You will have to get a buddy to assist make this happen. Sit on the bike and question them to established the B-rigidity if you are sat thoroughly weighted over the bike.
Holding pressure on the cable, wind out the screw a half flip at a time right up until the chain jumps to the largest ring. Immediately after this, quarter turns will permit you to change the derailleur so it doesn’t rub the chain.
Rotate the cranks. The chain should really roll cleanly around the smallest sprocket and thru the rear derailleur cage with no catching or skipping. Now test the total array of gears one after the other. It is possible to once in a while have the cable tension spot-on 1st time, but you'll normally have to make some great tuning changes to the cable tension While using the barrel adjuster.
If your chain rubs to the outer plate then you must tighten the cable by turning the barrel adjuster anticlockwise simply enough to halt rubbing.
Placement the entrance derailleur so the outer cage is one-3mm over the enamel of the large chainring. The outer cage also needs to be parallel for the chainring enamel. Examine the angle within the front to be certain it is not tilted much too much inward or outward.
The high and minimal limit screws are compact screws Found on the rear derailleur entire body. They serve as adjustable stops, limiting the movement array of the derailleur.
With The stress removed from the cable, check here convert the pedals. The rear derailleur should really shift the chain to operate on the smallest rear sprocket, and also the upper jockey wheel from the rear derailleur must be specifically beneath the smallest sprocket.
With the derailleur now sat at the smallest cog (highest equipment) with the back again. Adjust the higher Restrict screw until eventually the upper jockey wheel is aligned With all the smallest cog.
Be mindful of gear variety and prevent "cross-chaining" by using Severe mixtures (substantial chainring and enormous rear cog or vice versa).

Change to the largest chainring and regulate the large Restrict screw until finally the chain is aligned and would not rub towards the outboard arm on the cage (While at the bottom in the cassette).
When you’re unsure in which to begin, jump to our guide regarding how to diagnose and correct frequent shifting issues with your bike gears at the conclusion of this text.
Then, push the derailleur to the biggest cog (least expensive gear) by hand when pedalling the bike. Modify the very low limit screw right up until the jockey wheel strains up with the largest cog.
Restrict screws – These are typically two adjacent screws Positioned over the again of your respective derailleur. They change the utmost limit the chain can move outside the bottom and optimum gears.
