What is Chainline Q factor?

What is a good Q factor

Good high-Q capacitors can have a Q factor value of over 10,000 at 1MHz and over 1,000 at 100MHz, while standard capacitors can have a Q factor as low as 50 at 1kHz.

What should Q factor be

Due to bottom bracket size, minimum chainline guidelines and chainstay length, there is an acceptable range for Q-factor, which is typically between 150mm and 170mm. Road bikes tend to have a narrower Q-factor (150mm), while mountain bikes tend to have a greater Q-factor (170mm).

What does 50mm chainline mean

this is all referring to the below diagram. as you can see, the front ring is 50mm from the middle of the bike (aka, a 50mm chainline). a standard rear end is 135mm between the droputs, meaning that each drop out is 135/2 = 67.5mm from the center of the bicycle.Nov 25, 2009

What is chainline measurement

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.

What is a large Q factor

Q factor is the overall width of an installed crankset, measured parallel to the bottom bracket shell from the outside of one pedal insertion point to the other. You can think of it like this: the larger the Q factor, the farther apart your feet will be.

What should my chainline be

The bike center line is an imaginary plane running front to rear through the middle of the bike. For example, a front crankset and/or front derailleur might be designed to have a chainline of 47.5mm. This means it will work best when the middle of the crankset is 47.5mm from the middle to the bike center line.

What is a 50mm chainline

as you can see, the front ring is 50mm from the middle of the bike (aka, a 50mm chainline). a standard rear end is 135mm between the droputs, meaning that each drop out is 135/2 = 67.5mm from the center of the bicycle.Nov 25, 2009

What is a high Q factor

Q factor describes if an oscillator or resonator is underdamped, overdamped, or critically damped. Higher Q indicates that the oscillations die out more slowly (a lower rate of energy loss relative to the stored energy of the resonator).

What is a high Q cavity

Physicists use a number, called Q, to characterize how well an optical cavity stores light: the higher the Q, the longer light stays confined in the cavity. … But, if the light waves from different channels destructively interfere, then no light leaks from any of the channels. Hence, a high-Q cavity is born.

Is a narrow Q factor better

Many crank manufacturers make Q-factor as narrow as possible for improved aerodynamics and benefits to bicycle's design—they don't address the rider's interface with his or her bicycle. … This rider's stance width is too narrow; the knees are much wider than the center of the pedal body.
