Sram eagle 50t/52t axs/mechanical rearderailleur chain adjustment tool

2025/09/05

Leszek (Poland)

A very good tool for precise adjustment of the SRAM Eagle 50T/52T mechanical rear derailleur (for a 50/52-tooth cassette with a chainring). Pros: Small and handy. Cons: Plastic is fragile. The first tool fell apart in my hands after four years. Perhaps it came into contact with oil vapor? We'll see how it goes with the one I'm currently using.

Very useful
