## Questions & Answers

**Q: sirve para 2x9 de 11-40?**
A: Trabaja bien para 3*9

**Q: Is this compatible for 8 speed?**
A: Not perfectly - the m3100 model is really meant for 9 speed

**Q: Will this replace the stx rc on a Trek 7300 8 speed?**
A: Shimano's Compatibility charts won't show this "9-speed" derailleur as compatible with 8-speed components, but it should work just fine. Shimano 8-speed shifters will work. This RD can handle larger cogs than were common in the 8-speed era, up to 36t largest cog, but assuming you have 11-32 it'll work. I have an stx rc RD on one of my bikes, and wouldn't hesitate to try this as a replacement.

**Q: Does it come with the hanger bolt?**
A: Hi - It does not.
