CNC Rear Derailleur 10 Speed Direct Mount/Hanger Mount for Shimano/sram

I bought this to repair my old mtn bike. I am a certified bike mechanic, and have built and repaired hundreds of different bikes, from kids bikes to $10,000 road race bikes.I was wary about the quality because of the dirt cheap price. I did not expect much. Boy was I wrong!!!This is an incredible value. The shifter and derailleur are great quality and the shifting is buttery smooth. I've taken this set on some knarly rides and the shifting is phenomenal!The photo is a $6500 mtn bike that I just built for a customer, with a custom frame. I tested this derailleur and shifter on this bike to see how it worked, and it was great!Super quality and surprising performance for the price! I just hope they don't raise the price after learning this!

I bought this to replace a Shimano SLX 10 speed shifter, which operates with a thumb push to upshift and trigger to downshift. This shifter uses a thumb push to both down and upshift. I did not want to take a chance getting used to this, so I returned it. Quality looked decent and it came with the cable installed. It does make a very pronounced click sound when it shifts

Not sure if the problem is with the derailleur I’m using with or it’s that the shifting is not accurate. I’m using with a 10speed cassette and when I shift from high to low, the chain skips about 2 plates.Apart from that, it works just fine and good for the price.

Installed this on my mom’s Terratrike Rambler that came with a SRAM micro shift 10 speed, and it works great with some fine tuning. She needed the shift indicator for ease of operation. I would definitely buy again

I have used the AX11 on 3 different builds, excellent product. This derailleur... not so much. B limit screw bent under the strain of its own expectations. The mostly plastic build leads to a lot of issues when it comes to adjustments. To be fair, I was trying to use this with a 10 speed 52 tooth cassette. But to be honest adjusting it on the high end of the cassette was downright impossible so not sure if the cassette choice was really the issue. AX11 is on its way so nbd, lesson learned.

Used a 1071 sram pc chain, and put on as was without removing any links. A 1.5 inch bicycle derailleur hanger extender. Added 12t aluminum narrow wide jockey wheels which needed washers added by me on either side. Used a 30t narrow wide round front sprocket. Used a 11-50T 10 speed rear cassette. Shifted great with each click of shifter up or down. Only got to shift with each click up to the 50t rear cog with a 1.5 inch rear derailleur hanger extension not the 1 inch that came with the cassette.

The derailleur adjustment screws are metal and the threads plastic. If this product used metal instead of plastic it might be a decent derailleur. I got it shift a few times but when adjusting it the plastic threads gave out.Don't waste your moneyI wish I saw a bad review like this before I purchased it

When Paired with the same brand derailleur it's made for a shifting experience I've never known before Chrisp clean quick, no lag nothing perfect shifting mechanism for a mountain bike
