CRANK LENGTH
It is important to use the correct length of crank to ensure that your legs can work efficiently. You risk damaging your knees if you habitually use cranks which are too long, especially as you get older. 170mm cranks, which most cycle manufacturers fit as standard to most bicycles, are unsuitable for anyone shorter than the average European adult male and are therefore too long for most people in the World!

Normally fit adult riders should use cranks which measure about 20% of their effective leg length, rounded to the nearest 5mm, whereas growing children can safely increase this figure to 22%. This length goes all the way to your hip joint and cannot be measured directly. Ask a friend to measure your height twice - first when you are standing upright against a wall, without shoes on, and second when you are sitting squarely against it. Then subtract one measurement from the other one, as shown below.

The following table shows recommended crank lengths for normally fit riders on upright bicycles, based on the 20% to 22% range. Even shorter cranks may be required by disabled riders with restricted knee movement and by users of faired racing recumbents (due to space restrictions). Additionally, riders with very long legs may need shorter cranks on standard upright bicycles, to prevent their toes hitting the front wheel or their pedals hitting the ground when cornering.

Note that, not only do riders with shorter legs need shorter cranks, they also need smaller chainrings and will ride slower than riders with long legs and long cranks (rear cranks on tandems are an exception to this). Never try to achieve a higher gear ratio by using longer cranks.

As you can see the 94mm PCD cranks are more versatile, allowing us to mount a very big number of chainring combinations: 44-30, 46-30, 48-32, 48-34, 50-36, and so on. Among the combinations are those of the “classical” compact cranks mounts.

Advantages of using a 94mm PCD compact crankset:

1. Extend the crankset lifetime, giving more value to your invest. Just no change the cranks, only mount different chainring combinations.

2. For Cyclotouriste, touring bike or touring ride and, for recumbent bikes.

3. When you are or over 44-old years and your fitness and recovery times are not like in your young years.

4. As Mariner Fan writes: “It's all about options. Having an extra low gear just gives you an escape from a tall hill when you are beat. I live in the Midwest where I never go out of my big ring but I want to ride the hills as well. Gees, it's not a big deal. Bikes are meant to be ridden and I don't care what the younger folks think of me.”

5. This cranks gives you the opportunity to mount a 30‑tooth “granny gear”, try that for touring and hilly centuries.

6. Also suitable for those who are improving their low fitness, for age, for injuries, health or just due to medical advice…
