What is the L screw on a derailleur?

The L-limit stops the derailleur from moving inward (toward the spokes). The limit screw does not make the derailleur move, pulling the inner wire makes the derailleur move. The L-screw allows the pulley wheels to shift the chain to the innermost sprocket and yet not shift off the sprocket into the spokes.

How do you adjust H and L screws?

First turn the H-limit screw count-clockwise a few turns. Pedal and see if it makes the shift outward. If it still does not shift outward, turn the barrel adjuster on the derailleur body clockwise a few rotations. Pedal to see if it shifts.

What does H and L mean on a derailleur?

You need to adjust the high (H) and low (L) limit screws on the derailleur. Viewed from behind the bike, the H screw limits how far the derailleur can move to the right, while the L screw limits how far the derailleur can move to the left.

How to set up an SRAM front derailleur?

To set up an SRAM front derailleur, you’ll need 4mm and 2.5mm hex keys. What you need to know when we start is that the front of the mech cage moves more than the back of the cage. The reason for this is that it then means we don’t have to trim the front mech when we ride, as you should not get any chain rub.

How do you adjust the limit screw on a rear derailleur?

If the limit screws are unmarked, pick one and turn it in and out while watching the derailleur. If the derailleur does not move, try the other limit screw. The H-limit screw will cause the derailleur to move. Find the correct setting by first making the H-limit screw adjustment too tight.

What are the two gear screws on a rear derailleur for?

Both front and rear, the higher of the two gear screws trims the derailleur’s low gear position, and the lower screw trims its high gear position.
