MEROCA M4 4-Piston Mountain Bike Hydraulic Disc Brakes Hydraulic Bike Brakes Front 800mm and Rear 1400mm with PM Adapter for 160mm Rotor

These are on my wife's bike. The groups are very similar to my Shimano hydraulics, they're quite nice and much less expensive. These were very easy to set up, stop well, and have a nice feel. They fit her small frame with lots of extra hose. We left the organic pads since my wife didn't want too much initial bite, and they stop perfectly fit her.

These fit the razor line of bikes with 160mm rotors. They include the adaptors which is really nice. They work awesome. Much cheaper option compared to other name brand brakes. I bought 2 pairs for both my razor mx650 and rsf650.

I love these so much they are so much better than I expected. I got the front / rear split for $55. They feel nice the stock brake pads bite pretty hard at first which I don’t prefer but that’s a personal preference. They also look pretty cool on my bike.

I can tell their good brakes but this product needs videos on how to work it because its so complicated to figure out how to bleed it and put new oil in

Works great installed on my ridstar Q20 fits great works great 😊

It’ll work on what’s it’s meant for but not for a mm-80 minibike frame, super close fit though and with some fabrication works great

very good brakes especially for e-bikes they’re 4 pistons. about twice as strong as rtr brakes

Brakes aren’t that great. Bolts strip easily, cheap metal

Very good

Alles bestens, sehr zufrieden
