Q-Factor: Foot Stance
The Q-Factor is the value given to the stance of your cranks and feet. This
width in general should be small - the closer your feet are to the bottom
bracket the better. The shoe should pass as closely as possible to the crank.
The Ergon TP1 can help set this distance.
Please note that if you are to ride with overshoes, then adjustments may be
required accordingly.
Expert Tip:
Many cranksets and different types of bikes have extremely wide Q-Factors.
This can make it difficult to position your feet optimally relative to your pelvis
and lower limb biomechanics. In this case a different crankset is
recommended which offers a lower Q-factor. This is particularly important for
smaller riders and people with a narrow pelvis.
