What is standard Q-Factor?
Sometimes known as ‘quack factor’ (a references to ducks and their waddle-y legs), Q Factor is the distance between the outside of one crank arm to the outside of the other. This is an important bike fit parameter as it effects your stance width, which is how far apart your feet end up being when placed on your pedals.
What is Q-Factor in MTB?
Essentially Q-Factor is the distance between the pedal attachment points on the crank arms, also referred to as Tread. It could also be described as the width of your crankset. This affects your stance, if you’ve ever been snowboarding think of it as the same thing, essentially the distance between your feet.
What is bike crank Q-Factor?
Simply put, Q-Factor on a bicycle is the distance between the outer surfaces of the crank arms. This affects how far apart the pedals are, which in turn affects the biomechanics of pedaling and the handling of the bike.
What is Chainline Q factor?
The Q factor of a bicycle is the distance between the pedal attachment points on the crank arms, when measured parallel to the bottom bracket axle. It may also be referred to as the “tread” of the crankset. The term was coined by Grant Petersen during his time at Bridgestone Bicycles.
How does Q factor affect cycling?
“Increasing your Q-factor increases your stance width and decreases your Q-angle.” It’s your total stance width that you need to pay attention to as this affects how it feels to pedal. As stance width is affected by Q-factor though it’s worth understanding how this value is landed on.
How does Q-factor affect pedaling?
What is chainline Q-factor?
How does Q factor affect pedaling?
How do I reduce the Q factor on my bike?
The easiest way to reduce your Q factor is to install a shorter bottom bracket. There are many good, inexpensive square-taper BBs available in different lengths. You could pull the cranks off your present BB, measure them, and then order a shorter BB.
How do you calculate chainline?
Chainline is measured from the centerline of the frame to the center of the chain. You can measure the front chainline directly with a simple ruler. Simply hold the ruler against the seat tube or down tube and measure the distance from the middle of the seat tube to the middle of the chainring teeth.
What is the correct chainline?
Chainline is the distance between the centerline of your frame and the average centerline of your chainring(s). For 1X this is easy – If the center of your chainring teeth is 49mm from the centerline of your frame then your chainline is 49mm. It gets slightly more difficult if you have multiple front chainrings.
What is Q factor of a circuit?
The quality factor Q for the circuit is the electric energy stored in the circuit divided by the energy dissipated in one period. The Q of a circuit is an important quantity in certain applications, as in the case of electromagnetic waveguides and radio-frequency cavities where…
Do I need a wider Q-factor?
Be careful changing your stance width “Some people find when they go from a mountain bike to a road bike because the Q-factor has decreased and the Q-angle has increased, that can sometimes lead to issues like ITB pain and problems like that. “Going narrower can increase the strain on our lateral structure.”
How do I reduce the Q-factor on my bike?

What is Q factor on a bike?
Q Factor is the distance between the outside of one crank arm to the outside of the opposite crank arm. Although Q Factor has become a universally recognised measurement, other people in the bike trade prefer to use a value for ‘stance width’ — which refers more directly to the distance between feet on the pedals.
