SHIMANOUnisex Rotor Rtmt905 6 Bolt 203mm Bicycle Parts, Silver

My e-bike (a Tesway X7-Pro) came with 180mm rotors and 2 piston hydraulic brakes. Which most of you would realize is a fairly capable braking system in its own right. However, the X7-Pro has a 60Ah battery, so to call it a "heavy bike" would be an understatement. Plus I added a trailer hitch and pull a trailer with it, so I decided I wanted the absolute pinnacle of braking performance on my bike.It took a rather lengthy battle of finding the correct front caliper bracket (my bike has IPS mounts, which can be a pain trying to match up nowadays), but I have now installed this rotor (the XTR) on the front of my bike, and I went with the XT version for the back, which looks identical, to save a few bucks while still having decent performance. I also upgraded the 2 piston calipers to 4 piston calipers.The initial braking force is similar to the 180mm rotors, however braking force ramps up much more quickly with these 203's, and when you pull on the brakes hard, the bike brakes REALLY hard. Much harder than before, for sure. I definitely feel safer hauling down the weight of a trailer with these rotors installed.My only complaint is they're a bit noisier than my old rotors, but the pad engagement is perfect front and rear with my setup, so I can live with them being a bit noisier, as I know everything else is good.In all, 5 stars. It's been a very worthwhile upgrade for my X7-Pro, well worth the time and effort, and I highly recommend this rotor.

Excellent rotor, runs cooler than previous versions. A bit pricey compared to other brands but works as intended.

I just picked up a set of saint brakes and decided to use these rotors... So far they have been great... Very very very true... Most of the rotors i have gotten in the past always have a bit of wiggle in them.. so you have to true them before use.. Didnt have to do that with these....

Best shimano rotors you can buy!

Great working rotor, looks even better in person. Much thinner than Magura rotors.
