Begin with your chain in the outer chainring, and shift until you’re in your hardest gear. Now, using a phillips head screwdriver set your outer or H-limit screw. The best way to do this is looking from the back of the bike, turn the limit screw until the jockey wheels sit just outboard of the smallest cog. This will help the derailleur shift easily into your hardest gear.

Shift the chain to the second smallest cog at the rear and the big ring up front. Without turning the pedals, shift up into the smallest cog. This will give you a bit of cable slack. Holding the derailleur, undo the bolt holding the cable in place, and pull through until the cable is tight, but don’t yank on it as hard as you can. Now turn the pedals to allow the chain to shift into your smallest cog. This should leave your chain shifting perfectly.

For the front derailleur you are likely to have an inline barrel adjuster to fine tune your indexing, when you move the shift lever. You want the cable to be nice and snug in the cable clamp with a good tension and then slowly turn the barrel of the adjuster to help with that finishing touch to make sure the derailleur responds to the movement of the lever.
