• The information pulley directs the chain onto totally different gears.
• The stress pulley retains slack out of the chain.

If you click on your shifter, right here’s what occurs:

1. A cable tightens or loosens,
2. Pulling on a linkage mechanism,
3. Which then strikes the whole derailleur meeting inwards or outwards,
4. Guiding the chain to your chosen gear.

The parallelogram design of most derailleurs permits for lateral motion whereas sustaining fixed angle relative to the cassette (the set of cogs at your rear wheel). This ensures that shifts are constant throughout all gears.

Sustaining correct adjustment is essential for easy operation:

• Restrict screws management how far left or proper the derailleur can transfer, stopping overshifting.
• B-tension screw adjusts how shut the information pulley runs to the sprocket.
