Review by Lance
This derailer works perfect.

I changed my cassette to more of a hill climbing gear range. Had to change out the derailer, this is the only one I could find for a seven speed. It works perfect, shifts great.

Review by KC cyclist
One of the most used 7-8 speed derailleurs

Better than the entry level Shimano derailleurs and performs well. Quite durable, especially for the price. Typically used on $450-600 bikes and many e-bikes costing much more. Been around for a long time.

The tech I spoke with was very knowledgeable and helpful. He spoke bicycle. Tech made useful suggestions about the product to buy and best order to swap out parts.
