# Question: What are the H and L on a bike?

Contents

H= High limit, L= Low limit. While on a bike stand, you can select different gears and set the limit screws so the chain can easily shift, but never fall off at the extreme positions of the gear shifter.

## What does H and L mean bike?

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. Unscrewing lets the derailleur move further in that direction; screwing in restricts movement in that direction.

## What does l mean on a bike?

The front derailleur is controlled by the left shifter. Many shifters are marked in some way, often numbered or with an ‘H’ for the high gear and an ‘L’ for the low gear. The ‘1’ or ‘L’ refers to the innermost chainring (closest to the bike).

## What does the H limit screw do?

The main purpose for the limit screw is to prevent the chain from going into the spokes or into the frame. Tightening the H-limit screw restricts the limit as shown. The goal is to dial it in as close as possible to the inward cog, as shown in the previous photo.

## How do you adjust H and L screws?

To adjust L-screw, pull on inner wire and shift outward one sprocket, then release inner wire to shift inward. Tighten L-screw until shifting is slow, then turn counter-clockwise 1/4 turn until good shifting is restored.

## Is gear 1 high or low on a bike?

Bikes generally have 1, 3, 18, 21, 24, or 27 speeds. (10- and 15-speeds are obsolete and you don’t see them on new bikes anymore.) Lower numbers are the low gears, and higher numbers are the high gears. First gear is a low gear.

## Which gear is hardest to pedal?

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.

## Do you shift gears while pedaling?

You must be pedaling when you change gears. That’s because the chain has to be moving in order for the derailleurs to “derail” the chain from sprocket to sprocket. If you click the shifters without pedaling, the gears won’t change until you do start pedaling, and when you do, you’ll hear some very disconcerting noises.

## When should I shift gears on my bike?

Tips for Proper Shifting

Anticipate the terrain: Shift right before you start climbing, not halfway up when you’re slowing rapidly and applying maximum pressure on the pedals. If you do shift on a hill, shift one gear at a time, and momentarily relax pressure on the pedals as you’re shifting.

## Which is the high limit screw?

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 is the barrel adjuster on a bike?

That’s a barrel adjuster, which is used to tune the derailleur adjustment. Standing behind the bike, the barrel adjuster is turned either counter-clockwise or clockwise in half-turn increments until the shifting hesitation is cured.

## How much does it cost to adjust derailleur?

Derailleurs – (per derailleur) \$20 labor for derailleur adjustment and lubrication. If cable and housing needs to be replaced, labor is \$25 plus the cost of the cable and housing. If a bent derailleur needs to be aligned, there is an additional \$15-20 labor cost.

## Do you adjust front or rear derailleur?

Do the rear first. You won’t be able to pedal the drivetrain in any gear other than the smallest cog otherwise. The adjustment of the front will depend on being able to get the chain not to rub on the front der cage as you run the chain across the cassette in back.
