Teyssor140mm 160mm 180mm 203mm Bike Disc Brake Rotor with 6 Bolts Fit for Road Bike Mountain Bike BMX MTB

I needed to replace the rear brake rotor on my Emove Cruiser and this was a direct match. The included screws were slightly shorter than the originals, so I just used the originals.I've already put 400km+ on them and they've been great so far.

Good for light duty use, heavy. The 140mm weighed 106 grams.The material surface is low quality, but for the price, can't complain.

Noticeably different than the old disc which was worn thin and had groves. At one time it ran metallic brake pads, noisy suckers.The six included screws were neither imperial nor metric. The threads were perfect but the hex didn't work metric and was loose imperial . . . go figure!!!I'll put on new pads and update if any issues.Because I ride with my dog, I ride the brakes a lot, mostly the rear, like to keep it below 10 mph so he doesn't overheat. Every ride has at least 1000 feet of elevation gain and lost, some 1800, lot of braking.

I needed to set up 2 new sets of disc wheels which of course are purchased without rotors. Being a total novice at configuring discs, I had no idea what to buy in terms of rotors, especially because most disc rotors are designed and sized with mountain bikes foremost in mind.Various choices of rotors manifested themselves at prices of $40-$50 apiece, perhaps more. These stood out as being very low priced and on paper appearing to be a good match for our road bikes, so I thought that for about $18 a pair, why not give these a try? After trying just one pair, the results were outstanding - they seemed very true and were totally quiet in operation, right from the very first hard stops to bed them in with my pads. So I went ahead and bought another pair for my wife's bike, with the same pleasing result.Time will tell of course after more miles of typical riding, but early results are VERY encouraging!

I purchased a few of these rotors and so far 2 of them have issues. After installing new pads and mounting the rotor I proceeded to bed the brakes. I began to feel the brakes jerking / pulsating when applying the brakes. The other problem is that you will not know there is a problem by visually inspecting them. You need to install and use them to see if there is any issue. This is unacceptable as I also ship out rotors to customers.How can this company ensure the rotors do not have any issues. I hope the seller can reach out to me and provide a solution. I am curious what the tolerances are?
