Which way do you turn a barrel adjuster rear derailleur?

This rule will help you remember which way to turn it: If the derailleur is hesitating when shifting toward the spokes (the more common problem), turn the barrel toward the spokes (counter-clockwise); and if it hesitates shifting away from the spokes, turn the adjuster away (clockwise) from the spokes.

What do H and L screws do?

Your derailleur has two limit screws. For the outer limit, you adjust the H-Screw, so your chain does not fall between the cog and the dropout and for the inner limit, you turn the L-Screw, keeping the chain from derailing towards the spokes.

What do the screws do on a rear derailleur?

Derailleurs are fitted with limit screws that stop the derailleur from moving too far inward or too far outward. If you look closely as the derailleur moves, you can see the limit screws stopping the derailleur at each end of it’s travel.

What does a barrel adjuster look like?

Barrel adjusters are small cups that have a hole in the bottom, and are screwed into different points around your bike. They are usually located by your brake levers, brake calipers, gear levers, and derailleurs. They work by increasing the amount of distance an inner cable will travel.

Which way do you adjust a derailleur?

When adjusting limit screws, tightening (clockwise) the screws will always restrict movement of the chain outward and loosening the limit screw (counterclockwise) will allow the chain to move farther outward toward the spokes or dropout. The low limit prevents the derailleur moving in toward the spokes.

How do you adjust rear derailleur?

Step 1: Make sure the rear derailleur is shifted all the way down into the smallest cog. Step 2: Turn your barrel adjuster all the way tight so that you have room to adjust it later. Step 3: Adjust the high limit by rotating the screw on your derailleur marked “H” so that it lines up with that smallest cog.

Can I adjust my rear derailleur upside down?

The problem being is that gravity does have an effect on chain position and the rear derailleur cage position when the bike is upside down. It makes fine adjustment difficult. But it can be done. It’s just much easier in a stand.

How does a rear derailleur work?

The rear derailleur must shift between a greater set of gears. These gears or cogs make up the rear cassette, which is attached to the hub of the rear wheel. Like the front derailleur, the rear derailleur pushes the chain up or down the cassette after you engage the shifter.
