Review on 🚲 microSHIFT MTB Mezzo RD-R45L: Long Cage 8 / 9 Speed Derailleur for Shimano-Compatible Bikes by Kenny Marozas

Works with travel derailleurs. I asked this question but I don't see it so I'm answering here. I have an older 105 9 speed cross bike and just mounted it on a stand. In addition, this switch has a long range. I use conservatively 34t for downshifting and I think this derailleur will rock at 40t and probably/maybe work with 10 gears. I don't have anything with 10 speeds at the moment so I can't confirm or deny that this would work, but then again I think you could make 40t 10 speeds out of it. 5 star rating. Will be updated.
