A rachet involves a round gear or a linear rack with pearly whites, and a pivoting, spring-loaded finger named a pawl that engages one’s teeth. The teeth are uniform but asymmetrical, with each tooth having a moderate slope on one edge and a very much steeper slope on the different edge.
When one’s teeth are moving in the unrestricted (i.e. forward) way, the pawl without difficulty slides up and over the smoothly sloped edges of the teeth, with a springtime forcing 
it (frequently with an audible ‘just click’) into the depression between the teeth since it passes the tip of each tooth. When one’s teeth move in the opposite (backward) direction, on the other hand, the pawl will capture against the steeply sloped advantage of the initially tooth it encounters, therefore locking it against the tooth and avoiding any further motion in that direction.
Backlash
Because the ratchet can only stop backward action at discrete points (i.electronic., at tooth boundaries), a ratchet does enable a restricted Ratchets Wheel amount of backward movement. This backward motion-which is bound to a maximum range add up to the spacing between your teeth-is called backlash. In cases where backlash should be minimized, a clean, toothless ratchet with a higher friction surface area such as rubber is sometimes employed. The pawl bears against the top at an angle so that any backward action may cause the pawl to jam against the surface and therefore prevent any more backward motion. Since the backward travel length is mostly a function of the compressibility of the high friction surface, this system can lead to significantly reduced backlash.
This Ever-power 54t Ratchet kit works as a direct replacement and is super simple to install. Just take away the freehub body the parts you find here will be in there, grease up the new parts and re-assemble the hub. Boom! You’ve merely significantly increased the engagement things on your hub. To provide you with a better idea of how this increases your ride think of the engagements in levels of a circle, with the 18t you’ve got to move the cassette 20 degrees to attain the next engagement and with the 54t that knocks it right down to 6.66 degrees! That’s less than a 3rd the distance it needs to go to hit another tooth! You may be wondering when you can really see the difference. Merely pedal your motorcycle around and keep carefully the bike moving by using little pedal strokes and back-pedaling. You’ll see there’s going to become lot’s of slop between engagements. Envision if that “slop” was decrease to a third! I’m sure imaginable that’s a huge upgrade. Therefore, in the event that you weren’t already completely convinced on the 54t ratchet package I hope it is the turning indicate getting one!
