.25 × inseam + 65
• Lennard Zinn method (upper end): crank length = 2.16 × inseam
• Lennard Zinn method (lower end): crank length = 2.10 × inseam
