I am writing this review after few months of usage. These brakes are very good. Braking is amazing and with Shimano brake levers it work fantastic. I don't want an expensive hydraulic brakes but want disc brake so I chose this. It comes with resin brake pads with ice technology. Resin brake pads are amazing and working fine for me, no sound and crisp braking. For those who want more braking can switch to semi metallic brake pads but you have to buy separately. For front calliper, it can take 140 and 160 disc rotors but for rear calliper, it takes only 140 rotor. If you want to install 160 rotor at back then we need to buy adapter separately. For front calliper , they are including adapter.
Regarding mounting bolt, for front calliper, there was no issue with the length of mounting bolts and it will be no issue for most of the bikes but for rear I had issue with the length of the bolt. My road bike needs smaller length mounting bolts but with Shimano it has long and the only mounting bolts. Luckily I had correct size mounting bolts came with the bike. So do check that before buying since it only provide one set of bolts.
I guess most of people will know this, for those who didn't know, let me tell you that these are flat mount calliper those you can see on road bikes. Please do check before buying.
At last I am very happy with the performance of these brakes.
