Verified Purchase(What is this?)
This review is from: Shimano Alivio RD-M410 Rear Derailleur - Black, Large (Sports)
I bought this whilst rebuilding a mountain bike for my daughter , the old gear was sloppy , sticky and noisy , but this Shimano unit bolted straight on and gave a perfect shift every time , it is really smooth and positive and needed only minimum adjustment .
It is well built and looks great .
