Rear derailleur limit screws demystified: A simple guide!

Get ready to master the art of rear derailleur limit screws! In this video, I’ll dive deep into limit screws demystified and show you exactly how to adjust the ‘H’ and ‘L’ screws for optimal performance.
Every rear derailleur has two crucial screws that set its movement limits, protecting the chain from overshooting the gears. Without these screws, your derailleur could push the chain off both the smallest and largest cogs.

I’ll guide you step-by-step, showing you how to spot and adjust each screw.
The ‘H’ screw (high gear) prevents the chain from falling off the smallest rear cog, while the ‘L’ screw (low gear) keeps it secure on the largest.

When should you check the limit screws? During initial setup on a new bike, after replacing the derailleur, or if you notice gear alignment issues.
Follow along as I cover each step, from loosening the gear cable to fine-tuning the high and low screws.
I'll walk you through the process, offering troubleshooting tips to keep everything aligned.
