Pros & Cons

Update Pros and Cons

Pros

Bought this to replace my stock derailleur on a mongoose terrex. Fared better than someone's pricey shimano on a very pricey giant hard-tail frame. Works fine on my semi recumbent sun easy rider bike.

Shifts fast enough for my cheap rig. Not a huge fan of the thumb only sram shifter though, but it's required for this derailleur.

First impression are- well made metal construction and heavier than the sun tour. Seems like decent quality, fair amount of plastic on it. Sturdy and beautiful.

Cons

Big disappointment. Snapped my chain as well. This thing is junk.

Price

I have 0 complaints, especially at this price point.

And for the money (about $60 all together for the swap) it's a great deal considering it made my used bike feel brand new again!

For a low cost derailleur it is pretty smooth.

If you're building bikes with an eye toward cost, listen to the kinks' 'low budget.

I sent a picture of the derailler with the missing b-bolt, and they sent me a replacement!

I have x9s and they don't work a bit better.
