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 does H and L mean on a bike?
Chain overshoots 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.
What gear should you use going downhill on a bike?
High Gear = Hard = Good for Descending: The “highest” gear on your bike is the largest chain ring in the front and the smallest cog on your cassette (rear gears). In this position, the pedaling will be the hardest and you’ll be able to accelerate while traveling downhill.
How do you tune a rear derailleur on a bike?

How is the derailleur moved on a bicycle?
The derailleur is moved by tightening or relaxing the cable tension. The highest gear (smallest sprocket) on the rear derailleur is actually the point of lowest cable tension, meaning the derailleur is doing the least work and is thus easiest to adjust.
What to do if your rear derailleur is out of alignment?
Align It: If your chain doesn’t move when you shift, or it skips cogs, your rear derailleur may be out of alignment. Hop off your bike and do this: Shift your chain into the biggest chainring and smallest cog, then loosen the cable clamp bolt (where the cable attaches to the derailleur).
Where is the adjuster on a rear derailleur?
The barrel adjuster is the small cylinder connecting the cable to the derailleur. Follow your cable from the rear derailleur up to the handlebars. The tension on this cable is what actually causes gears to shift.
