Shifters

Cysky Bike Shifter 3x7/3x8, links en rechts

The Cysky Bike Shifter covers left and right sides for 3x7 or 3x8 speed bikes. The brake combo is built into the lever, so you get a full set for your handlebar.

Why a good shifter?

You shift dozens of times per ride, often with cold or wet hands. A shifter that clicks clearly and responds quickly makes the ride easier. A worn or dirty shifter skips gears or needs too much force.

On a drop bar you use a combined shifter and brake lever, often called a brifter. On an MTB or flat-bar gravel bike these are triggers you work with thumb and forefinger. Twist grips are less common. Bar-end shifters also exist, sitting in the end of the bar, mostly on touring bikes.

The shifter has to match your derailleur and the number of speeds. Each brand has its own cable pull ratio, so a Shimano shifter with a SRAM derailleur shifts badly. With electronic shifters the switches and battery set the feel, and they pair with a matching derailleur.

A brifter also brings the brake. For hydraulic disc brakes there is a small oil reservoir in the lever. For mechanical brakes it pulls a cable. So you need a brifter that suits your brake type.

How the types compare

The type of shifter depends on your handlebar and how much upkeep you want to do.

Type	Handlebar	Feel	Watch for
Mechanical brifter	Road or gravel drop bar	Clear click, cable tension needed	Replace cables and housing
Electronic brifter	Road or gravel drop bar	Light, same pressure each time	Battery and matching derailleur
Trigger (thumb and finger)	Flat MTB or gravel bar	Quick, several gears per push	Tied to a specific derailleur
Bar-end shifter	Straight or drop bar ends	Simple, sometimes friction	Hands leave the bar to shift

Check that the shifter matches the brand and number of speeds of your derailleur.

Choose it if

You want to renew both sides of your handlebar in one go.
Your bike has a 3x7 or 3x8 drivetrain.
Your shifter skips gears, feels soft or no longer clicks.
You want to move to a different number of speeds or to electronic.

Choose something else if

With a modern 11 or 12 speed groupset you need a shifter from that range.
The problem is in the cable or housing: that is easier to fix than replacing the shifter.
You do not know which derailleur you have. With an unknown pairing, shifting often fails.

How to fit a shifter

Check the pairing
Check that the shifter matches the brand and number of speeds of your derailleur and your brake type.
Mount it on the bar
Slide or clamp the shifter onto the bar at a height your fingers can reach. Do not tighten it fully yet.
Route the cable or wire
Route the cable in a gentle curve to the derailleur. For electronic systems, plug in the wires and check the pairing in the app.
Tension and shifting
Set the cable tension with the barrel adjuster on the derailleur or shifter so each click gives one gear.
Tighten
Tighten the clamp to the stated torque, usually 5 to 8 Nm. Test while riding and make sure the brake works properly.

Good to know

The listing mentions left and right, so confirm both levers are included.
Check that your brakes (V-brake or mechanical disc) suit the brake combo.
Replace cable and housing every year. A dirty or stretched cable is the most common reason a shifter shifts badly.
Mind the number of speeds: a 10-speed shifter does not drive an 11-speed derailleur well.
With hydraulic brifters the brake must be bled if you remove it or change the hose.
Electronic shifters have a battery you must charge or replace. Do not mix unknown brand combinations.
