Pros & Cons

Update Pros and Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

It has a good feel to it and has a break point (plastic bolt) to protect the derailleur. Previous one worked for 5 years until got bent. Everything functions smooth and bike is better than it was new.

Easy to install especially for a beginner like me! If you go on youtube and spend a little time messing with the adjustments you'll have this thing installed and working in no time. Adjustment was needed on the limit screws though.

Great replacement mech. Good upgrade highly recommend. Fast shipping too.

Shifts are quick and sure every time. It is on a relatively inexpensive bike, but it shifts well. Indexes fine with shimano combo shifters.

The old xt version predates my fairly new 8 speed cluster. Great shifter. Much greater than what i had working that was old and rusted.

Cons

The derailleur is not compatible with a 6-speed gear. The manufacturer doesn't offer a warranty.

Price

It was what it said and good price

This thing is stout for the price!

Shipping

Came a day earlier than projected from shipping info originally provided.

She saw, she wanted, she ordered it, it came fast with no issues.

Item arrived ok but the box was trashed due to poor shipping packing.

Competitiveness

I gave it 5 stars because of my previous experience with shimano products.

8-gear shimano cassette, 3 chainrings on front sprocket, old cannondale m1000 trail bike that i use for mostly on streets.
