The Tourney series from Shimano stands for durability and ease of maintenance in the entry-level segment. The RD-TY300 offers solid shifting performance for everyday use without compromising build quality. Compared to higher-end models, it lacks low-friction technology but impresses with simple adjustability and robust construction.

Ideal for hobby cyclists and commuters

This derailleur is the right choice for anyone looking for a reliable bike for commuting, errands, or leisurely rides. It suits beginners and experienced riders who value a straightforward and cost-effective shifting system. Not recommended for road bikes or mountain bikes with high gear counts.

How to mount and adjust the derailleur

1. Attach the derailleur with the direct mount bolt directly to the frame's derailleur hanger.
2. Connect the shift cable to the derailleur's cable clamp and tension it slightly.
3. Adjust the upper and lower limit screws so the chain does not overshoot the smallest or largest sprocket.
4. Fine-tune the cable tension with the adjusting barrel until each gear engages cleanly.
