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

Good derailleur but requires disassembly of idler pulleys and lubrication of roller bearings before installation. The derailleur barely made it through the 36T gearing.

Easy installation on 90's refurbished MTB. Looks good and shifts well with the handlebar end shifter. However, he couldn't handle a 40-ton cassette, he thought he could.

I have a 2010 Trek 4500 mountain bike that I didn't want to invest too much money in. I converted it to 1x9 and replaced the worn Shimano bearing with a Microshift and it's just as good if not better. All for $20!

This rear derailleur is easy to like. The cage easily accommodated the 36T rear sprocket. Setting up with the Shimano levers was easy and changes went smoothly. It feels reliable and while you may eventually want to replace the idlers, for the money this is a steal.

I had to replace a damaged Shimano Acera rear derailleur but it has been discontinued. I didn't want to spend much so I decided to try this one. He exceeded my expectations! Looks great and shifts as well as Shimano if not better.

Nothing is more frustrating than trying to adjust old derailleurs and after a few hours of adjusting the cable tension, limit screws and bolt I gave up. Took this RD, installed and got through in under 10 minutes. It's nice to give an old bike a new life.

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
