If it isn’t set accurately, you may find yourself dropping your chain off the large ring and onto your crank arm—not one thing you need taking place mid-ride!

Here is what to do:

• Shift into the smallest cog on the again and largest chainring on the entrance.
• Use a small Phillips head or flat blade screwdriver (relying in your mannequin) to show the excessive restrict screw.
• Flip clockwise if you have to limit derailleur motion (if it’s pushing too far previous the large ring).
• Flip counterclockwise if you have to enable extra outward motion.

It is all about discovering that candy spot the place there’s minimal hole between the chain and outer a part of the derailleur cage when on this gear combo—however with none rubbing or noise indicating contact. A very good rule of thumb is leaving a few 1mm hole; any much less would possibly trigger friction and have an effect on efficiency.

Keep in mind that these changes are delicate; even half a flip could make a noticeable distinction.
