Power. A shorter crank alone will not increase your power output, but it can be used to reduce restriction through the top of the pedal stroke by opening up an impinged hip angle and/or reducing knee flexion.
Can crank arms be too short?
Using cranks that are too long can cause cycling discomfort and injuries, especially when riding longer distances, due to excessive articulation of the knee and hip at the top of the pedal stroke; using cranks that are too short is far less likely to cause problems.
Will shorter cranks help my knees?
Pain is relieved. Just by installing shorter crank arms, without any other adjustment, the knee at maximum flexion is lowered by 7.5 mm.That difference provides approximately 3° to 4° of relief.
The number of teeth on your chainring(s) is a deciding factor in your bike’s gear ratio, with a greater number of teeth meaning a higher (harder to push) gear, and fewer teeth meaning a lower (easier to push) gear.
How many teeth should my cranks have?
Standard cranksets are typically 53T/39T. In most cases, you can change your chainrings to have different tooth counts, but as a general rule you don’t want to have more than a 16-tooth difference between the big ring and little ring or you may have shifting issues.
