Is PF30 better than BB30?

PF30 was developed to work in carbon fiber BB shells better than BB30, but use the same oversized, lightweight spindled cranks. It’s some BB30 size bearing housed in a protective nylon sleave that decreases the amount of force needed to press and hold the BB.

What does PF30 mean?

PF46 (also known as PF30, PF30a, PF30ai, BB386EVO, OSBB, BBright™ Press Fit) The term PF46 refers to a frame shell bore of 46mm.

How do I know what crankset to buy?

Cranks come in a range of sizes, most commonly from 165mm to 190mm, and ideal crank length is often determined by three factors: your height, your cycling discipline and your personal preferences. If you change your crank length, it will change how it feels to pedal your bike, and it may change your fit on your bike.

What is PF30 frame rate?

PF30 (30 frames per second sequenced as 60i) may be easier to use if you only intend web distribution. You can skip the deinterlace step. 30p will look more jerky on an HDTV and won’t work as well for frame interpolation to 120p or 240p. 30p mode will require a tripod or other camera stabilization.

Are shorter cranks better?

Crank length can be used as a tool to improve fit related issues impacting comfort, power, and aerodynamics. Moving to a shorter crank can improve: Comfort: A shorter crank length reduces range of motion at the knee (extension and flexion), hips, and low back.

How do I know what size crankset I need?

Crank length: This is measured from the centre of the bottom bracket axle to the centre of the pedal axle. Most stock bikes have cranks of 170mm or 175mm, but you can get them as short as 140mm and as long as 190mm. Choose crank arms that suit your inside leg measurement for optimum comfort and control.
